▎ 摘　　要

An analytical model for the effective thermal conductivity in graphene nanoplates (GNPs) based composites is presented. The theoretical formula gives good agreements with the existing experimental data available in the literature. In particular, the present model well shows the nonlinear dependence of effective thermal conductivity enhancement ((K-e - K-m)/K-m) on the GNP volume fraction (f), and it yields a power law (K-e - K-m)/K-m similar to f(alpha) (1/2 < alpha < 2) (1/2 < alpha < 2). Some interesting findings in thermal conductivity behavior of GNP composites based on the present model are also discussed. (C) 2012 American Institute of Physics.
