摘要

超疏水涂层已被用于解决溢油污染水源和水资源短缺的问题。然而,超疏水涂层的使用寿命较短,限制了其广泛应用。在这项研究中,我们制作了一种新型的无氟、自愈合和超疏水涂层,该涂层由聚二甲基硅氧烷(PDMS)、聚多巴胺(PDA)改性的哈洛来石纳米管(HNT)和蜂蜡(BW)组成,可用于油/水分离和雾/水收集。其中,PDA 可稳定 HNT 在涂层中的分散,同时增强改性纳米粒子在织物表面的附着力。制成的涂层的水接触角为 163.1°,显示出优异的超疏水特性。超疏水涂层的油水分离效率超过 99.5%,雾水收集率达到 990 ~ 1208 mg cm-2 h-1 。由于 BW 的存在,涂层具有显著的自修复特性,只需短暂的加热处理,就能在 100 个磨损周期后恢复超疏水特性。因此,这种简便的策略在大规模制造多功能超疏水涂层方面具有巨大潜力。

Fluorine‐free, self‐healing, and superhydrophobic coating for efficient oil/water separation and fog‐water collection
Superhydrophobic coatings have been used to solve the problems of oil spills polluting water sources and water resource shortages. However, the short service life of superhydrophobic coatings limit their widely application. In this work, a novel fluorine‐free, self‐healing, and superhydrophobic coating composing of polydimethylsiloxane (PDMS), polydopamine (PDA) modified halloysite nanotubes (HNT), and beeswax (BW) are fabricated for oil/water separation as well as fog‐water collection. Herein, PDA stabilizes the dispersion of HNT in the coating, and meanwhile enhances the adhesion of modified nanoparticles on fabric surfaces. The as‐fabricated coatings occupied a water contact angle of 163.1°, demonstrating exceptional superhydrophobic characteristics. The superhydrophobic coating exhibited superior oil/water separation efficiency of over 99.5% and outstanding fog‐water collection rate of 990 ~ 1208 mg cm−2 h−1. Owing to the presence of BW, the coatings demonstrated remarkable self‐healing properties and can regain superhydrophobicity after 100 wear cycles with just a short heating treatment. Therefore, this facile strategy has great potential for large‐scale manufacturing of multifunctional superhydrophobic coatings.

期刊介绍: Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
