Features of nanocomposites of organic copolymers doped with superfine metal particles under ultrasonic treatment

In this work, we represent the study of 4-aminostyrene copolymers with butyl methacrylate and N-carbazolylethyl methacrylate copolymers with octyl methacrylate doped with superfine nano- and micro dimensional metal particles. In order to improve the degree of dispersion, polymer solutions containing metal particles were exposed to ultrasonic (US) sonication for 0.5 to 10 min. It was shown that the presence of 10-15% of metal particles and US sonication lead to an increase in the microhardness of polymer materials by 3-4 times. Using optical and atomic force microscopes, the structure of thin films was analyzed. The increase in metal particle concentration in the polymer leads to an increase in the dimensions of metal inclusions due to the coagulation of nano- and microparticles into conglomerates. (authors)
