| Abstract: | Microcapsules for self-healing material were synthesized by in-situ polymerization with urea-formaldehyde resin as the shell material and dicyclopentadiene as the core material.The formation process of microcapsules was observed by using optical microscopy(OM).The chemical structure was characterized by fourier transform infrared(FTIR).The thermal stability and particle size distribution of microcapsules were analyzed by thermogravimetric analysis(TGA) and laser particle size analyzer.The results indicate that dicyclopentadiene is well encapsulated by urea-formaldehyde resin.The microcapsules with smooth surface and good dispersibility are prepared.The microcapsules are obtained with good chemical stability and narrow particle size distribution,and the average particle size is 10.394μm. |
