초록
본 연구에서는 생분해성 재료인 미세결정셀룰로오스(MCC) 분말 표면에 아미노기를 가지는 실란 커플링제인3-aminopropyltriethoxysilane(APS) 및 trimethoxysilylpropyl modified polyethylenimine(TPPI)로 표면 개질하여 이산화탄소(CO2) 흡착 기능을 가지는 충전제를 제조하고, 저밀도 폴리에틸렌(LDPE)과 혼합하여 고분자 복합체를 제조하는 연구를 수행하였다. APS 및 TPPI에 의해 표면 개질된 MCC 분말의 CO2 흡착 기능은 열중량분석기(TGA)로 분석하였다. 또한 개질된 MCC를 충전제로 사용하여 LDPE/MCC 복합체를 제조하고, 복합체의 기계적 물성은 만능재료시험기(UTM), MCC와 LDPE 계면에서의 상용성은 주사전자현미경(SEM)으로 측정하였다. APS 및 TPPI로 개질된 MCC는 순수 MCC 충전제 분말보다 LDPE와 상용성이 더 높아서, 인장강도, 파단연신율 및 영률 모두 증가함을 알 수 있었다.
In this study, we modified biodegradable microcrystalline cellulose (MCC) powders with 3-aminopropyltriethoxysilane (APS) or trimethoxysilylpropyl modified polyethylenimine (TPPI) silane coupling agents, which have CO2 adsorbable amino groups. After silanization, surface treated MCC fillers were melt blended with low density polyethylene (LDPE) to prepare LDPE/MCC composites. The adsorption amount of CO2 on surface modified MCC powders was analyzed by thermogravimetric analyzer (TGA). Mechanical properties of composites were measured by universal testing machine (UTM), and the compatibility between MCC powders and LDPE were investigated at their interfaces by scanning electron microscope (SEM). MCC powders modified with APS or TPPI showed higher tensile strength, elongation at break and modulus due to higher compatibility with LDPE compared to pristine MCC filler powder.
