摘要:

以聚乙烯醇为原料进行静电纺丝,观察静电纺过程中射流形态和纳米纤维在接收装置上的沉积形态,并采用扫描电镜观察纳米纤维的形态。分析了溶液质量分数及其导电性和施加电压这3个参数对射流运动所形成的锥形包络轨迹的顶角、纳米纤维在接受装置上的沉积面积和纳米纤维直径的影响。研究发现:锥形包络轨迹的顶角和纳米纤维的沉积面积随着这3个参数增加而减少;纤维直径随着溶液质量分数的增加而增加,随着溶液导电性的增加而减少,随着施加电压的增加先增加再减少。

Abstract:

Electrospinning method was used to fabricate PVA nanofibers. The effects of solution mass concentration, conductivity and applied voltage on the vertex angle of envelope cone formed by exactly rapid moving jet, nanofiber deposited area and average diameter were investigated by a digital camera and SEM. The results indicated that the angle and the area decreased with the increase of these parameters. Fiber diameter increased with the increase of solution mass concentration, decreased with the increase of solution conductivity and increased firstly with the increase of applied voltage, and then decreased.
