The electroconductive and thermal conductive properties of polymer composites are investigated. Studied composites are based on epoxy resin (ER) with dispersed copper (Cu) and nickel (Ni). The electrical conductivity of composites obeys the percolation theory with the percolation threshold equal to 9.9% vol. and 4.0% vol. for the ER–Cu and ER–Ni composites, respectively. Several theoretical models are used to describe the thermal conductivity of the metal-filled composites. Using the Lichtenecker model, the value of the thermal conductivity of the composites’ dispersed phase is found to be 35 W/(m$\cdot$K) for Cu and 13 W/(m$\cdot$K) for Ni, that is much less than the thermal conductivity of solid metals. As shown, the filler affects the molecular mobility of polymer matrix that leads to the increase of the glass-transition temperature of the ER–Cu and ER–Ni composites.
Key words: metal–polymer composites, electrical conduction, thermal conduction, glass-transition temperature.
