The article presents the results of studies of the structure and properties of nanodispersed silicon carbide particles using the method of infrared spectroscopy of disturbed total internal reflection, as well as electret thermal analysis. Temperature ranges of the occurrence of TST in the polymer matrix have been established, which may be due to the processes of melting and oxidation of the polymer matrix, accompanied by the release of charge carriers. The activity of silicate-containing particles used to modify polymer matrices has been analyzed. It has been shown that the introduction of SiC particles into the polymer increases the intensity of TST peaks. The prospects of using ultrafine SiC particles obtained from natural raw materials for the modification of polymer materials are considered.

The article considers the influence of various technological methods for obtaining nanosized silicate-containing particles. Each of the methods has its advantages and disadvantages, none of them is universal. It is shown that, depending on the methods of formation of particles, their activity changes. Silicon carbide particles obtained as a result of the thermolysis process with preliminary chemical treatment from natural raw materials of organic origin are of interest for further research. These particles have an increased charge activity in relation to other studied classes of charged particles.
