纤维素基油水分离材料研究进展

石油泄漏事故及工业含油废水排放等严重破坏了人类赖以生存的生态环境，如何有效分离油水混合物成了当前的研究热点。传统的油水分离材料的不可回收性带来材料的二次污染极大限制了它们的广泛应用。纤维素是地球上最丰富的天然聚合物，并且具有生物相容性、生物降解性、化学稳定性和低成本等特点，因此纤维素基油水分离材料亦受到广泛关注。本文系统总结了近年来过滤型和吸附型纤维素基油水分离材料的研究进展，重点围绕纤维素类物质作材料基底（滤纸、棉布等）、用其进行表面改性（纤维素纳米晶体、纤维素衍生物等）以及全纤维素基油水分离材料等方面进行详细分析和介绍，对纤维素基油水分离材料存在的问题进行了探讨，并对其未来发展进行了展望。

Recent progress in cellulose-based materials for oil-water separation

Crude oil spill accidents and industrial oily wastewater discharge have severely damaged the eco-logical environment that humans rely on. How to effectively separate oil-water mixtures has become a current research hotspot. The non-recyclability of traditional oil-water separation materials causes secondary pollution of the materials, which greatly limits their wide application. Cellulose is the most abundant natural polymer on earth. It has the characteristics of biocompatibility, biodegradability, chemical stability and low cost, which makes cellulose-based oil-water separation materials have received extensive attention. This article systematically summarized the research progress of filtration and adsorption cellulose-based oil-water separation materials in recent years, focusing on detailed analysis of cellulosic materials as the substrates (filter paper, cotton cloth, etc.) and the coatings (cellulose nanocrystals, cellulose derivatives, etc.), and all-cellulose-based oil-water separation materials. Finally, the existing problems of cellulose-based oil-water separation materials are discussed with looking forward to their future development.
