Superhydrophobic cotton fabrics have been widely explored for their excellent properties, although there are still a few limitations in the practical applications for the reasons of poor environmental performance and short service life. In this study, the hexadecyltrimethoxysilane emulsion was prepared using O₂-plasma and ultrasound for the superhydrophobic functional finishing of raw cotton fabric by immersion method. The prepared cotton fabrics showed a superior hydrophobicity with water contact angles larger than 156.0°, as well as an excellent self-healing ability. This self-healing ability was gained by simple heating treatment, which could restore the superhydrophobicity of the hydrophilic cotton fabric damaged by abrasion or O₂-plasma treatment. The superhydrophobic cotton fabrics demonstrated excellent washing durability, which can withstand 50 times accelerated laundering cycles. Besides this, the superhydrophobic coatings also displayed fair chemical stability in strong acidic and alkaline solutions. The prepared nonfluorinated superhydrophobic cotton fabric with self-healing ability shows a potential for practical functional textile application.

超疏水棉织物因其优异的性能而被广泛探索，但由于环保性能差和使用寿命短等原因，在实际应用中仍存在一些局限性。本研究采用O ₂等离子体和超声波制备十六烷基三甲氧基硅烷乳液，通过浸渍法对原棉织物进行超疏水功能整理。制备的棉织物显示出优异的疏水性，水接触角大于 156.0°，以及优异的自愈能力。这种自愈能力是通过简单的加热处理获得的，可以恢复因磨损或O _{2 而}损坏的亲水棉织物的超疏水性。-等离子处理。超疏水棉织物表现出优异的耐洗性，可承受 50 次加速洗涤循环。除此之外，超疏水涂层在强酸和强碱溶液中也表现出相当的化学稳定性。制备的具有自愈能力的非氟化超疏水棉织物显示出实际功能性纺织品应用的潜力。
