多层静电纺PAN纳米纤维复合膜的制备及性能

Poly(acrylonitrile) nanofibrous composite membrane were prepared via electrospinning, using a rotating mandrel with nonwovens binded.The effect of nanofiber layer thickness on the filtration property of Poly(acrylonitrile) nanofiber composite membrane has been investigated. Poly(acrylonitrile) nanofibrous composite membrane were characterized and tested by use of FE-SEM and SX-L1050 filtration teste.Results show that the longer the electrospinning lasts，the more nanofibers can be coated on the nonwovens. Fiber packing density and thickness of nanofibrous membrane is increased while more nanofibers added on microfiber substrate.The efficiency and pressure drop increase as the nanofiber layer thickness increased，but the quality effect remain objectively unchanged.
