| Abstract: | A kind of phase change material microcapsules(Micro-PCMs) with compound wall was prepared. The wall material was made from melamine resin and modified melamine resin with PEG200. Tetradecane was used as core material. IR, XPS, SEM, TG and XRD were used to characterize the wall structure, thermal physic property and morphological property. The relationship between wall structure, mechanical strength and sealability of micro-PCMs was studied. |
