Organic phase change materials like paraffin as phase change material, modified opal as carrier, composite phase change material with proper phase change temperature and larger phase change enthalpy is prepared by hot melt complex mixed. The structure and performance of composite phase material are characterized using SEM, infrared spectroscopy and synthesized thermal analyzer DSC. The results show that the phase change temperature of composite phase change materials is 24.91 ℃, and phase change enthalpy is 64.31 J/g. With every part preserved, phase change particles are distributed in the opal/melted paraffin matrix evenly. Stable composite phase change materials are prepared with opal as carrier and paraffin as PCMs, which are bonded with Vander Waals forces in the form of physical adsorption.
