Transparent Epoxy resin toughened with In-situ azide-alkyne Polymerized Aliphatic Toughening agent |
| 초록 |
To improve the toughness of the epoxy resin while maintaining their transparency, a novel polymer, which has an aliphatic structure, is synthesized via in-situ azide-alkyne polymerization as a toughening agent. Because of the dissimilar kinetics of the epoxy system and click reaction, sequential curing process was designed. There in-situ toughened epoxy with about 10wt% content of in-situ toughener of poly(BAC/PCLDA) showed excellent increase of fracture toughness while the transmittance of epoxy system was maintained. The homogeneous phase for the fracture surface of in-situ toughened epoxies in SEM micrographs was quite different from the two-phase morphology for the conventional preformed polymer-toughened epoxy systems. |
