一种耐磨抗紫外抗静电超疏水织物及其制备方法
相关申请的交叉引用。
本申请要求于2021年5月25日提交中国专利局，申请号为202110573633.1，发明名称为“一种耐磨抗紫外抗静电超疏水织物及其制备方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及亲水织物领域，特别是涉及一种耐磨抗紫外抗静电超疏水织物及其制备方法。
 背景技术
近年来，荷叶表面特殊的防水性能引起了人们的广泛关注。研究发现，荷叶表面多层次的微纳米结构和疏水的蜡质材料赋予了其表面优异的超疏水性能。这种特殊的润湿性使其在防水、油水分离、防结冰、抗腐蚀、自清洁、微流体运输等领域有着巨大的应用前景，特别是在户外防水织物制品的应用。然而，在实际应用中，超疏水材料表面的低表面能材料与基材附着力差，易脱落，多层次粗糙结构还易受到各种外力冲击、磨擦或液体腐蚀的破坏，此时不仅疏水性能大幅度下降，还可能对水产生粘附。此外，将超疏水材料置于户外时还会遭受紫外等的照射导致材料的降解。同时，超疏水材料表面的疏水性可能会导致表面干燥而产生静电积累，吸附灰层破坏表面的超疏水性，因此，超疏水材料的耐磨性和耐久性是制约其产业化应用的关键因素。
 技术问题
现有技术公开了一种超疏水抗紫外织物的方法，主要在超疏水中引入有机抗紫外化合物提高其抗紫外性能，但是有机抗紫外化合物的稳定性有待提高。Ren等将氧化锌（ZnO）与有机硅树脂（PDMS）复合，在织物表面构造了超疏水涂层。研究发现，该涂层可以抵抗强酸、强碱与饱和盐溶液，此外，由于ZnO/PDMS与织物具有较好的结合力，通过手指刮擦和砂纸磨擦测试后仍然保持良好的超疏水性能，ZnO/PDMS涂层还可以有效屏蔽紫外光，使该材料具有良好的抗紫外老化性能（Guina Ren, Yuanming Song, Xiangming Li, et al. A simple way to an ultra-robust superhydrophobic fabric with mechanical stability, UV durability, and UV shielding property [J]. Journal of Colloid and Interface Science, 2018, 522: 57-62）。Zhu等通过对铜表面刻蚀后，再经过PDMS和二氧化钛对表面进行改性，制备了水接触角为155.5°，滚动角为6.8°的超疏水涂层。该涂层具有光催化性能，能有效降解表面的有机污染物，同时涂层具有优异的抗紫外性能，在经过30h的紫外线照射后仍然保持优异的疏水性（Hai Zhu, Lizhen Wu, Xiang Meng, et al. An anti-UV superhydrophobic material with photocatalysis, self-cleaning, self-healing and oil/water separation functions [J]. Nanoscale, 2020,12(21): 11455-11459）。利用二氧化钛和氧化锌的特性可以一定程度上起到较好的抗紫外效果，但是紫外照射会引发二氧化钛和氧化锌的光催化效应，可能会导致基体树脂PDMS的降解。利用基材表面的多层次结构维持超疏水所需的粗糙结构，获得的材料具有较好的稳定性，但是需要对无机粒子进行疏水化改性，同时无机粒子在摩擦过程中需要维持多层次的微纳米结构以截取更多的空气层来保持表面的疏水性，因此耐磨性有待提高。
