聚乙烯吡咯烷酮/聚（乙烯-乙烯醇）共混膜的制备及其油水分离性能
Preparation of polyvinylpyrrolidone/poly(ethylene-co-vinyl alcohol) blend membranes and the oil/water separation performance
摘要
Abstract
PVP/EVAL-blend-membranes-were-prepared-by-blending-PVP-with-poly(ethylene--covinyl-alcohol)-(EVAL)-via-immersion-precipitation-and-were-used-to-separate-the-oil/water-emulsion.-The-chemical-structure,morphology,mechanical-performance-and-hydrophilicity-of-PVP/EVAL-blend-membranes-were-characterized-by-FTIR-ATR,scanning-electron-microsco-py,tension-test-and-water-contact-angle-measurement.-The-effect-of-PVP-content-on-the-separa-tion-performance-of-oil/water-emulsion-was-investigated.-The-results-indicate-that-PVP-content-had-a-distinct-effect-on-the-morphology-of-PVP/EVAL-membranes.-The-tensile-strength-and-elon-gation-at-break-of-PVP/EVAL-blend-membrane-with-10-wt%-(the-mass-percent-of-PVP-in-the-casting-solution)-PVP-were-1.88-and-1.34-times,respectively,of-that-of-pure-EVAL-membrane.-When-the-content-of-PVP-increased-to-4-wt%,oil/water-emulsion-flux-of-PVP/EVAL-blend-membrane-was-1.81-times-of-that-of-the-pure-EVAL-membrane.-The-rejection-ratio-was-92.2%,-slightly-higher-than-the-pure-EVAL-membranes.-When-the-content-of-PVP-increased-to-10-wt%,-the-flux-recovery-ratio-after-washing-increased-from-51%to-77.98%.关键词
