The facile and eco-friendly fabrication of a fabric with remarkable flame retardancy, anti-ultraviolet (UV), and superhydrophobic properties is of significant interest for multitask requirements. In this regard, herein, a nonfluorine, facile, and green method is reported for in situ synthesis of metal-organic frame (NH-MIL-53(Al)) on hemp fabric (HF) for the preparation of multifunctional textiles. A homogeneous and compact coating of NH-MIL-53(Al) crystals was deposited on HF, followed by modification with triethoxyoctylsilane (TEOS) to manufacture superhydrophobic NH-MIL-53(Al)@hemp fabric (SM(Al)HF-9), significantly enhancing its water stability. The SM(Al)HF-9 exhibited superior superhydrophobicity properties, with a water contact angle (WCA) up to 156°. Furthermore, the surface of SM(Al)HF-9 cannot be adhered by dye solution and powder, indicating its good self-cleaning and anti-fouling abilities. The SM(Al)HF-9, characterized by a porous structure, effectively separates tetrachloromethane and n-hexane from water mixtures with a separation efficiency exceeding 97 %. The SM(Al)HF-9 has excellent UV-blocking properties, and the UV protection factor is as high as 105.44. Encouragingly, the SM(Al)HF-9 exhibited outstanding flame retardancy, as demonstrated by its self-extinguishing capability and a substantially improved limiting oxygen index (LOI) of 32.4 %. In comparison to raw HF, the peak heat release rate (PHRR) and total heat rate (THR) of the modified HF are reduced by 76.15 % and 54.32 %, respectively. Meanwhile, the NH-MIL-53(Al) has a significant advantage over other MOFs (e.g., ZIF-67, Ce-MOF, Ag-MOF, Fe-MOF and MIL-53(Al)) in improving the flame retardancy of HF. The highly efficient flame-retardant, anti-UV, and superhydrophobic fabric is promising in home and public decoration, and fire protection fields.
制备一种具有卓越阻燃性、抗紫外线（UV）和超疏水性能的织物，以满足多任务需求，这一过程简便且环保，备受关注。在这方面，本文报道了一种非氟、简便且绿色的方法，用于在大麻织物（HF）上原位合成金属有机框架（NH-MIL-53(Al)），以制备多功能纺织品。NH-MIL-53(Al)晶体在HF上沉积形成均匀致密的涂层，随后用三乙氧基辛基硅烷（TEOS）进行改性，制备出超疏水的NH-MIL-53(Al)@大麻织物（SM(Al)HF-9），显著提高了其水稳定性。SM(Al)HF-9表现出优异的超疏水性能，水接触角（WCA）高达156°。此外，SM(Al)HF-9的表面不会被染料溶液和粉末附着，表明其具有良好的自清洁和防污能力。SM(Al)HF-9具有多孔结构，能有效从水混合物中分离四氯化碳和正己烷，分离效率超过97%。SM(Al)HF-9具有优异的紫外线阻挡性能，紫外线防护系数高达105.44。令人鼓舞的是，SM(Al)HF-9表现出出色的阻燃性，其具有自熄能力，极限氧指数（LOI）大幅提高至32.4%。与原始HF相比，改性HF的峰值热释放速率（PHRR）和总热释放速率（THR）分别降低了76.15%和54.32%。同时，在提高HF的阻燃性方面，NH-MIL-53(Al)比其他金属有机框架（如ZIF-67、Ce-MOF、Ag-MOF、Fe-MOF和MIL-53(Al)）具有显著优势。这种高效的阻燃、抗紫外线和超疏水织物在家庭和公共装饰以及防火领域具有广阔前景。
