We demonstrate in this study a wrinkle-free, superhydrophilic cotton fabric (contact angle ∼0°) by uniformly attaching specially engineered nanoparticles to plasma-pretreated cotton fabric. Because of their highly charged nature, the nanoparticles are firmly anchored on the fabric via electrostatic interactions, as confirmed by microscopy and chemical analyses. The durability of wetting behavior and wrinkle-free property of the nanoparticle-coated fabrics were evaluated via aging, laundering, and abrasion tests. The strongly attached coatings are stable enough to maintain their superhydrophilic nature even after 60 days of aging at room temperature, 50 laundering cycles, and 25 000 abrasion cycles. Moreover, the nanoparticle-coated superhydrophilic fabrics exhibit great wrinkle-recovery property, tensile strength, and abrasion resistance performance up to 25 000 abrasion cycles.
本研究通过将特制的纳米粒子均匀地附着在经等离子体预处理的棉织物上，展示了一种无皱、超亲水的棉织物（接触角约为 0°）。由于其高度带电的性质，纳米粒子通过静电相互作用牢固地固定在织物上，这一点通过显微镜和化学分析得到了证实。通过老化、洗涤和磨损测试评估了纳米粒子涂层织物的润湿行为和无皱性能的耐久性。附着牢固的涂层非常稳定，即使在室温下老化 60 天、洗涤 50 次和磨损 25000 次后，仍能保持超亲水的特性。此外，纳米粒子涂层的超亲水织物在磨损 25000 次循环后仍表现出良好的褶皱恢复性能、拉伸强度和耐磨性。
