The use of nanoparticles in hybrid and polymeric matrices has been investigated. Different types of nanocomposites have been prepared. The ormosil type based on organoalkoxy silanes shows surprising properties with respect to solid content and relaxation. Thick films for coatings, embossed films for diffractive purposes, high temperature stable binders for glass fiber insulation materials and printing pastes have been prepared. The nanomer type with nanoparticles homogeneously dispersed in polymer matrices led to optical adhesives with improved properties with respect to T g and thermal coefficient of expansion. The inverse nanomer type with the nanoparticles forming a percolating network was developed for photo curable optical interference layers on plastic, for example to AR coating by using simple wet chemical coating techniques.
