This review is intended to analysis of works in field of creating electrically insulating heat-conductive polyimide composite films based on powders of micro- and nanoparticles with high dielectric and heat-conductive properties for use as effective thermal interface materials in various electronic devices in instrument engineering. Particular attention is paid to studies on the effect of size of nano- and microparticles of inorganic fillers on heat-conducting, dielectric, and physic-mechanical properties of nanocomposite polyimide materials. Carried-out analysis of results of works on studying dependence of thermal conductivity on ratio of micro- and nano-sized particles in mixtures and their amount in polyimides and on conditions of their polymerization for confirming possibility to increase values of thermal conductivity of promising polyimide materials from 0.12 W/m·K up to 5-10 W/m·K.
