| 摘要:近年来，膜分离技术凭借其高效低耗、工艺简单等优势逐渐取代传统的物化手段，成为油水分离的最佳选择。但是目前膜分离材料存在稳定性较差、不可降解、易受污染、分离体系单一等不足；因此，研究一种绿色环保、具有特殊功能的环境响应性材料成为当前趋势。本文综述了pH值、温度、光等外部环境刺激条件下，超浸润性纤维素基油水分离膜的最新研究进展；详细分析了其制备原材料、制备工艺、改性方法和环境对超浸润性纤维素膜的抗污性、稳定性和油水分离效果的影响，并指出了其在油水分离领域中存在的潜在问题和未来应用前景。 |
| Abstract:In recent years， membrane separation technology has gradually replaced traditional physicochemical due to its advantages of high efficiency， low consumption and simple process， and has become the best choice for oil-water separation. However， the current membrane separation materials have shortcomings such as poor stability， non-degradability， susceptibility to pollution， and single separation system. Research on a green， environmentally friendly， environmentally responsive material with special functions has become a current trend. The latest research progress of super-wetting cellulose-based oil-water separation membranes under external environmental stimuli such as pH value， temperature， and light was reviewed in this paper. The effects of its preparation original material， preparation process， modification method and various environments on the antifouling， stability and oil-water separation effect of the cellulose membrane were analyzed in detail. Its potential in the field of oil-water separation was pointed out and the problems and future application were prospected. |
