Fraunhofer IKTS develops inorganic-organic nanocomposite materials that combine metal oxides (SiO2, TiO2, ZrO2, Al2O3) with silicones, siloxanes, (meth)acrylates, epoxides and other organic polymers on the nanometer scale, so that tailor-made structures can be established.

Further interesting combinations of physical and chemical properties are achieved by combining plasma spray coatings (ceramics, metals, carbides, cermets) with such nano-composites (PLASMAGEL), e. g. non-stick effect, electrical insulation, wear resistance.
