생분해성 지방족 폴리에스테르 복합체의 제조 및 특성
Preparation and Characterization of Biodegradable Aliphatic Polyester Composite
Polycaprolactone (PCL) has been blended with thermoplastic starch (TPS) which was prepared from corn starch with glycerol using twin-screw extruder. The mechanical, thermal and biodegradability of blends was examined. Differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) studies revealed that PCL/TPS blends are immiscible blend but the surface adhesion was very good. Biodegradability of blends increased with increasing TPS content.
