Fabrics have been used broadly in daily life for an enormous variety of applications due to their intrinsic advantages, such as flexibility, renewability, and good processability. Integrating natural fabrics with metal–organic frameworks (MOFs) is an effective strategy to improve the added value of textiles with special functionalities. Here, a facile, low-cost, and scalable technology is reported for the in situ growth of MOFs on cotton fabrics. A uniform and dense coating of regular octahedral Cu-1,3,5-benzenetricarboxylic acid (CuBTC) crystals was formed on the fiber surface, followed by treatment with 1H,1H,2H,2H-perfluorooctyltriethoxysilane and triethoxyoctylsilane to create a superhydrophobic CuBTC@cotton fabric (SMCF), which greatly improved its water stability and extended superhydrophobic CuBTC’s potential applications. The as-prepared MCF has a specific surface area of 229 m2/g, which is 11 times that of pristine fabrics (21 m2/g). This high porosity further endows the fabric with enhanced loading capacity of essential oils to enable excellent antibacterial ability. Moreover, the SMCF also exhibits excellent self-cleaning, UV shielding, and anti-icing performances. In addition, we performed COMSOL simulations to investigate the dynamic freezing process of water on the surface of samples, which agrees well with our experimental observations. By combining the merits of both fabrics and MOFs, the MCF is expected to extend the applications of traditional textiles in antifouling, safety, the fragrance industry, and healthcare for the next-generation multifunctional fabrics.

通过用于多功能应用的逐层策略在柔性织物上原位生长稳定的金属有机框架 (MOF)
织物由于其固有的优势，如柔韧性、可再生性和良好的加工性，已在日常生活中广泛用于各种各样的应用。将天然织物与金属有机框架 (MOF) 相结合是提高具有特殊功能的纺织品附加值的有效策略。在这里，报告了一种简便、低成本且可扩展的技术，用于在棉织物上原位生长 MOF。在纤维表面形成均匀致密的规则八面体 Cu-1,3,5-苯三甲酸 (CuBTC) 晶体涂层，然后用 1 H ,1 H ,2 H ,2 H处理-全氟辛基三乙氧基硅烷和三乙氧基辛基硅烷共同制备超疏水CuBTC@棉织物（SMCF），极大地提高了其水稳定性并扩展了超疏水CuBTC的潜在应用。制备的MCF比表面积为229 m 2 /g，是原始织物（21 m 2/G）。这种高孔隙率进一步赋予织物增强的精油负载能力，从而实现出色的抗菌能力。此外，SMCF 还具有优异的自清洁、紫外线屏蔽和防冰性能。此外，我们进行了 COMSOL 模拟来研究水在样品表面的动态冻结过程，这与我们的实验观察结果非常吻合。通过结合织物和 MOF 的优点，MCF 有望将传统纺织品在防污、安全、香水工业和医疗保健领域的应用扩展到下一代多功能织物。
