摘要
以聚偏氟乙烯(PVDF)粉末为原料,将N,N-二甲基甲酰胺与丙酮按体积比8∶2配制成含量和黏度可控的纺丝液,用静电纺丝法制备了PVDF超疏水纳米纤维膜。利用扫描电子显微镜和图像分析软件对所制纳米纤维膜的形貌、孔径分布及孔隙率、表面接触角、纯水通量等进行分析,考察了纺丝液含量、施加电压、接收距离、纺丝速度对超疏水纳米纤维膜的影响。结果表明,在纺丝液含量为10%(质量分数)、施加电压为18kV、接收距离为15cm、纺丝速度为1.0mL/h条件下,通过连续静电纺丝制备的超疏水纳米纤维膜具备最优的防水效果。
Polyvinylidene fluoride(PVDF)powder was used as raw material,and N,N-dimethylformamide and acetone were prepared into a spinning solution with controlled content and viscosity at volume ratio of 8∶2.PVDF superhydrophobic nano-particles were prepared by electrospinning method.The morphology,pore size distribution,porosity,surface contact angle and pure water flux of prepared nanofiber membrane were analyzed by scanning electron microscopy and image analysis software.The content of spinning solution,the applied voltage,the receiving distance and spinning speed were investigated.The results showed that under the condition of the spinning solution content of 10%(mass fraction),the applied voltage of 18 kV,the receiving distance of 15 cm and the spinning speed of 1.0 mL/h,continuous static electricity was passed.The superhydrophobic nanofiber membrane prepared by spinning had the best waterproof effect.
