摘要
为研究含银聚酰胺6（PA6）纳米纤维的直径分布和性能，采用静电纺丝技术，制备不同含银量的PA6纳米纤维毡。利用扫描电镜及相关软件，分析纳米纤维直径分布及形态，在银溶胶质量分数为0．1％～0．4％、纺丝液质量分数为10％～16％的实验范围内，纳米纤维平均直径为70～90nm；纳米纤维直径随银溶胶质量分数的增加而减小，随纺丝液质量分数增多而增大。透射电镜（TEM）分析表明：纳米银在纤维中分布均匀，状态呈圆形或椭圆形。纳米银颗粒平均直径为11．9nm，所有颗粒沿纤维的中轴线排列，部分呈椭圆形颗粒的长轴与纤维轴向一致。随银溶胶质量分数的升高，其抗静电性能提高。
The nylon 6 nanofibre containing silver particles with different concentrations were prepared via electrospinning. The diameter distribution and morphology of nanofibres containing silver particles was analyzed by scan electric microscope, and it was found that when the silver mass fraction was in the range of 0.1% - 0.4% and the solution concentration was 10% - 16%, the average diameter distributed from 70 nm to 90 nm. The diameter of the nanofibre reduced as the content of silver particles increased and increased as the solution concentration raised. The TEM images indicated that the silver particles were well-distributed in the nanofibers, showing round or elliptical, and the average diameter was 11.9 nm. All particles arranged along the nanofiber central axis line, and the long axis of some elliptical particles was parallel to nanofiber central axis. The results showed that as the content of silver particles increased, the antistatic property obviously improved.
