PVA/PLA複合材料の力学特性および水中崩壊性の評価

抄録

In agriculture, there is a demand for the development of biodegradable capsules to contain seeds and other materials. In this paper, the combined effects of poly (vinyl alcohol) (PVA) to poly (lactic acid) (PLA) were investigated as a function of their mechanical properties and disintegration in water to use as the biodegradable capsules. PVA/PLA composites prepared using a twin-screw extruder were molded to the JIS standard specimens by injection molding and subjected to characterization test. The results show the composition of PVA/PLA composites that exhibit excellent mechanical properties and disintegration in water.
