Abstract

Self-cleaning outdoor garment fabrics are desired. However, traditional fiber cloths made from cellulose show a poor antifouling property owing to surface hydrophilicity. In this work, fiber@poly(vinyl silsesquioxane) (POSS) fabric with self-cleaning trait and superhydrophobicity was fabricated via surface ultraviolet (UV) curing (UV-induced click reaction). Its surface micromorphology and elemental distribution were studied. Compared with pristine fiber cloth, POSS-modified fiber cloth can exhibit the superhydrophobic, nonstick, and antifouling traits. Superhydrophobicity of the modified cloth is ascribed to synergy between high surface roughness (cage-like POSS; crosslinked (3-mercaptopropyl)trimethoxysilane; woven fibers) and low-surface energy (Si/-CH₂-). Self-cleaning property of modified cloth results from superhydrophobicity. After water/surface contact for 60 min, the static water contact angle of modified cloth surface can reach 158.7 ± 1.6°. Superhydrophobic durability of modified cloth reaches 120 h under acid/base/UV irradiation. After 100 abrasion cycles or 1 laundering cycle, the superhydrophobicity is maintained. The novelty of this work is a rapid UV-curing fabrication of self-cleaning POSS-modified fiber cloth. This work might open up a way for preparing advanced self-cleaning garment fabrics.

利用uv固化诱导高表面粗糙度制备自洁超疏水fiber@POSS服装面料

需要具有自清洁功能的户外服装面料。然而，由纤维素制成的传统纤维布由于其表面亲水性而表现出较差的防污性能。本文采用表面紫外线固化(UV-induced click reaction)的方法制备了具有自清洁特性和超疏水性的fiber@poly(乙烯基硅氧烷)织物。对其表面微观形貌和元素分布进行了研究。与原始纤维布相比，poss改性纤维布具有超疏水、不粘、防污等特点。改性布的超疏水性归因于高表面粗糙度(笼状POSS;交联(3-mercaptopropyl) trimethoxysilane;低表面能(Si/- ch2 -)。改性布的自洁性能源于其超疏水性。水/面接触60min后，改性布表面的静水接触角可达158.7±1.6°。改性布在酸/碱/紫外线照射下的超疏水耐久性可达120 h。经过100次磨损或1次洗涤后，超疏水性得以保持。这项工作的新颖之处在于一种快速的紫外光固化制备自清洁poss改性纤维布。这项工作可能为制备高级自洁服装面料开辟一条道路。
