Abstract

Natural fiber reinforced polymer (NFRP) composites were prepared by a twin screw extruder to investigate the effect of metal oxides on the odor improvement that occurs during the manufacture of NFRP in polypropylene (PP). Kenaf fibers, bamboo fibers and cellulose nano fibers (CNF) were used as natural fibers, and in the case of metal oxides, copper oxides and manganese oxides were used alone or mixed. Component analysis of volatile organic compounds was conducted by using gas chromatography-mass spectrometry (GC-MS) and electronic nose (Heracles II). In particular, principal component analysis (PCA) was conducted on furfural and major organic compounds, which are known as major odor components of NFRP composite. In addition, the influence of the metal oxide on the mechanical properties such as tensile, flexural, and impact properties of the PP/BF composite was investigated.


금속 산화물 적용이 폴리프로필렌(PP)에 천연 섬유가 강화된 복합체(natural fiber reinforced polymer, NFRP) 제조 시 발생하는 냄새 개선에 주는 영향을 고찰하기 위해 NFRP 복합체를 이축압출기를 이용하여 제조하였다. 천연 섬유로는 양마 섬유, 대나무 섬유 및 셀룰로오스 나노 섬유(CNF)가 사용되었으며, 금속 산화물로는 구리 산화물과 망간 산화물을 단독 또는 혼합 적용하여 사용하였다. 기체 크로마토그래피-질량분석기(gas chromatography-mass spectrometry, GC-MS)와 전자 코(electronic nose, Heracles II)를 통해 휘발성 유기 화합물에 대한 성분 분석을 실시하였으며, 특히 NFRP 복합체의 주요 냄새 성분으로 알려진 furfural과 주요 유기 화합물에 대해 주요 성분 분석(PCA)을 실시하였다. 또한, 금속 산화물의 적용이 PP/BF 복합체의 인장, 굴곡, 충격 특성 등의 기계적 물성에 미치는 영향을 고찰하였다.
