The authors examine the melting and crystallization behavior of a polyethylene/boron nitride composite to understand an unexpected exothermic peak when the BN content was greater than 10 wt. %. Based on these observations, an optimal annealing temperature of the composite was investigated to enhance its thermal conductivity. The appearance of the peak was determined to depend on the different nucleated capability of the different BN aggregates in local area. An annealing ...
