为了研究静电纺工艺参数对含银PA6纳米纤维直径分布的影响,采用静电纺丝技术,在不同含银量、纺丝液质量分数、纺丝电压、接收距离(C-SD)、喷嘴直径条件下制备出含银PA6纳米纤维膜.利用扫描电镜(SEM)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0.2%～0.4%、纺丝液质量分数10%～16%、纺丝电压12～21kV、接收距离9～18cm、喷嘴直径0.5～1.2mm的实验范围内,纳米纤维的平均直径为70～90nm;纳米纤维直径随银溶胶质量分数的增加而减小,随纺丝液质量分数的增加而增大,随喷嘴直径的增大而增大;电压和接收距离对纳米纤维直径的影响较小.
In order to study the effect of electrospinning process parameters on the diameter-distribution of PA6nanofibers containing silver particles,the electrospinning technology is used to prepare the nanofiber.The nylon 6nanofiber membranes containing silver particles are prepared via electrospinning with different silver mass fraction,different spinning solution concentrations,different spinning voltage,different receiving distance(C-SD)and different nozzle diameter.The diameter-distribution and morphology of nanofibers containing silver particles are analyzed by scanning electronic microscope(SEM)and related software,the silver mass fraction of which is 0.2%～0.4%,the solution concentration is 10%～16%,the spinning voltage is 12～21kV,the receiving distance(C-SD)is 9～18cm,nozzle diameter is 0.5～1.2mm.The average diameter distributes from 70nm to 90nm.The diameter of nanofiber reduces as the content of silver particles increases,incresses as the solution concentration is raised and increases with the nozzle diameter iS raised.The voltage and receive distance(C-SD)have little influence on nanofiber diameter.
