Research Area I: Polymer Synthesis / Catalysis

Polymer technology still is dominated by functional polymers, in turn enabling to control their threedimensional ordering and organization. Key-point in this endeavor is the synthetic control over architectural design, achieving synthetic and dimensional flexibility of macromolecules as well as a profound structural analysis. We do address these issues by methodological development of synthetic methods based on combinations of living polymerization techniques with reliable functionalization strategies known from synthetic organic chemistry, including "click"-based methods. Besides living radical polymerization techniques (ATPR, RAFT, NMP) a focus is placed on ROMP, GRIM and living cationic polymerization techniques (LCCP). Based on such approaches, polymer architectures (eg.: synthesis of functional graft-, cyclic-, star-polymers) as well as issues of site-specific integration of interactions (such as hydrogen bonds, ionomers, blockcopolymers) into tailored macromolecules can be enabled. Altogether this allows developments of a platform for the design of functional polymers, planning and directing various self-assembly processes.


Figures Synthesis and analytical separation of multifunctional polymers.

Another important aspect concerns a true and reliable characterization of functionalized macromolecules in the sense of organic molecules, based on chromatographic techniques coupled to high resolution mass spectrometry. Besides the development of LC/ESI-MS and GPC/LC-MALDI-methods our main developments in this area are coupling interfaces to either ESI-TOF or MALDI-TOF-MS for the analysis of macromolecules or crossover-reactions. Thus a special feature concerns separation techniques of two-dimensional chromatography (2D-LC/GPC), which enables endgroup/block-specific separation and size-dependent identification of macromolecules using hyphenated direct MS-specific detection. This in turn enables to address the synthetic preparation of more complex polymeric architectures, in particular sequence-specific polymers and cyclic polymers in higher structural precision.

Research Area II: Self healing polymers / Nanocomposites

Polymeric materials need new concepts to address new value-added markets. As often polymerization technology reaches constraints of improvement, new research areas can push the limit of exploitation into new markets. We do address new and emerging areas of polymer science, such as self-healing materials, fuel-cell membranes or issues of friction or wear, where control of the intrinsic threedimensional structure of polymers is important for their improved function.  Thus one current activity is dedicated to self healing polymers - an immanent challenge in macromolecular chemistry, where a basic understanding of chemical and physical processes in polymers forms the basis for the design of new polymers with self-healing properties. Another field of research is dedicated to the molecular design of electrolyte membranes to enable improved design - a still challenging area in membrane-technology.  Furthermore, ionic and polymeric ionic liquids are enormously important components in membrane technology, sustainable chemistry as well as in the field of tribology. A development of these areas into the design of new electrolyte membranes, into the field of tribology and self-healing materials is envisioned.






















Figures Self-healing polymers via (right) capsule-based crosslinking reactions and (left) via supramolecular assembly or disassembly.    

Classical nanocomposite-materials based on silica and graphite can now be significantly improved by the use of carbon nanotubes or graphene, often hampered by their low dispersibility in polymeric matrices. Control of interfacial interaction between inorganic/organic nanocomposites has been addressed vastly in our group by using grafting-from technology and click-based surface modification of a large number of inorganic (nano/micro)-particles, thus effecting selective nanoparticle attachment or dispersion in poly(olefinic) matrices

Research Area III: Biomimetic polymers

PApplication of polymers within living organisms requires concepts to implement biocompatibility and bioavailability, additionally introducing biomimicry via molecular design. We thus are expanding the interplay between polydisperse macromolecules and biological molecules by hybrid-materials displaying properties useful for living organisms. Polymers and lipid molecules meet in their dynamic and amphiphilic character when present at interfaces, specifically within artificial bilayer-membranes. Current activities aim at the engineering of monolayers and closed-bilayer capsules, generated from either lipid vesicles and/or polymersomes, addressing enhanced mechanical stability as well as controlled porosity of the final capsules useful for drug delivery and artificial folding.


Figure  (1) Interaction of amphiphilic block copolymers and surface modified nanoparticles with lipid membranes. (2) Protein interaction (cholera toxin B) with ganglioside GM1 funtionalized hybrid lipid polymer membranes (A homogeneous mixed and B phase separated hybrid membrane).

A particular emphasis is directed towards the understanding of lipid/polymer interaction in ordered assemblies at the bilayer-interface, allowing to assemble nanosized objects (nanoparticles, large (amphiphilic) biomolecules or biochemical receptors) at specific locations of an interface, either on a polymer/lipid (membrane)-interface, or at liquid/liquid interfaces. Main aims here concern the use of amphiphilic, biocompatible polymers for use in medicine and drug delivery, generating membranes with unusual properties based on the microphase separation of blockcopolymers. Together with introduced STEALTH-properties (via eg. PEG- or poly(oxazoline)s) these membranes are highly variable in their properties with respect to their selective permeability towards nanoparticles and small molecular aggregates, enabling issues of receptor clustering and triggering.

Research Area IV: Nanoscopic ordering of nanoparticles onto functional macromolecules

Spatially separated domains in blockcopolymers can be used as scaffolds for assembly processes, in particular for the attachment of nanoparticles and nanosized objects. One main focus of activities is directed to the synthesis and use of designed polymeric surfaces and interfaces enabling the stable binding of nanoparticles onto derivatized (microphase-separated) surfaces for further use in solar-cell-technology, energy storage and catalysis. Self-assembly-processes of nanosized objects (i.e.: Au-NP’s, CdSeNP’s, CdSe-nanorods) on specific locations of the surface are studied, extending this concept to the assembly of BCP’s within nanotubes (50 - 400 nm, Al2O3) by melt- or solution infiltration of block-copolymers (BCPs), generating tubular structures with multi-walled architectures.

Figure  Synthesis of block-copolymers and their melt-infiltration into nanopores, generating high-surface nanotubes for subsequent nanoparticle assembly.


TEM-measurements of the generated BCP’s reveal complex tube-wall morphologies consisting of concentric lamellae parallel to the tube axis, thus enabling control over the chemical functionalities. The crystallization of polymer segments within the polymer chain can serve as additional structuring force for the self assembly into 2D- and 3D-array structures and is investigated as an additional driving force for patterning and structure formation. Photoactive materials for solar cell technology or catalysis by selectively embedded nanoparticles are two possible applications of these research investigations.
