摘　　要：超疏水织物具有突出的拒水性和自清洁性,在生产和生活中具有广泛的应用。文中以溶胶凝胶法制备的纳米TiO_(2)溶胶和十二烷基三甲氧基硅烷为原料,以具有纵向分裂结构的米字形截面涤纶纤维织物为基材,通过低温氧等离子体预处理、浸轧处理和高温固化处理,在织物纤维上构筑了具有多级粗糙度结构的超疏水表面,制备了具有高疏水耐久性和疏水自修复性的功能纺织品。结果表明:改性纳米TiO_(2)在纤维表面形成了致密且交联的疏水网络,织物表面的静态水接触角达到159.1°,整理后的织物具有优良的耐久性,且具有很好的疏水自修复性。Super-hydrophobic fabric has outstanding waterproof and self-cleaning properties, which is widely used in daily life and manufacture. In this paper, Nano-TiO2 sol and dodecyltrimethoxysilane(DTMS) were used as the raw materials, and the polyester fiber fabric with longitudinal split double-cross shaped structure was used as the base material. The super-hydrophobic surface with multistage roughness was constructed on the fiber to prepare durable and self-healing Nano-TiO_(2)coated super-hydrophobic fabrics through plasma pretreatment, dip-padding treatment and high temperature curing process. The results show that the modified Nano-TiO_(2)formed a dense and cross-linked hydrophobic network on the surface of the fiber, and the static water contact angle on the surface of the fabric reached 159°.The treated fabric has excellent durability and hydrophobic self-healing property.
