静电纺PVA纳米纤维毡的力学性能

Mechanical properties of electro-spun nanometer PVA fiber mat

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。

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 rapidly as the distance between the spinneret and the receiving screen strength first increases ; the increase, and then 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.
