摘要
研究了聚乙二醇(PEG)用量对淀粉-聚乳酸(PLA)原位熔融接枝反应的影响以及淀粉/PLA可降解材料的力学性能和耐水性能。结果表明:PEG能有效地提高淀粉接枝率。PEG的加入,改善了淀粉与PLA的界面相容性和黏结效果,同时提高了淀粉/PLA材料的拉伸强度和耐水性能。
Discussed the effect of the amount of polyethylene glycol （PEG） on in-situ graft copolymerization of starch grafted poly lactic acid （PLA） and the mechanical properties and the water resistance of starch/ PLA degradable materials. The results showed that PEG could increase the grafting ratio of the starch. The adding of PEG, improve the interfacial compatibility and cohering effect of starch with PLA, so as to improve its tensile properties and water resistance.
