Photoinduced Microencapsulation of Microcapsules Containing n-Octadecane with P(APUA) and P(AMA) Shell

Abstract:

An advanced microencapsulation for n-octadecane has been successfully developed via UV photoinduced polymerization in this study, which was characterized by some superior qualities (e.g. rapid microencapsulation, energy-saving and environment-friendly) compared to conventional microencapsulation process. The morphology, microstructure and properties of the microencapsulated n-octadecane with poly (aliphatic polyurethane acrylate) and poly (allyl methacrylate) as shell were respectively investigated by FE-SEM, TEM and DSC. The effects of UV irradiation time, shell material types and feed ration of shell-forming monomer to n-octadecane on the morphology and structure were investigated in detail. Furthermore, the photoinduced microencapsulation mechanism was interpreted clearly as well. Besides, the phase change properties were studied as well.
