Abstract

Copper oxide and manganese oxide, which are a kind of metal oxide catalyst, are melt-mixed using a twin screw extruder in a PP/BF composite to reduce the odor generated during the production of polypropylene (PP)/bamboo fiber (BF) composites. Olfactometry evaluation was performed to determine the odor level when copper and manganese oxide were applied to PP/BF composites alone or in combination. Component analysis was performed by GC-MS and electronic nose. In particular, the principal component analysis (PCA) was conducted for furfural and major organic compounds, which are known as major odor components of bamboo fiber composites. In addition, the effect of the application of metal oxides on the mechanical properties such as tensile, flexural, and impact properties of PP/BF composites was investigated.


폴리프로필렌(polypropylene, PP)/대나무 섬유(bamboo fiber, BF) 복합체의 제조 시 발생하는 냄새 개선을 위해 금속 산화물 촉매의 일종인 구리 산화물과 망간 산화물을 PP/BF 복합체에 이축압출기를 이용하여 용융혼합 방법으로 혼합 적용하였다. 관능적 평가를 통해 PP/BF 복합체에 구리와 망간 산화물을 단독 또는 혼합 적용되었을 때 냄새 수준을 측정하였고, GC-MS와 전자 코(electronic nose, Heracles II)를 통해 휘발성 유기화합물에 대한 성분 분석을 실시하였다. 특히 대나무 섬유 복합체의 주요 냄새 성분으로 알려진 furfural과 주요 유기화합물에 대해 주요성분분석(PCA)을 실시하였다. 또한 금속산화물의 적용이 PP/BF 복합체의 인장, 굴곡, 충격 특성 등의 기계적 물성에 미치는 영향을 고찰하였다.
