Studies on Preparation and Properties of PEG/MMT Solid-Solid Phase Change Material

Abstract:

This paper details the preparation of one kind of PEG/MMT solid-solid phase change materials. With polyethylene glycol (PEG) as the phase change materials, montmorillonite (MMT) as skeletons, through the graft copolymerization method, prepare PEG/MMT solid-solid phase change energy storage materials. The structure, the phase transition behavior and thermal stability of PEG/MMT phase change materials were analyzed and studied by infrared spectroscopy (FTIR), thermogravimetry (TG) and differential scanning calorimetry (DSC), and studied the influence of different molecular weight PEG on the capability and structure of the material, polymer phase change energy storage behavior and crystallization behavior. Finally, The PEG/MMT solid-solid phase change material could improve enthalpy value and thermal stability.
