In this paper, polyethylene glycol/boron nitride (PEG/BN) phase change composite was prepared by molten blending method and the influence of the flake size of BN on the thermal conductivity and crystallization behavior of phase change composites was studied. The microstructure, thermal conductivity and phase transition performance of the prepared composites were investigated by scanning electron microscope (SEM), thermal constant analyzer, infrared thermal imaging analyzer and differential scanning calorimeter (DSC). The DSC results of were analyzed by Mo Zhishen method. Results show that larger diameter (50 μm) BN can improve the thermal conductivity of PEG more effectively. When the weight fraction of BN filler content is 40%, the thermal conductivity of phase change composite can reach 5.04 W/(m·K). Under conditions of rapid cooling, BN filler with a diameter of 50 μm can shorten the semi crystallization time and increase the crystallization rate of PEG, and make the phase change composites have a large phase change enthalpy.
