제목 Fabrication and Characterization of Poly(Urea-Formaldehyde) Microcapsule Containing PDMS/Pt for Self-Healing Process
초록 This study presents the poly (urea-formaldehyde) microcapsules containing poly (dimethyl siloxane) (PDMS) or Platinum (Pt) catalyst for self-healing process. Self-healing polymers and composite that integrate microencapsulated healing agent possess excellent healing efficiency in response to damage in host material. When the physical damage is applied to host material and rupture of microcapsule occurs, PDMS and Pt catalyst can meet and Pt-catalyzed hydrosilylation of PDMS proceed, so the self-healing process starts. In this study, microcapsules were prepared by in-situ polymerization via an oil-in-water (O/W) emulsion. The size of microcapsule could be controlled from 100 to 250um by changing the agitation speed. The microcapsules containing healing agent and catalyst were applied to epoxy and polyurethane (PU) resin and their self-healing efficiency in response to damage was successfully demonstrated.
