초록

본 논문에서는 대나무 섬유(BF)의 화학처리가 BF 및 폴리프로필렌(PP)/대나무섬유(BF) 복합체의 물성에 미치는 영향을 고찰하기 위해, 알칼리 처리 전후의 BF에 대해 ${\gamma}$-aminopropyltriethoxysilane (APS), ${\gamma}$-glycidoxypropyl-trimethoxysilane (GPS) 그리고 ${\gamma}$-mercaptopropyltrimethoxysilane (MRPS)을 이용하여 실란 상용화제를 처리하였다. BF의 화학처리에 따른 형태학적 특성은 광학현미경(OM)과 주사전자현미경(SEM)을 통해 확인하였으며, 화학 구조의 변화는 FT-IR과 EDS를 통해 확인하였다. 실란처리 시 BF의 열안정성이 증가함을 TGA를 통해 확인하였다. 실란 처리한 PP/BF 복합체의 굴곡강도와 충격특성이 개선되는 것을 만능시험기(UTM)와 충격강도시험기(Izod impact test)를 통해 확인하였고, PP/BF 계면 접착특성이 개선되는 것을 인장시험 후 시편의 파단면을 SEM 사진을 통해 확인하였다.

In order to investigate the effect of the chemical treatment of bamboo fiber on physical properties of polypropylene (PP)/bamboo fiber (BF) composites, silane coupling agents such as ${\gamma}$-aminopropyltriethoxysilane (APS), ${\gamma}$-glycidoxypropyl-trimethoxysilane (GPS) and ${\gamma}$-mercaptopropyltrimethoxysilane (MRPS) were applied to BF and alkaline treated BF. Morphological properties of the chemically treated BF were confirmed by optical microscope and SEM measurements, and chemical structure changes were confirmed by FT-IR and EDS. TGA results showed that the thermal stability of silane treated BF increased. Based on the analysis of a universal testing machine and an Izod impact test, the flexural and impact properties of PP/silane treated BF composites showed higher values than those of PP/BF composites. The enhancement of interfacial adhesion properties of the PP/BF composite was checked from SEM images of the fracture of specimens after the tensile test.
