摘要
制备了聚乳酸/改性淀粉复合材料及发泡材料,研究了聚乳酸/淀粉复合体系的相容性及流变性能.结果表明,糊化改性淀粉与聚乳酸具有较好的相容性,改性淀粉与聚乳酸复合材料具有较好的熔体粘弹行为,淀粉糊化改性后,复合材料的发泡性能得到优化,吸水性大大降低。
PLA/modified starch composites and foams were prepared by extrusion. The compatibility and rheological property of PLA/starch composites were researched. As shown, PLA/gelatinized starch had better compatibility and viscoelasticity. The results of foam performance showed that foam performance tended to be excellent after starch was gelatinized, and water absorption could be decreased remarkably.
