静电纺丝制备PAN/CNTs复合纤维及其VOCs吸附性能研究
Preparation of PAN/CNTs Composite Fibers by Electrospinning and Study on Their VOCs Adsorption Properties
摘要
Abstract
Nanofibers have the advantages of high strength,high specific surface area,ultra-fine size,high flexibility and biocompatibility,and are widely used in various fields.Polyacrylonitrile/carbon nanotube(PAN/CNTs)composite nanofibers with adsorption function for volatile organic compounds(VOCs)were prepared based on electrospinning technology.By optimizing the experimental parameters,such as spinning solution concentration,spinning voltage and receiving plate distance,the most suitable combination of parameters for PAN fibers in the electrospinning process was explored.The results show that when the concentration of spinning solution is 12%,the spinning voltage is 18 kV.When the distance between the receiving plates is 14 cm,the morphology of PAN fibers is regular,the size is uniform,and the average diameter is 200 nm.After the addition of CNTs,the fiber diameter increases to 400 nm,but the structure of PAN does not change.When the content of CNTs is 3%,the morphology of the fibers is the best.The adsorption experiment of VOCs shows that the adsorption efficiency of PAN fiber membrane for xylene gas increased to about 90%by the introduction of CNTs.关键词
