Shape-stabilized phase change material/nylon composite based on recycled diatomite

Shape-stabilized phase change material/nylon composite based on recycled diatomite

In this study, waste diatomite from the brewing industry was first purified by heat treatment to recover its pore size and surface area. Subsequently, the purified diatomite (PD) was utilized to prepare environmentally friendly polyethylene glycol (PEG)/diatomite shape-stable phase change material (...

Zusammenfassung:In this study, waste diatomite from the brewing industry was first purified by heat treatment to recover its pore size and surface area. Subsequently, the purified diatomite (PD) was utilized to prepare environmentally friendly polyethylene glycol (PEG)/diatomite shape-stable phase change material (SSPCM) by a simple direct impregnation method. PD shows a high surface area of 59.41 m2g-1 and low organic impurities (
