Many classic and new models predicting the effective thermal conductivity of polymer matrix compo-site are summarized and their different characteristics are analyzed comprehensively by comparing each other.Mean-while,factors influencing the composite's thermal conductivity are discussed in detail.Then the most frequently used models are recommended with proper application conditions according to the study of composites with carbon nano-tubes and the problem that the generality of those models is not very good is also proposed,At last,it is pointed out that the search direction of thermal conducting polymer matrix composite is as follows.New nanofillers with high ther-mal conductivity should be found and new composite technology should be developed to form effective thermal circuits in the matrix,so that the thermal property of the composite can be improved.
