静电纺PAN纳米纤维复合膜的制备及性能

Poly(acrylonitrile) nanofibrous composite membranes were prepared via electrospinning, using a rotating mandrel binded with nonwovens.The effect of area weight of nanofibrous membranes on the filtration property of Poly(acrylonitrile) nanofibrous composite membranes were studied. Poly(acrylonitrile) nanofibrous composite membranes were characterized and tested by use of FE-SEM,tensile tester and SX-L1050 filtration tester.The results show that the diameters of nanofibers increase from 117nm to 352nm while the solution concentration rising from 6% to 12% and the the corresponding fiber mechanical property rising up first then down.Under the same solution concentration,the filtration efficiency and pressure drop increase and the quality effect decrease while the area weight of Poly(acrylonitrile) nanofibrous composite membrane increased.
