Abstract

In this study, the effects of heat treatment on the physical properties of polypropylene (PP) composites with bamboo fiber (BF) treated by silane coupling agent were investigated. The silane coupling agent was (3-mercaptopropyl) trimethoxysilane (MRPS). Heat treatment (curing step) at 25, 80, 110, 130, 150, and 170 ℃ was applied to induce chemical bonding between the hydroxyl group (-OH) present on the surface of BF and the hydroxyl group (-OH) of the hydrolyzed silane. The chemical structures of BF were analyzed by FTIR and XPS. The thermal stability, tensile and flexural strength were improved after applying heat treatment, and the optimum results were obtained when the heat treatment temperature was the range of 110-130 ℃.


본 연구에서는 실란 커플링제로 처리된 대나무 섬유(bamboo fiber, BF)를 포함하는 폴리프로필렌(polypropylene, PP) 복합체의 물성에 미치는 열처리 영향을 고찰하였다. 실란 커플링제로는 (3-mercaptopropyl)trimethoxysilane (MRPS)이 이용되었으며, 실란 처리 후 BF의 표면에 존재하는 수산기와 가수분해된 실란의 수산기 사이의 화학적 결합을 유도하기 위해 25, 80, 110, 130, 150, 170 ℃에서 열처리(curing step)를 진행하였다. 실란처리 후 BF의 화학구조 변화는 FTIR과 XPS를 이용하여 분석하였으며, 열처리된 PP/BF 복합체의 경우 열안정성 및 인장, 굴곡 강도등이 개선되었으며, 특히 열처리 온도가 110-130 ℃일 때 개선 정도가 우수하였다.
