纺丝液配备方法对PS/PVP纳米纤维膜性能的影响
|
摘要
采用特殊的纺丝液配备方法,依靠新型的气泡静电纺丝技术,成功纺制出PS/PVP纳米纤维膜,并对纳米纤维膜的微观形态、亲水性能、强伸性能、平均孔径及空气流速进行测试与分析。结果表明:不同配备方法的纺丝液获得的纳米纤维膜的微观形态、亲水性能、强伸性能、平均孔径及空气流速不同。表面粗糙程度高、孔洞多、有凹槽的纳米纤维,其形成的纳米纤维膜的亲水性能优,断裂强度高,断裂伸长率低,平均孔径和空气流速增加。
With special preparation method of spinning solution, the PS/PVP nanofiber membranes were successfully obtained by the new bubble electrospinning technology. The microstructure, hydrophilicity, strength and elongation, average pore diameter and air velocity of the nanofiber membranes were tested and analyzed. The results showed that, the microstructure, hydrophilicity, strength and elongation, average pore diameter and air velocity of the nanofiber membranes obtained by spinning solutions with different preparing methods were different. The nanofiber membrane had good hydrophilic properties, high strength and low elongation at break, which made of nanofibers with higher surface roughness, more holes and grooves, and its average pore diameter and air velocity increased.
