Abstract

The potential risk of perfluorinated compounds (PFCs) has significantly restricted the commercial application of amphiphobic surfaces in the fabrication of water- and oil- repellent fabrics. In this work, we present a novel fluorine-free amphiphobic fabric, featuring a hierarchical surface architecture comprising silica gel particles and a specially designed polymer coating. The obtained fabric showed a water contact angle of 156° and an olive oil contact angle of 125°. Furthermore, the fabric maintained a water contact angle above 150° after rigorous durability assessment including 1500 abrasion cycles and 12-h chemical corrosion test, demonstrating high robustness of the coating. Notably, the fabric exhibited comparable repellency to low-surface-tension liquids with the commercial fluorinated counterparts. This environmentally benign alternative, combining superior amphiphobicity with exceptional durability, presents a promising solution for diverse practical applications in protective textiles and outdoor apparels.

耐用双疏织物的无氟涂层设计

全氟化合物（PFCs）的潜在风险极大地限制了双疏表面在制造拒水和拒油织物中的商业应用。在这项工作中，我们提出了一种新型的无氟双疏织物，具有由硅胶颗粒和特殊设计的聚合物涂层组成的分层表面结构。所得织物的水接触角为156°，橄榄油接触角为125°。此外，经过严格的耐久性评估，包括1500次磨损循环和12小时的化学腐蚀测试，织物保持了150°以上的水接触角，证明了涂层的高坚固性。值得注意的是，这种织物对低表面张力液体的驱避性与商用氟化织物相当。这种环保的替代品，结合了优越的两疏性和卓越的耐用性，为防护纺织品和户外服装的各种实际应用提供了一个有前途的解决方案。

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
