Studies on the Thermal Conductivity of HDPE/C Composites

Abstract

Abstract: Thermal conductivity of HDPE/C composites and its mechanism were studied through SEM and thermal conductivity measurement.The results show that after being treated with coupling agent through pan-milling, the graphite particles will uniformly disperse in HDPE matrix, the interface interaction between graphite and HDPE enhances quite a lot.The temperature detected on the sample surface vs.time shows an excellent agreement with third-polynomial regression: T= A₀+ A₁t + A₂t²+ A₃t³.The thermal conductivity of HDPE/C is much higher than that of HDPE, the temperature-increasing rate of HDPE/C(65/35) composite reaches 1.75 times of that of HDPE.
