Abstract

In recent years, intelligent response membrane materials have aroused considerable interest in controllable oil–water separation. However, challenges such as unstable response repeatability and easy bacterial contamination continue to hinder their effective use. Herein, a superhydrophobic fabric with pH responsiveness and antibacterial property were synthesized by combing (3-mercaptopropyl)trimethoxysilane with AgNPs and pH-responsive polymer on a fabric substrate. The fabric persisted superhydrophobicity with a WCA of 156° under natural conditions, while underwent a controlled transition of surface wettability in acidic environments. Heavy oil–water mixtures and light oil–water mixtures achieved controllable separation both before and after pH response. The fabric exhibited outstanding oil–water separation capability, achieving a separation efficiency of 98.0% and a separation flux of up to 11,025.0 L·m⁻²·h⁻¹. The pH response and oil–water separation demonstrated excellent repeatability. Specially, the pH responsiveness was maintained for up to 10 cycles, and the oil–water separation remained repeatable for up to 15 cycles. Even when tested under various environmental conditions, the superhydrophobicity was retained. Additionally, the fabric possessed remarkable antibacterial property with an efficiency reaching 90.4%. The preparation of the superhydrophobic fabric serves as a valuable reference for developing multifunctional and stable intelligent materials for oil–water separation.

基于AgNP/共聚物复合材料的可控油水分离ph响应超疏水织物

近年来，智能响应膜材料在油水可控分离方面引起了广泛的关注。然而，诸如不稳定的反应可重复性和易细菌污染等挑战继续阻碍其有效使用。在织物衬底上，将（3-巯基丙基）三甲氧基硅烷与AgNPs和pH响应聚合物结合，合成了具有pH响应性和抗菌性能的超疏水织物。织物在自然条件下保持超疏水性，WCA为156°，而在酸性环境下，织物的表面润湿性发生了受控转变。稠油-水混合物和轻油-水混合物在pH响应前后均实现了可控分离。该织物具有优异的油水分离性能，分离效率达98.0%，分离通量高达11025.0 L·m−2·h−1。pH响应和油水分离具有良好的重复性。特别的是，pH响应性可维持10次循环，油水分离可重复进行15次循环。即使在各种环境条件下进行测试，超疏水性仍然保持不变。此外，织物具有显著的抗菌性能，抗菌效率达90.4%。该超疏水织物的制备为开发多功能、稳定的油水分离智能材料提供了有价值的参考。图形抽象

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
