Abstract

In this work the investigations of 4-aminostyrene copolymers with butyl methacrylate and N-carbazolylethyl methacrylate copolymers with octyl methacrylate doped with the superfi ne nano- and micro-dimensional metal particles are presented. In order to improve metal particles dispersion degree, polymer solutions containing metal particles were exposed to ultrasonic (US) sonication from 0.5 to 10 minutes. It was shown that the presence of 10-15% of metal particles and US sonication lead to an increase of polymeric material’s microhardness by 3-4 times. With the help of optical and atomic force microscopies the structure of thin fi lms was analyzed. The increase of metal particles concentration in polymer leads to an increase of the dimensions of metal insertions due to the coagulation of nano- and microparticles into conglomerates.
