Preparation and Characterization of Heat-Storage and Thermo Regulated Composite Material by Reaction Extrusion

Abstract:

Phase change materials exhibiting excellent heat storage property can be used for energy saving applications. The textile made by fiber with PCMs can provide human body a comfortable microenvironment. The heat-storage and thermo-regulated fiber with active poly (ethylene glycol) acrylate (PEGA) as phase change materials was prepared by reaction extrusion. Poly (ethylene glycol) acrylate was grafted to polypropylene (PP) during the extrusion process. Combining preparation with functionalization, this easy method makes the entire producing process more efficient and simple. We used nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FT-IR) to characterize the structure of PEGA and PP-g-PEGA, and the results proved the synthesis of graft copolymer. Differential scanning calorimeter (DSC) was used for characterizing functional fibers thermal property. The fiber with fixed enthalpy provided heat storage and themo-regulated property. The melting and crystalline latent heat of best sample is 6.83J/g and 1.32J/g, respectively. The crystalline temperature region is from 41.67°C to 34.23°C, which is close to mean body temperature and it shows great potential in functional textile.
