Max Planck Institute for Polymer Research

Whether microchips and sensors in clothing or solar cells on a tent roof – polymer electronics makes such technical applications possible. Scientists at the Max Planck Institute for Polymer Research in Mainz are searching for suitable conducting polymers for these applications. This is, however, not all they do: they investigate polymers in all their different facets – their production, their physical properties and their applications. This is because polymers are becoming increasingly important as materials – not only for flexible, low cost electronics, but also, for example, as minute capsules that can contain drugs that can then be transported specifically to the area affected by the disease. Moreover, the researchers in Mainz are developing new procedures to spectrographically investigate polymers and to simulate their behaviour on the computer. They also work with soft matter, which, like wine gums, combines the properties of solid bodies and liquids.

By means of two examples, graphene nanoribbons and dimensionally stable dendrimers, I describe complex polymer syntheses and their great benefits for electronics on the one hand and gene therapy on the other. The first message I want to convey is that for ambitious goals in materials research, synthesis cannot only be "simple and practical," and the second message is that innovation needs the right people and partners. more

Photocatalytic water splitting

2017 Backus, Ellen
Chemistry Material Sciences Solid State Research

The sun is a well-known source of energy that has been heavily used in recent years. After long-term research and optimization, solar cells which convert solar energy into electrical energy, make it possible for many households and municipalities to use energy in an environmentally friendly manner by installing them on roofs and fields. However, this generation of energy is dependent on weather and daylight. The energy requirement, on the other hand, is usually not proportional to energy production. For this reason, the development of energy storage is becoming a major factor.

The future of polymer electronics

2016 Blom, Paul W.M.
Cell Biology Chemistry Material Sciences Solid State Research Structural Biology

Conjugated polymers can be processed from solution; this attractive feature opens up the realization of roll-to-roll based production processes. Yet commercial success has been hindered. The MPI-P recently demonstrated that the intrinsic properties of conjugated polymers have been masked by defects and therefore have not been fully exploited so far. Our aim is to uncover and characterize these intrinsic properties and improve them further. Using polymer blends, novel properties and nanostructures are realized by controlling the phase separation between various functional polymers.

The economic losses due to corrosion in industrialized countries can represent up to 6% of gross national product. This explains the emphasis placed on the research dealing with corrosion protection. As part of a collaboration with the Max Planck Institute for Iron Research in Düsseldorf, we have produced new coatings for an adequate corrosion protection. We studied corrosion attacks and clarified the fundamental aspects of self-healing and anti-corrosion mechanisms.

MolProComp: molecular process computation

2015 Kremer, Kurt
Chemistry Complex Systems Material Sciences

Macromolecular structures and functionality, ranging from biology to photovoltaics, are the result of non-equilibrium processes. Though crucially important, a basic understanding of the underlying processes on a molecular level is missing. Thanks to recent developments it is now possible to observe such processes over numerous time and length scales. MolProComp takes up these advances and will develop computer simulations methods aiming at the understanding, control and manipulation of such processes.

Superamphiphobic coatings

2015 Vollmer, Doris; Papadopoulos, Periklis; Butt, Hans-Jürgen
Chemistry Complex Systems Material Sciences
Self-cleaning surfaces have existed in nature for a long time. Microstructures on lotus leaves lead to a strong water repellency and ensure that water drops roll off while dragging down dirt with them. This effect is much more difficult to achieve with oily substances. Lately, new surfaces have been developed which not only repel water, but also oil and even human blood. New applications, such as a solvent-free synthesis of polymeric particles or the production of more efficient gas membranes, may become possible. more

Organic electronics has established itself as a new technology for widespread microelectronic applications, e.g. flexible monitors, electronic newspapers, non-contact acquisition of data through transponders and smart labels. Most of these applications require memory functions, preferably the kind that save data when the electricity is switched off and which can furthermore be programmed electronically, deleted and read. more

Glass that cleans itself – superamphiphobic coatings

2013 Vollmer, Doris
Chemistry Material Sciences Solid State Research
Glasses, windscreens and windows have one thing in common: They become dirty. In the field of photovoltaic we are fighting against dirt adhering to solar cells as well. Meanwhile, there are coatings on which water drops hardly adhere. However, this does not apply to organic liquids. Coatings are rather seldom repelling oils, water, soapy and protein solutions at the same time. Not only oils but red wine would roll off these surfaces without leaving stains. An almost fractal structure consisting of silica spheres unveils new opportunities in this area. more

Predictive atomistic simulations unravel the details of heat transport in nanostructures and pave the way to engineer materials at the nanoscale. Here we illustrate applications of atomistic simulation tools to the study of heat transport in silicon-based thermoelectric materials and nano-devices and in carbon nanostructures. more

Several new laser-based vibrational spectroscopic approaches are presented here, aimed towards the realization of this dream, with a specific emphasis of watching molecules at work on surface and interfaces. more

Physics, Chemistry, Biology and Medicine: Spotlight on the spin

2011 Münnemann, Kerstin; Hinderberger, Dariush
Material Sciences
Measurement methods which are based on magnetic resonance have become very important in the fields of modern research and medical diagnostics these days. Magnetic resonance spectroscopy and magnetic resonance tomography (MRT) use the quantum mechanical properties of the spin as a spy to gain a very detailed insight into the morphology of materials and tissues. Thus, new hyperpolarized contrast agents used in MRT now make it possible to visualize processes in the human body and provide a whole new range of possible applications in the medical diagnostics of tomorrow. more

Organic electronics: environmental better, more economic and soon more efficient too

2011 Baumeier, Bjoern; Andrienko, Denis
Material Sciences
Electronic devices made of organic materials have certain advantages that other, inorganic devices miss. The materials that have been developed so far are however not efficient enough and are thus unfit for an area-wide application. This is due to fundamental processes on the molecular and nuclear scale which determine the storage and transportation of the charge. These processes are determined by a complex interplay of material compositions and their interactions. The Max Planck Institute for Polymer Research uses numeric simulations in order to examine and understand these processes. more

Dynamic Surfaces with Triggerable Functional Levels

Strategies to control phenomena at the interface between artificial materials and biological systems are relevant for many fields ranging from biosensing to tissue engineering. The inertness and static character of artificial surfaces contrasts with the dynamic, reversible and evolutionary character of biological processes. This gap can be filled with novel strategies that allow precise and active change of the surface properties by application of ready-available and biological friendly external fields. more

Drops like it soft – Condensation on soft surfaces

Chemistry Material Sciences
The formation of dew, i.e., condensation of water on cold substrates involves the formation of complex patterns, breath figures. Growth and merging of droplets and the overall volume of condensed liquid depend sensitively on the local environment of the droplets and the mechanical properties of the substrate. The softer the substrate, the more drops condense onto it, and the more strongly the drops interact with the substrate. more

Organic Semiconductors for Electronic Devices

2009 Baumgarten, Martin; Li, Chen; Feng, Xinliang; Müllen, Klaus
Chemistry Material Sciences
Organic semiconductors allow the preparation of low-cost, flexible and large-area processable devices such as light-emitting diodes (LEDs), field-effect transistors (FETs), photovoltaic cells (PVs), and sensor materials. Thereby a lot of basic science is involved, since besides of technical optimizations there is also a strong need for new synthetic building blocks. Thus actual research focuses on the development of tailored functional organic materials and their processing as films of suitable morphology for the individual applications. more

Chemistry Material Sciences Solid State Research
Three novel techniques for micro- and nanostructuring soft and delicate materials, such as polymers are presented. Compared with conventional processes they have the advantage of being low-cost, fast, and straightforward. They are based on simple physical and chemical effects: polymers can be crosslinked with plasma or UV-irradiation, and they can be locally solved or swollen with solvents. more

The Molecular Nose

2007 Sinner, Eva-Kathrin
At the MPI for Polymer Research, the combination of chemistry and biology resulted in the development of novel experimental strategies for investigation of membrane proteins. Employing the well-known strategy of in-vitro transcription and translation, proteins with subtle sensing capabilities, such as olfactory receptors, are generated and characterized. To obtain such proteins, an artificial membrane system is generated and a cell extract containing the genetic information of the receptor species of interest is added on the membrane surface. The protein synthesis machinery in the cell extract is still functional and inserts the olfactory receptor molecules into the lipid membrane. Finally, we can investigate the resulting proteins by optical and biochemical methods. more

Soft Matter Dynamics

2005 Fytas, George
Our images of organized soft matter, e.g. polymers, colloids, are dominated by static structures that provide only snapshots of the possible conformations. Since the typical energies are of the order of the thermal energy, soft matter is amenable to large fluctuations. Structural dynamics are essential for material function. The study of molecular motions over broad time and spatial ranges challenges both experimentalists and theoreticians. Three selected topics from ongoing projects should exemplify such challenges. more

For the first time images of gases can be acquired my magnetic resonance techniques due to recent developments in optical polarization methods. This can be used to investigate the lung with unrivalled spatial resolution. The morphology and function of the lung down to microscopic levels can be characterized by the combination of these methods with further physical information. more
We present three different fields of research in which analytic theory and computer simulation of polymers play an important role. First the relationship between the specific adsorption of single chemical groups in a polymer onto a metal surface as well as the influence on the global chain conformations are studied. The second example establishes a relation between the chain conformations and the so-called entanglement length that determines the rheology of melts respectively the module of elastomers. The third example shows that based on a relatively simple DNA model ("semi flexible worm-like chain") basic phenomena of the DNA repositioning alongside the chromatin can be understood. more
