Paper Title:
Study on the Preparation and Properties of PEG Phase Change Materials Fixed by Semi-IPN
  Abstract

Semi-IPN phase change material (PCM) which is suitable for the temperature adjustment textile field is prepared by solution copolymerization. The structure of framework material is a three-dimensional network prepared by N-hydroxymethyl acrylamide, and the phase change material is prepared by polyethylene glycol with molecular weigh 2000. The orthogonal experimental method is used for determining the optimum formula and investigating the various factors on the phase change material properties. Structure and properties of the composite properties are synthesized by SEM, DSC, TGA. The result shows: the advanced process of making composite phase change material is that PEG owns 70% of the overall mass fractions, initiator owns 2.5% of monomer mass fractions, the molar ratio of cross-linker monomer is 1:8, the reaction time is 3 hours, and mass ratio of monomer to water is 1:6. The prepared composite material is distributed uniformly of framework holes, and it has a well fixed effect to the phase change material, which the phase transition temperature is 32.92 °C, the enthalpy is up to 108.41 J / g. It also has a good thermal stability, and applies to the spinning environment which the temperature is not higher than 300 °C.
