Preparation and characterization of a novel polymeric based solid–solid phase change heat storage material

Here we reported a two-step procedure for preparing a novel polymeric based solid–solid phase change heat storage material. Firstly, a copolymer monomer containing a polyethylene glycol monomethyl ether (MPEG) phase change unit and a vinyl unit was synthesized via the modification of hydrogen group of MPEG. Secondly, by copolymerization of the copolymer monomer and phenyl ethylene, a novel polymeric based solid–solid phase change heat storage material was prepared. The composition, structure and properties of the novel polymeric based solid–solid phase change material were characterized by IR, 1H NMR, DSC, WAXD, and POM, respectively. The results show that the novel polymeric based solid–solid phase change material possesses of excellent crystal properties and high phase change enthalpy.
