A significantly reduced gas permeation in polymer composite films filled with clay indicate the crucial role of microstructural properties for the functional performance of organic polymer films.Easy-to-functionalize surfaces based on polymer coatings with tunable surface chemistries permit today the implementation of desired biological reactions like the resistance to protein adsorption or bacterial adherence and support the healing process after the insertion of a medical implant.A nanometre scale surface topography can significantly influence the protein adsorption and, as such, the interactions of cells and bacteria. Moreover, the surface morphology of a textured, nanostructured polymer surface can itself induce a lateral orientation of an adsorbed polypeptide like poly-(l-lysine) (PLL). The surface nanostructure can also affect the assembly of proteins like the amphiphilic, anisotropic fibrinogen, which plays a key role in the implant surface induced blood coagulation cascade: On nanostructured ultra-high molecular weight polyethylene (UHMWPE) films fibrinogen adsorbs in a compact adsorbate. The latter impedes the formation of ring networks, which are typical on flat, structurelesssurfaces indicating that protein–protein interactions are active. While partially keeping their native trinodular folding conformation, the fibrinogen molecules in these compact adsorbate protein films change their dynamical and functional properties and acquire a significantly increased residence time, as could be observed in a single molecule tracking experiment.Future key applications will comprise the next-generation lithography in the semiconductor industry that could rely on the bottom-up directed self-assembly (DSA) of block copolymers to create sub-10 nm nanostructures. Furthermore, advanced polymer-based templates will serve as compatibilizers and to induce a selective or spatially localized attachment of micro and nano-objects, as, e.g., metallic nanoclusters.
