摘要：

The effect of a high electrically and thermally conductive filler on the crystallization kinetics of low-density polyethylene (LDPE) crystallites has been quantified. An increase in crystal growth rate was found which was consistent with the increase in composite thermal conductivity. However, an anomalous jump, not present in the bulk thermal conductivity, coincided with the end of the critical region in electrical conductivity. The cause of this jump is not absolutely clear; however, we believe the shift is due to the formation of a continuous network of particles causing an increase in local heat dissipation.
