Abstract
In this study, microcapsules containing n-Octadecane (melting point 28 oC) using methyl methacrylate (MMA)- methacrylic acid (MAA)-Ethylene glycol dimethylacrylate (EGDMA) co-polymer shells were synthesized by suspension-like polymerization. After introducing 3-Methacryloxypropyltrimethoxysilane-modified AL2O3 into the oil phase, , microcapsules with P(MMA-MAA-AL2O3) crosslinking shell was prepared. The surface morphology, diameters, phase change properties and thermal decomposition temperature of microcapsules were investigated by using Scanning Electronic Microscope (SEM), Differential Scanning Calorimeter (DSC), and Thermogravimetric Analysis (TGA). The effect of microcapsules on temperature regulation has been observed.
