Polycaprolactone(PCL)/열가소성전분 복합체의 물성 및 퇴비화법에 의한 생분해도 연구
A Study on the Properties and Biodegradability Polycaprolactone(PCL)/Thermoplastic starch composite Under Controlled Composting Conditions
Blends was prepared from polycaprolactone(PCL)/Thermoplastic starch(TPS). Mechanical properties, thermal property, water absorption, biodegradability by composting were investigated. Strength and elongation at break decreased as the content of TPS increased, but modulus increased until the content of TPS was 30% and comparatively maintained after that. The glass transition temperature of PCL and TPS was not changed as composition. The water absorption and biodegradability increased as the content of TPS increased.
