摘要: 研究了静电纺工艺条件对聚乙烯醇(PVA)纳米纤维毡力学性能的影响。结果表明,随电压升高,静电纺PVA纳米纤维毡的断裂伸长率先增加后降低,断裂强度逐渐增加;随着喷丝口与接收屏之间距离的增加,静电纺PVA纳米纤维毡的断裂伸长率和断裂强度先增加,然后迅速下降;随着纺丝液质量分数的升高,静电纺PVA纳米纤维毡的断裂伸长率增加,断裂强度先下降,然后迅速升高。

Abstract: The effect of electro-spinning technology to the mechanical properties of nanometer poly(vinyl alcohol)(PVA) fiber mat was researched.The results show that with the rising of voltage,the breaking elongation rate of the electro-spun nanometer PVA fiber mat first increases,then goes down,and the breaking strength increases gradually;the breaking elongation rate and breaking strength first increase,and then drop rapidly as the distance between the spinneret and the receiving screen increases;the breaking elongation rate increases and the breaking strength drops a little at the beginning,and then increases rapidly as the concentration of the spinning solution increases.
