基于表面改性的高效油水分离膜材料研究现状
Research status and development trends of eefficient oil-water separation membrane materials based on surface modification technology
摘要
Abstract
With the enormous annual generation of oily industrial wastewater,achieving efficient oil-water separation has emerged as a critical challenge in addressing contemporary environmental pollution issues.Compared to traditional oil-water separation technologies,membrane separation technology based on surface modification has garnered significant attention in recent years due to its advantages of high selectivity,anti-fouling properties and sustainability.This paper systematically reviewed current research advances in oil-water separation membrane materials.Firstly,the multilevel collaborative restructuring of membrane/liquid interface behavior via the substrate surface modification,encompassing wettability modulation,charge introduction and microstructure/nanostructure optimization was explored.Subsequently,it was focused on four major substrate systems-metallic materials,synthetic polymers,biomass-derived materials and ceramics-providing an in-depth comparison of how structural characteristics and modification strategies affect separation performance.By analyzing representative case studies,the enhanced performance of surface-modified membranes in water flux,separation efficiency and stability was further elucidated.Finally,the persistent challenges in current research were identified followed by proposing future directions to advance the continuous development of oil-water separation technologies.关键词
