Abstract
In this study, phase change microcapsules were prepared by in situ polymerization using paraffin as core material, poly(MMA -co- MAA) as shell material, Tween60/span60 as emulsifier. The surface morphology, thermal properties and particle size distribution of the prepared microcapsules were investigated by using SEM, TGA, DSC and ELS. The effects of paraffin core content and amount of emulsifier on the properties of microcapsules were studied.
