AB - The results of the study of the applicability of various methods for calculating the values of the “generalized conductivity” of heterogeneous systems for predicting the dielectric constant of composite materials based on a polymer matrix and a filler are presented. To predict the dielectric constant of a material with a disordered filler arrangement, it is recommended to use the formula logε = \documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$$\sum\nolimits_{i = 1}^n {{{\Theta }_{i}}{\kern 1pt} \log {\kern 1pt} {{\varepsilon }_{i}}} $$\end{document}, where n is the number of components, εi is the dielectric constant of the ith component, and Θi is the relative volume concentration of inclusions in the mixture. Consideration of the calculation results showed that, for composites with titanium dioxide as a filler, the calculated value of ε closest to the observed one is obtained when using the dielectric constant of titanium dioxide perpendicular to the optical axis (with the layers oriented perpendicular to the electric-field lines) (ε = 89). For composites with fibrous fillers, the calculated results can be interpreted as evidence that fibrous fillers in the composite are located mainly perpendicular to the direction of the applied electric field during the measurement.
