Abstract：
Textiles with self-cleaning and anti-icing capabilities in cold climates are essential for outdoor workers and enthusiasts. Superhydrophobic modification of textile surfaces is effective in imparting these characteristics. Although there are numerous methods available for manufacturing superhydrophobic textiles, careful consideration is warranted for environmental concerns over fluorochemicals, stability of superhydrophobic coatings, and fabric breathability. In this work, we utilized biomass resources such as tung oil and behenic acid, along with zeolitic imidazolate framework (ZIF-8), to modify cotton fabrics, thereby creating an innovative behenic acid/tung oil/ZIF-8 modified cotton (BTZC) fabric with anti-icing and self-cleaning features. This material manifests a unique nanoflower-shaped surface morphology, demonstrating exceptional superhydrophobicity with a static water contact angle (CA) of 162° and a sliding angle (SA) of 2°. Moreover, BTZC excels in its thermal stability, breathability, and resistance to icing. Equally impressive is its robust stability, as evidenced through rigorous testing under continuous washing and abrasion, sustained high and low temperatures, extreme pH environments, and immersion in various chemical solvents. BTZC presents as a fluorine-free, durable, economically viable alternative for outdoor textile applications, marking substantial progress in the utilization of biomass and metal-organic framework materials in the textile industry and promising implications for value enhancement.
摘要：
在寒冷气候中具有自我清洁和防冰能力的纺织品对于户外工作者和爱好者来说是必不可少的。纺织品表面的超疏水改性在赋予这些特性方面是有效的。虽然有许多方法可用于制造超疏水纺织品，对于含氟化合物的环境问题，需要仔细考虑，超疏水涂层的稳定性，和织物的透气性。在这项工作中,我们利用了生物质资源，如桐油和二十二烷酸，与沸石咪唑酯骨架(ZIF-8)一起，修改棉织物，从而创造了一种创新的二十二烷酸/桐油/ZIF-8改性棉（BTZC）织物，具有防冰和自清洁功能。这种材料表现出独特的纳米低体形状的表面形态，表现出优异的超疏水性，静态水接触角（CA）为162°，滑动角（SA）为2°。此外，BTZC的热稳定性很好,透气性,和抗结冰。同样令人印象深刻的是它强大的稳定性，通过在连续洗涤和磨损下的严格测试证明，持续的高温和低温，极端pH环境，和浸泡在各种化学溶剂。BTZC表示为无氟，耐用,户外纺织品应用的经济可行替代方案，标志着纺织工业中生物质和金属有机骨架材料的利用取得了实质性进展，并对价值提升产生了有希望的影响。
