Influence of Nucleating Agent on PLLA Crystalline and Mechanical Properties

Abstract:

This paper mainly concerned the effect of nucleating agents CAV101 on PLLA crystalline property. CAV101 was mixed with poly (L-lactic acid) (PLLA) to make PLLA/CAV101 blends, with CAV101 contents of 0, 0.1%, 0.3%, 0.5%, 0.7%, respectively. Mechanical performances, morphology and crystalline properties were investigated by tensile test, WAXD, SEM. The results demonstrated that the tensile strength and elongation of PLLA increased with the increase of CAV101 content and the maximum value at CAV101 of 0.3% and 0.5%, respectively. The crystallinity of PLLA blends CAV101 of 0.1%, 0.3%, 0.5%, 0.7% were 86.58%, 82.43%, 49.01%, 64.00% respectively.The SEM investigation found that the agglomeration of PLLA with the increasing of nucleating agents CAV101 content.
