Polymer composites with high thermal conductivity are used in electric devices. The objective of this paper is to study the difference in thermal conductivity of polymer composites measured by steady state method and transient method. Finite element analysis of thermal conductivity measurement of steady state method and transient method was performed using two-layer models. The two-layer model consists of surface layer and thermal conductive layer. The effect of thickness and thermal conductivity of surface layer on the thermal conductivity of the model was discussed. The result showed that thermal conductivity obtained from transient method was higher than that obtained from steady state method. Moreover, decreasing thermal conductivity and increasing thickness of surface layer led to decrease in thermal conductivity of the model.
