Abstract

Microcapsules with a silicone liquid core surrounded by a polymeric shell were synthesisedthrough the controlled phase separation. The dispersed silicone phase consisted of the shellpolymer PMMA, a good solvent for the PMMA (dichloromethane, DCM) and a poor solvent(methylhydrosiloxane dimethylsiloxane) for thePMMA. The morphology of the PMMA micro-capsules was investigated by ATR-FTIR and byoptical microscopy. Microcapsules were preparedwith different emulsifiers and different concen-trations of acetone and PMMA in the oil phase.The thermal stability of the PMMA microcapsuleand the content of the silicone oil core wereassessed by TGA.1H-NMR spectroscopy and anextraction method were also used to determine the content of the silicone liquid core in the microcapsules.
