The results of experimental and theoretical studies of the crystallization regularities of polymer micro- and nanocomposite materials based on polyethylene, polypropylene and polycarbonate filled with high-heat-conducting fillers – carbon nanotubes, microparticles of aluminum or copper are presented. The mechanisms of structure formation at the stage of the formation of individual ordered structures in the material and the formation of such subregions in the entire volume of the polymer composite were established based on the analysis of the crystallization exotherms obtained within the scope of the nucleation equation and Kolmogorov-Avrami.

The results of experimental studies of the thermophysical properties of high-heat-conducting polymer micro- and nanocomposite materials based on various polymer matrices (polyethylene, polypropylene, polycarbonate and polymethylmethacrylate) and fillers (carbon nanotubes, aluminum and copper microparticles) are presented. The data on study of the heat conductivity coefficient, specific heat, and heat of crystallization of the composites in question are analyzed in a wide range of changes in the mass fraction of fillers from 0.2 to 10%.
