Abstract:

Monodispersive poly(glycidyl methacrylate)(PGMA) microspheres were prepared by dispersive polymerization and then were hydrolyzed to obtain oil-in-water Pickering stablizer. Based on phase separation mechanism, microcapsulated phase change material(MePCM) with PSt and PGMA composite shell were prepared by Pickering emulsion polymerization. The MePCM was characterized by large diameter(76 μm averagely), high core content[w(dodecanol)=83%] and excellent energy storage capability(phase change enthalpy of 174 J/g).

Key words: Microencapsulated phase change material, Pickering emulsion, Polymer microsphere, Dispersion polymerization
