以木质素为共混聚合物,对聚乳酸进行改性.制备出不同比例的复合材料,并对不同的复合材料进行一系列的力学性能表征.结果表明,虽然两者为不完全相容体系,但木质素可以在一定程度上提高聚乳酸的力学性能,并且当两者比例为8:2时改性效果最佳.
With lignin as polymer blends of poly lactic acid was modified. Preparation of composite materials with different proportion, and characterized by a series of mechanical properties of different composites. The results show that although the two incompatible system, but can improve the mechanical properties of lignin poly lactic acid in a certain extent, and when the ratio of 8:2 when the modification effect is the best.
