Abstract

An O/W emulsion of paraffinic phase change material (PCM) was prepared through a sonochemical process for microencapsulation using melamine-formaldehyde resin as the wall material. It was found that the octadecane micelles selected as PCM were successfully formed in water with a diameter of 1-3 ㎛ through ultrasonication for 5 min. Anionic surfactants were found to be more effective than non-ionic surfactants in the formation of emulsions consisting of PCM micelles through a sonochemical process. Spherical PCM microcapsules were obtained from the PCM emulsion and melamine-formaldehyde prepolymer, which was used as the wall material. The diameter of the PCM microcapsules increased with increasing microencapsulation time and the prepolymer to PCM weight ratio.
