中文摘要：利用三水溴化锂熔盐对剑麻纤维进行凝胶化,并通过硅酸四乙酯(TEOS)与十六烷基三甲氧基硅烷(HDTMS)的水解与缩聚反应制备了一种纤维素基多孔膜,利用SEM、FTIR、XPS对材料的物理、化学结构进行了表征,探究了材料的润湿性及油水分离性能。结果表明,改性后纤维素膜的水接触角从21°提高至135°,油接触角接近于0°,体现出良好的油水吸附选择性,可净化含油水体;疏水膜对蒸馏水、橙汁、椰奶、菊花茶、酱油、咖啡、番茄汁、染料水溶液、番茄酱等常见生活污水、污渍具有良好防污效果;利用水流的冲击可以实现对固体污渍的快速自清洁。改性剑麻纤维膜在油水分离、防污及自清洁等方面的应用潜力,为环境净化和废水处理提供了一种可持续的高效解决方案。

外文摘要：The defibrillation capability of lithium bromide trihydrate molten salt was used to gelatinize the fibers and a cellulose-based porous membrane was obtained through the hydrolysis and polycondensation reactions of tetraethyl orthosilicate(TEOS)and hexadecyltrimethoxysilane(HDTMS).The physical structure and chemical properities of the material were characterized by using SEM,FTIR,and XPS,and its wettability and oil-water separation performance were investigated.The results showed that the water contact angle of the modified cellulose membrane increased from^(2)1°to 135°,while the oil contact angle approached 0°,indicating excellent oil-water adsorption selectivity and efficient purification of oily water.The hydrophobic membrane exhibited good antifouling properties against common household wastewaters and stains such as distilled water,orange juice,coconut milk,chrysanthemum tea,soy sauce,coffee,tomato juice,dye solutions,and ketchup.Additionally,the membrane demonstrated rapid self-cleaning of solid stains when subjected to water flow impact.This study highlights the potential of the modified sisal fiber-based porous membrane for effective oil-water separation and antifouling applications,providing a sustainable and efficient solution for environmental cleanup and wastewater treatment.
