| 摘 要： | 利用一步溶液共混法，将预糊化的淀粉糊与PvA溶液共混，用乙二醛进行交联，制备淀粉／聚乙烯醇（PVA）完全生物降解塑料薄膜。研究不同乙二醛和甘油的用量对薄膜性能的影响。薄膜的力学性能、热性能和微观形态表征表明，淀粉／PvA体系具有较好的相容性和较高的力学性能，薄膜的拉伸强度和断裂伸长率分别可达到28．52MPa和307．5％。

| Abstract: | Fully biodegradable film of starch/poly(vinyl alcohol) was prepared via one-step solution mixing method, in which glyoxal was introduced directly into the mixture of pregelatinized starch paste and poly (vinyl alcohol) solution as a crosslinker. The effect of volume fraction of glyoxal and glycerin on plastic film's properties was studied. The starch/poly (vinyl alcohol) blend possessed better compatibility and higher mechanical properties. The film's tensile strength and elongation at break was 28. 52 MPa and 307.5 %, respectively. |
