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。 The use of magnetron sputtering and plasma treatment of non-woven fabric, can significantly improve the uniformity of the distribution of nanofibers; to further explore the plasma treatment of the substrate surface groups and conductivity, the results showed that the substrate surface Produce a lot of polar groups, conductivity increased, under the same spinning conditions and spinning time, so that the surface of the deposited fiber diameter becomes smaller, the amount of deposited fibers increases, but also further reduces the composite membrane pore size, pore size distribution more Concentrated, is conducive to the preparation of high efficiency, high-precision composite filter membrane.
