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.
在寒冷气候下具有自清洁和防冰功能的纺织品对于户外工作者和爱好者来说至关重要。对纺织品表面进行超疏水改性可有效地赋予这些特性。虽然有许多制造超疏水纺织品的方法，但需要仔细考虑含氟化学品对环境的影响、超疏水涂层的稳定性以及织物的透气性。在这项工作中，我们利用生物量资源，如桐油和山嵛酸，以及沸石咪唑酯骨架（ZIF-8），来修饰棉织物，从而创造了一种具有防冰和自清洁功能的创新山嵛酸/桐油/ZIF-8 改性棉（BTZC）织物。这种材料具有独特的纳米花状表面形态，表现出出色的超疏水性，静态水接触角（CA）为 162°，滑动角（SA）为 2°。此外，BTZC 在热稳定性、透气性和抗结冰方面表现出色。同样令人印象深刻的是其强大的稳定性，经过连续洗涤和磨损、高低温持续、极端 pH 环境以及浸入各种化学溶剂的严格测试，均表现出稳定。BTZC 是一种无氟、耐用、经济可行的户外纺织品应用替代品，标志着在纺织工业中利用生物量和金属有机骨架材料方面取得了重大进展，并为提高价值带来了广阔的前景。
