Mechanical, Thermal and Morphological Properties of Poly(lactic acid)/Natural Rubber Nanocomposites

This paper reports a melt blend of poly(lactic acid)/liquid natural rubber with Cloisite C30B (C30B). The mechanical, thermal and morphological properties of poly(lactic acid)/liquid natural rubber and nanocomposites were investigated. Results indicate that Young’s modulus and flexural modulus incre...
