Summary

There were studied optical properties of polymeric films of poly(N-vinylcarbazole) (PVK), polycarbonate (PC), polystyrene (PS) and films of these polymers modified with SiC nanoparticles of size between 20 and 30nm. Thin polymeric films were deposited on glass plates with spin coating method, using polymer solution in tetrahydrofuran (THF). In order to determine optical parameters of these new materials, the reflection spectrum was examined in the range between 350 and 860nm, using a reflection probe and an integrating sphere. In order to determine the thickness of examined films, ellipsometric measurements were performed. The examination demonstrated that a small content of SiC nanoparticles in polymers changes the refractive index of the sample without causing its optical heterogeneity. But an increasing content of nanoparticles causes their aggregation, which strengthens light diffusion.


Key words: thin polymeric films, SiC nanoparticles, nanoparticle-modified polymers, optical properties
