Microcapsules are fine particles whose size ranges from 50nm to 2,000㎛, composed of an excipient polymeric shell and incipient active core component. The functions and characteristics of microcapsules largely depend on the properties of the shell. In this work, Melamine-formaldehyde microcapsules containing phase change material (PCM) were synthesized by in situ polymerization and they were treated with various diisocyanates in order to improve the thermal stability of melamine-formaldehyde microcapsule shell. Thermal stability of the prepared microcapsule was measured by TGA and the encapsulation efficiency was measured by DSC. The shape and size synthesized of the microcapsules were confirmed by optical microscopy, SEM, and particle size analysis. |
