摘　　要：对香蕉假茎加溶剂液化,液化物香蕉假茎基多元醇(BP)与聚醋酸乙烯酯乳液(PVAc)共混制备了一种BP/PVAc薄膜材料;研究了固化条件对共混膜性能的影响;通过拉伸试验、热重分析仪及扫描电子显微镜考察了共混薄膜材料的力学性能、热性能以及断面形貌。结果表明,掺杂BP会提高PVAc的断裂伸长率、柔韧性及耐水性。当BP/PVAc质量比大于1∶10时,制备的BP/PVAc共混薄膜在水中可以保持64 d结构不发生破坏。The objective was to develop processes for liquefaction of banana pseudo-stem and explore the potential of preparing polymer vinyl acetate（ PVAc） membrane from the liquefied banana pseudo-stem（ BP）. Methods including FTIR,TGA and SEM were selected to analyze characteristics of liquefied product and BP / PVAc membranes. The results show that the elongation at break,flexibility and water resistant property are improved by blending BP with PVAc. When the charge ratio of BP / PVAc 〉10,the prepared membranes can be kept for 64 d without destroyed in the water.
