Abstract
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.
