제목 | Suspension polymerization based on via Pickering emulsion droplets for thermally expandable microspheres with Core-Shell structure using the SPG emulsification technique |
초록 | To prepare thermally expandable core-shell microspheres, using SPG membrane emulsification and suspension polymerization. The copolymer shells consist of acrylonitrile(AN) and methyl methacrylare(MMA). With aiming to prepare microcapsules having a particle size of 30-50 µm, colloidal silica and poly(vinylpyrrolidone)(PVP) were used as the inorganic Pickering emulsifier and the organic stabilizer, respectively. Suspension polymerization after emulsification of the SPG membrane was carried out to produce uniform particles as compared with the suspension polymerization. In this study, thermally expandable microspheres using the SPG membrane are synthesized with colloidal silica and iso-octane as blowing agents. And the uniformity of the particles according to the size of the SPG membrane was measured. |
