Material Properties of Polymer Nanoparticle Composites for Micro Optical Applications

摘要

Nanosized ceramics, highly dispersed into polymer matrix materials, are widely being discussed for the modification of polymer properties. The addition of ceramics with primary particle sizes of several nanometres allows specific tailoring of relevant optical properties, e. g. refractive index and optical damping. Also the influence of ceramic nanoparticles on the mechanical properties e. g. tensile strength, of the polymers, was analysed. A process chain for polymer nanoparticle composite formation using improved dispersing methods to destroy ceramic agglomerates was developed to obtain polymer nanoparticle composites. In microsystem technologies the durability of a polymer device is of great importance. Therefore, the influence of elevated temperatures on material properties like refractive index, optical damping and tensile strength was investigated.
