摘要
采用磁控溅射和等离子体技术处理非织造布,可以明显地改善纳米纤维分布的均匀性;进一步探讨了等离子体处理后对基材表面基团及导电性的影响,结果显示为基材表面产生很多极性基团、导电性增强,相同纺丝条件及纺丝时间下,使其表面沉积的纤维直径变小、沉积的纤维数量增加,也进一步减小了复合膜的孔径、孔径分布更加集中,有利于制得高效率、高精度的复合过滤膜。
Electrospinning nanofiber layers should use melt-blown nonwoven or spun-bond nonwoven as supporting material,due to lack of self-supporting mechanical strength when used for filters. Because of the collecting substrates＇ bad conductivity,there were some effects on nanofibers distribution and forming inelectrospinning. The magnetron sputtering and plasma technology were used to treat the nonwovens, which can obviously improve the distributing uniformity of the nanofibers. Through further exploring the influence on the surface chemical groups andconductivity of the collecting sub- strate by plasma technology treated. The results showed that there were many polar groups on the surface of the substrate, and the conductivity of it was enhanced. With the same electrospinnig conditions and time, the fibers＇ diameter was reduced on the surface of the collection, and the amount of the fibers was increased. The aperture of the composite was reduced and the pore size distribution was more centralized, which was helpful to make high efficiency and high precision composite ill- tration.
