摘要

制造一种具有显著阻燃性、抗紫外线（UV）和超疏水性的织物是一种简单而环保的织物，对多任务要求具有重要意义。在这方面，本文报道了一种在大麻织物（HF）上原位合成金属有机骨架（NH2-MIL-53(Al)）的无氟、简便和绿色方法，用于制备多功能纺织品。在HF表面沉积一层均匀致密的NH2-MIL-53（Al）晶体涂层，然后用三乙氧基辛烷（TEOS）改性得到超疏水NH2-MIL-53(Al)@麻织物（SM(Al)HF-9），显著提高了其水稳定性。SM(Al)HF-9具有优异的超疏水性，其水接触角（WCA）可达156°。此外，SM(Al)HF-9表面不能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，能有效分离水中的四氯甲烷和正己烷，分离效率超过97%。SM(Al)HF-9具有优异的防紫外线性能，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，其自熄能力和显著提高的极限氧指数（LOI）为32.4%。与原HF相比，改性HF的峰值放热率（PHRR）和总放热率（THR）分别降低了76.15%和54.32%。同时，NH2-MIL-53（Al）在提高HF的阻燃性方面比其他mof（如ZIF-67、Ce-MOF、Ag-MOF、Fe-MOF和MIL-53(Al)）有明显的优势。高效阻燃、抗紫外线、超疏水织物在家居、公共装饰、防火等领域具有广阔的应用前景。

Green fabrication of highly flame-retardant, anti-ultraviolet radiation and superhydrophobic cellulose-based fabric by constructing dualtielement-containing NH2-MIL-53(Al)@Triethoxyoctylsilane nano coatings

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 (NH₂-MIL-53(Al)) on hemp fabric (HF) for the preparation of multifunctional textiles. A homogeneous and compact coating of NH₂-MIL-53(Al) crystals was deposited on HF, followed by modification with triethoxyoctylsilane (TEOS) to manufacture superhydrophobic NH₂-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 NH₂-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.

期刊介绍： The International Journal of Biological Macromolecules is a well-established international journal dedicated to research on the chemical and biological aspects of natural macromolecules. Focusing on proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins, biological poly-acids, and nucleic acids, the journal presents the latest findings in molecular structure, properties, biological activities, interactions, modifications, and functional properties. Papers must offer new and novel insights, encompassing related model systems, structural conformational studies, theoretical developments, and analytical techniques. Each paper is required to primarily focus on at least one named biological macromolecule, reflected in the title, abstract, and text.
