| Abstract: | A solid-solid phase change energy storage composite material with polyethylene glycol single methyl ether(MPEG) chain structure,which chould be abbreviated as MGPM/opal,was synthesized by the way of monomer polycondensation with phase change.Wide-angle X-ray diffraction(WAXD),differential thermal scanning calorimeter(DSC) and hot stage polarizing microscope(POM),thermogravimetry(TG) and other testing methods were performed to investigate the crystal structure,crystallization behaviors,crystalline morphology and thermal stability of the composite materials.The results indicate that the addition of natural nano-phase materials opal improves the crystallization behavior and increases the crystallization speed of MPEG.When the mass fraction of opal is 0.7%,the crystallinity of the copolymer is the highest,when the phase change enthalpy comes to 109.07 kJ/g.Compared to the pure MPEG,the melting enthalpy and the crystallization enthalpy of the copolymer increase by 10.578 J/g and 8 J/g,respectively.The thermal stability of the copolymer is good,and it increases with the increase of opal. |
