Study on the behavior of phase change and crystallization of MGPM/opal composite materials
In this paper, a novel solid-solid phase change heat storage composite material of MGPM/opal with MPEG chain structure was synthesized by the way of polycondensation. Wide-angle X-ray diffraction (WAXD), differential scanning calorimetry (DSC) and hot stage polarizing microscopy (POM) were performed to investigate the crystalline structure, crystalline behaviors, crystalline morphology and thermal stability of the composite materials. The results indicated that the addition of natural nano-material of opal promoted the crystallization and increased the crystallization speed of MPEG. When the mass fraction of opal was 0.7%, the crystallinity of the copolymer was the highest. Compared to the pure MPEG, the melting enthalpy and the crystallization enthalpy of the copolymer were increased by 10.578J/g and 8J/g, respectively. The thermal stability of the copolymer was good, and it increased with the increase of opal.
