Abstract

Multifunctional cotton fabric holds great promise across domestic and healthcare sectors. However, the challenge lies in developing a simple, sustainable method to create versatile, multifunctional cotton fabric. Herein, we designed novel 3D bimetallic organic frameworks (Ag/MIL125-NH₂) for the first time and fabricated BM125@COT, a superhydrophobic cotton fabric adorned with porous hierarchical grooves. This was achieved by spraying Ag/MIL125-NH₂ onto the cotton fabric's surface, followed by post-synthetic treatment with non-fluorinated myristic acid, resulting in superhydrophobic BM125@COT. The coated fabric showed a water contact angle (WCA) of 162.2° and a water sliding angle (WSA) of 4° ± 1. Surface morphology, size, structural and chemical composition, and anti-wetting properties of synthesized MOFs and BM125@COT were evaluated by SEM, EDS, TEM, XRD, XPS, UV/Vis, ATR, DSC, and Optical Tensiometer. Durability tests, including splash tests, abrasion resistance, tape peeling, washing, pH effects, and ultrasonication cycles, underscored the fabric's robust mechanical stability and chemical resistance. Moreover, superhydrophobic BM125@COT demonstrated UV-blocking efficiency, impressive self-cleaning capabilities, and enhanced antibacterial activity. This low-cost, scalable, and sustainable fabric, fabricated through a straightforward one-step spray coating technique, holds immense potential for versatile applications.

在棉织物上方便、可扩展地生长双金属三维 Ag/MIL125-NH2 以实现多方面的防湿和自愈特性

多功能棉织物在家用和医疗保健领域大有可为。然而，开发一种简单、可持续的方法来制造多功能棉织物是一项挑战。在此，我们首次设计了新型双金属有机框架（Ag/MIL125-NH2），并制成了 BM125@COT，一种装饰有多孔分层沟槽的超疏水棉织物。这是通过在棉织物表面喷涂三维双金属 MOF，然后用非氟化肉豆蔻酸进行后合成处理而实现的，从而得到了超疏水的 BM125@COT，其水接触角（WCA）为 162.合成的 MOFs 和 BM125@COT 的表面形貌、尺寸、结构和化学成分以及防湿性能通过 SEM、EDS、TEM、XRD、XPS、UV/Vis、ATR、DSC 和光学张力计进行了评估。耐久性测试（包括飞溅测试、耐磨性、胶带剥离、水洗、pH 值影响和超声波循环）强调了织物强大的机械稳定性和耐化学性。此外，超疏水 BM125@COT 还具有紫外线阻隔效率、出色的自清洁能力和更强的抗菌活性。这种低成本、可扩展、可持续的织物是通过简单的一步喷涂技术制成的，具有巨大的多功能应用潜力。我们的新型双金属 MOF 的致密涂层增强了润湿稳定性，极大地拓展了织物的商业前景。

期刊介绍： The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
