Abstract The sustainable development of membrane separation technology is facing the severe challenge of membrane fouling problem. This paper proposed a novel strategy that combined nanoimprint lithography and nanoparticle grafting technology to fabricate antifouling polyvinylidene fluoride membranes. The nanoimprint process brought about a wave-like micro-scaled surface pattern with alternate concave and convex structures. The subsequent grafting process with amine-terminated nanoparticles further decorated the pattern into a hierarchically structured surface, which allowed a rapid (

通过纳米压印和纳米粒子接枝制备的具有分级表面结构的超亲水聚偏二氟乙烯膜

摘要 膜分离技术的可持续发展面临着膜污染问题的严峻挑战。本文提出了一种将纳米压印光刻和纳米粒子接枝技术相结合的新型聚偏氟乙烯防污膜制备策略。纳米压印工艺产生了具有交替凹凸结构的波浪状微尺度表面图案。随后与胺封端的纳米粒子的接枝过程进一步将图案装饰成分层结构的表面,这允许快速(
