| Abstract: | Thermal conductive polymer-based composites made by blending polymer with high thermal conductivity filler were applied in heat exchange occasion possessing high requirements for corrosion stability and saving energy, and accorded with the requirement of the heat exchange equipment as new materials. The prediction of effective thermal conductivity of polymer-based composites is complex. Many prediction methods of effective thermal conductivity of polymer-based composites are summarized, including minimum heat resistance, heat resistance network, Fourier law, asymptotic homogenization and percolation theory. Their features are given. Suggestions for their applications are put forward. |
