Damaging such as fractures and scratches cause deterioration of mechanical strength, toughness, surface gloss, and barrier properties. In this study, diblock copolymer was synthesized via RAFT polymerization with self-healable block (PtB) with bulky urea and hard-domain block (P4VP) which forms micelles. Prepared block copolymer is blended into PtB matrix polymer with various ratio to form desired micellar structures, and the blends were cross-linked with hexamethylene diisocyanate (HDI). Prepared samples were analyzed by TEM, UTM, Rheometer, and others. This work was supported by the Ministry of Trade, Industry and Energy (No. 10067082). |
