Optimization of microencapsulation process for self-healing polymeric material

Optimization of microencapsulation process for self-healing polymeric material

A series of poly(urea-formaldehyde) (PUF) microcapsules filled with dicyclopentadiene (DCPD) was successfully prepared by in situ polymerization. The effect of diverse process parameters and ingredients on the morphology of the microcapsules was observed by SEM, optical microscopy (OM) and digital m...
