PDMS/PVDF静电纺丝膜的制备及油水分离性能研究
Preparation and oil-water separation performance of PDMS/PVDF electrospun membranes
摘要
Abstract
The PDMS/PVDF membranes with a special wetting surface were prepared for oil-water separation by using an electrospinning technology.The effect of mass ratio of PVDF to PDMS on the membrane-forming performance was investigated.The results indicated that an appropriate amount of PVDF could generate a spinning and plasticizing effect on PDMS,and the presence of microspheres resulted in better hydrophobicity for the membranes compared to those with-out microspheres.Furthermore,the membranes exhibited a high adhesion to water due to a capillary force and electro-static interactions.When the mass ratio of PVDF to PDMS was 2∶1,the membranes showed the optimal hydrophobicity with a water contact angle up to 150 ° and an oil contact angle closed to 0 °.The separation rate of the membranes for wa-ter-in-oil emulsions was more than 98%.This makes the membranes developed in this work a good candidate as an oil-water separation material.关键词
