Epoxy-carbazole compositions. Part I. Compositions with 9-(2, 3-epoxypropyl) carbazole

Abstract

Compositions of low-molecular weight epoxy resin Ruetapox 0162 mixed with various amounts of 9-(2,3-epoxypropyl)carbazole (EPK) have been prepared and cured by isophorone diamine. Mechanical, thermal and photoluminescence properties of obtained materials were determined. It was found that low- molecular weight epoxy resin is an excellent dispersing matrix for carbazole groups, which secures suitable mechanical properties, low combustibility and high thermal stability of prepared materials. Moreover, it was observed that the addition of 10 wt. % of EPK improves compression strength by 15%, flexural strength by 33% and also slightly decreases water absorption. Thin film forming ability and optic properties, characteristic for isolated carbazole molecules (photoluminescence maxima at 352 and 368 nm), point at the possibility to use studied materials for light-emitting diodes (LED) construction.
