Study on poly (urea-formaldehyde) microcapsules embedded self-healing composite

摘要

The aim of this study was to develop a novel microcapsules applied to self-healing composites. The microcapsules were synthesized by In-situ polymerization technology with poly(urea-formaldehyde) (PUF) as a shell material and dicyclopentadiene (DCPD) as core materials. The effect of processing parameters on the microcapsule's performance was analyzed. The chemical structure of microcapsule was characterized using fourie-transform infrared spectroscopy (FTIR), Morphlogy and shell wall thickness of microcapsule were observed using scanning electron microscopy (SEM). The thermal properties and the stability were analysis using thermal gravity analysis (TGA). The results indicate that PUF microcapsules containing DCPD can be synthesized successfully.
