| Abstract: | The thermal conductivity and its change laws of filled polymer composites materials were discussed in this paper. Model treatments and predicted equations of the heat conductivity of heterogeneous polymer materials were reviewed by investigating and comparing with each other, including heat conductive mechanism of solid materials, predicted models of polymer composites such as Maxwell Eucken, Bruggeman, Cheng Vochen, Nielsen,Y.Agari, D.M. Bigg etc equations, and step by step averaging approach of V. P. Privalko and V.V. Novikov. The equation of Y.Agari has advantage in practicality, and step by step averaging model has higher scientific significance .The effecting factors on thermal conductivity of the composites were analyzed, including compositions, microstructure of polymer composites, dispersion of conductive component in matrix, and conducting macroscopical conditions. |
