电化学驱动无氟水溶胶原位沉积棉织物的超疏水机制及其性能

摘要/Abstract

摘要：

采用电化学驱动水溶胶在织物表面定向原位沉积一层均匀、致密薄膜，赋予棉织物无氟超疏水性能。以表面活性剂为乳化剂制备SiO2水溶胶，并以辛基三乙氧基硅烷为疏水改性剂。研究了电化学沉积电压、沉积时间及表面活性剂质量浓度对织物疏水性能的影响，并分析了织物的疏水耐久性。电化学沉积棉织物与水的接触角可达157.7°，达到超疏水效果。经皂洗后织物接触角仍可达151.1°，具有一定的疏水耐久性。电化学沉积后棉织物力学性能及白度变化不大，而透气性略有降低，但不影响其服用性能。

Abstract:

To endow superhydrophobic property on cotton fabric at the fluoride-free condition, a homogeneous and dense film was directly in-situ deposited on cotton fabric by electrochemical deposition technology with SiO2 hydrosol. SiO2 hydrosol was prepared with emulsifier sodium dodecylbenzene sulfonate and hydrophobic modifier triethoxyoctylsilane. The contact angle of the deposited cotton reached 157.7°, and the fabric was superhydrophobic. Through soap washing, the contact angle of the deposited cotton fabric was 151.1°, and the hydrophobic property was still good. The whiteness and mechanical property were changed slightly, while the breathability was weakly decreased, which didn’t affect the wearing performance.

Key words: electrochemistry, hydrosol, in-situ deposition, superhydrophobic, cotton fabric
