Synthesis and characteristics of hygroscopic phase change material:n Composite microencapsulated phase change material (MPCM) and diatomite

摘要

This paper prepared a new kind of hygroscopic phase change material using MPCM and diatomite. The composite can absorb/release not only thermal heat, but also moisture. The shell material of MPCM was prepared with methyl triethoxysilane (MTES) by sol-gel method, and a kind of alkane mixture was used as the core material. The diatomite was used as hygroscopic material. The morphology of the microcapsules and the diatomite were measured by the scanning electron microscopy (SEM). The thermal proper
