摘要:

对大豆分离蛋白(SPI)/聚乙烯醇(PVA)的电纺进行了研究, 讨论了溶液性质和甘油的加入对SPI/PVA电纺纤维形貌的影响, 并对SPI/PVA电纺膜进行了成分分析和力学性能表征. 结果表明, 加入甘油可以提高SPI/PVA的可电纺性, 同时使SPI/PVA电纺膜的拉伸强度从不含甘油的(5.17±0.62) MPa下降到含有甘油的(1.67±0.21) MPa, 而伸长率呈增加趋势.

Abstract:

Electrospinning of soy protein isolate(SPI) in the presence of poly(vinyl alcohol)(PVA) was investigated in order to broaden applications of SPI. The effect of properties of SPI/PVA solutions and the glycerol addition on the morphology of electrospun fibers were discussed. Characterization and mechanical properties of electrospun SPI/PVA membranes were also analyzed. The results show that introduction of glyce-rol can improve the electrospinability of SPI/PVA. The tensile strength of electrospun SPI/PVA membranes decrease from (5.17±0.62) MPa to (1.67±0.21) MPa and the elongation show an increase tendency with increasing the amount of glycerol.
