Microcapsules are fine particles whose size ranges from 50nm to 2,000㎛, composed of an excipient polymeric shell and incipient active core component. Microencapsulation of phase-change materials(PCM) has been studied for application to thermal insulation materials, thermal adaptable fibers, etc. In this work, melamine-formaldehyde was used for encapsulation of PCM. The functions and characteristics of microcapsule depend not only on the properties of both core material and polymer shell, but also on various manufacturing parameters such as the solvent, additives and temperature. The various microcapsules were prepared using nonionic surfactants such as NP-9, Tween-20, Tween-80, Span-80, and Brij-98. The pH of the reaction medium was varied from 4~7. The encapsulation efficiency was measured by DSC. The shape and size of the microcapsules were confirmed by optical microscopy, and particle size analysis.
