摘要： 【目的】利用结构协同效应设计有机 -无机杂化涂层体系，进一步研究改性 SiO2添加量对“高附着力-大粗糙度 -低表面能”复合涂层疏水性和耐磨性的影响。【方法】以全氟辛基三氯硅烷（ FOTS）、正硅酸四乙酯（TEOS）、 3-缩水甘油基氧基丙基三甲氧基硅烷（KH-560）为原料，构建有机 -无机杂化涂层体系，并添加 KH-560改性的 SiO₂颗粒以提升纳米颗粒在涂层中的分散性，采用喷涂法制备耐磨超疏水涂层。通过红外光谱仪、扫描电镜、接触角与耐磨性测试对涂层结构与性能进行分析。【结果】当改性 SiO₂添加量为 100 mg时，复合涂层水接触角达 151. 0°，达到超疏水标准；经 40次摩擦周期后保持 117. 7°，耐磨性与疏水性优异。【结论】通过 FOTS和 TEOS共水解可以降低涂层表面能，构建微纳粗糙结构，提高疏水性；加入偶联剂 KH-560及其改性的纳米 SiO₂能够改善有机相与无机相的界面结合，进一步提高表面粗糙度，增加涂层与基体附着力，提升疏水性和耐磨性。

Abstract: ［Objective］ This study utilizes structural synergistic effect to design an organic-inorganic hybrid coating system，investigating the effects of modified SiO₂ dosage on the hydrophobicity and wear resistance of the composite coating featuring high adhesion，high roughness，and low surface energy.［Methods］Using perfluorooctyltrichlorosilane（FOTS）， tetraethyl orthosilicate（TEOS）and 3-glycidyl oxypropyltrimethoxysilane（KH-560）as raw materials，an integrated organic-inorganic hybridcoating system was constructed through structural synergistic design. Modified SiO₂ particles with KH-560 were added to enhance the dispersion of nanoparticles in the coating. The wear-resistant superhydrophobic coating was prepared via spray deposition. Performance characterization was conducted using infrared spectroscopy，scanning electron microscopy，contact angle measurements and wear resistance tests.［Results］ When 100 mg of modified SiO₂ was added，the composite coating achieved a water contact angle of 151. 0°，meeting superhydrophobic standards. After 40 friction cycles， the contact angle remained at 117. 7°，demonstrating excellent wear resistance and hydrophobic performance.［Conclusion］The co-hydrolysis of FOTS and TEOS can reduce the surface energy of the coating，build rough micro-nano structures，and enhance hydrophobicity. The addition of couplingagent KH-560 and KH-560-modified nano-SiO₂ can improve the interfacial bonding between organicand inorganic phases. It further increases the surface roughness，and enhances the adhesion between coating and substrate，as well as hydrophobicity and wear resistance.
