Abstract

Superhydrophobic materials are highly promising for diverse applications including self-cleaning, oil-water separation, anti-corrosion, flame retardancy, and resistance to frost and ice accumulation. However, their limited mechanical durability is a critical limitation impeding their broader industrial applications. In this study, a superhydrophobic synthetic diamond/UIO-66-(OH)₂/epoxy/PDMS (DUEP) composite coating was developed by spraying synthetic diamond/UIO-66-(OH)₂/PDMS suspension onto an aluminum sheet (AlS) pre-coated with epoxy resin, which exhibited excellent self-cleaning, antifouling capabilities, UV resistance, good chemical stability, high mechanical stability, excellent anti-frosting/icing performance. In addition, the superhydrophobic stainless steel mesh (DUEP-SM) was fabricated by spraying DUEP suspension onto the stainless steel mesh surface, which retained excellent oil/water separation performance for dichloromethane and dichloroethane. The superhydrophobic cotton fabric (DUEP-CF) was fabricated by immersing the cotton fabric into DUEP suspension, which had outstanding flame-retardant performance. The DUEP composite coatings are multifunctional and possess the capacity for extensive applications.

坚固的多功能超疏水合成金刚石/UIO-66-(OH)2/环氧树脂/PDMS涂料，用于油水分离，阻燃和防冰

超疏水材料在自清洁、油水分离、防腐、阻燃、抗霜冻和积冰等方面具有广阔的应用前景。然而，它们有限的机械耐久性是阻碍其更广泛工业应用的关键限制。本研究通过在预涂环氧树脂的铝板上喷涂合成金刚石/UIO-66-(OH)2/环氧树脂/PDMS悬浮液，制备了超疏水合成金刚石/UIO-66-(OH)2/环氧树脂/PDMS （DUEP）复合涂层，该涂层具有优异的自洁、防污、抗紫外线、良好的化学稳定性、高的机械稳定性和优异的抗结霜/结冰性能。此外，通过在不锈钢网表面喷涂DUEP悬浮液制备了超疏水不锈钢网（DUEP- sm），对二氯甲烷和二氯乙烷保持了优异的油水分离性能。将棉织物浸泡在DUEP悬浮液中制备超疏水棉织物（DUEP- cf），该悬浮液具有优异的阻燃性能。DUEP复合涂料具有多种用途，具有广泛的应用前景。

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
