Abstract:Thermal conductive polymeric materials are superior to metals in electronic engineering, cooling systems and heat transfers. Approaches to improve the thermal conductive properties of polymer are to synthesizer high heat conductive polymers and composite polymer with high thermal conductive filler. The results of study on thermal conductive properties of polymer and their composites were reviewed with 39 references, including the concepts of heat conducting, the effecting factors of thermal conductivity of polymer materials, etc. The resent advances in heat conductive polymeric composites and the high conducting fillers were described. The researching directions of thermal conductive polymeric materials are studies and developments of nanometer fillers with high heat conductivity, modifying polymer resin by physical chemistry methods, the technologies of compounding polymer with high conductive fillers, the researches of heat conductive mechanism and model and searching the methods and processing of high heat conductive polymer structured materials. These have important significances to develop thermal conductive polymeric materials.
Keywords:thermal conductive polymeric material  heat conducting fillers  nanocomposites  thermal conductivity
