Abstract: ［Objective］Addressing the issues of photovoltaic glass surfaces being susceptible to environmental abrasion and fogging due to water vapor condensation caused by temperature fluctuations.［Methods］ Hydrophilic silane monomer（F6-TMS） was synthesized via silicon hydrogenation addition reaction，and hydrophilic nanoparticles（F6@SiO₂）were produced by hydrolysisand condensation with ethyl orthosilicate. The hydrophilic acrylic resin emulsion（WPA）was obtained by seed emulsion polymerization using allyloxypolyethyleneglycol and acrylate monomers as raw materials. The nanoparticle hybrid superhydrophilic coating F6@SiO₂-WPA was constructed by composite roasting of the two，and the nanoparticles and the resin were characterized by FT-IR and SEM. The wettability，abrasion resistance，transmittance，and anti-fogging properties of the superhydrophilic coating were tested.［Results］The results showed that when F6@SiO₂ was added at 30%，the water contact angle（WCA）of the constructed superhydrophilic coating was 3. 3°，and after 600 cycles of abrasion，the WCA remained below 10° and the coating was in a superhydrophilic state overall. The light transmittance of the coating was 93. 1%，which was 3. 8% higher than that of blank glass，showing a significant light-transmitting effect. After being placed for 30 days，the anti-fog grade of the coating remained at level 0. The superhydrophilic coating showed excellent anti-fog performance and durability.［Conclusion］ F6@SiO₂-WPA provides new solutions in the field of anti-reflection and anti-fogsuperhydrophilic coatings for photovoltaic glass.

摘要： 【目的】改善光伏玻璃表面易受环境磨损，同时因温差变化导致水蒸气凝结起雾等问题。【方法】通过硅氢化加成反应合成亲水性硅烷单体（ F6-TMS），将其与正硅酸乙酯水解缩聚制得亲水性纳米粒子（F6@SiO₂）。再以烯丙基聚氧乙烯聚氧丙烯醚及丙烯酸酯类单体为原料通过种子乳液聚合法制得亲水性丙烯酸树脂乳液（ WPA）。将二者复合焙烧后构筑得到纳米粒子杂化超亲水涂层（ F6@SiO₂-WPA）。通过 FT-IR、 SEM等对纳米粒子及树脂结构进行表征，并对涂层的润湿性、耐磨性、透过率及防雾性进行测试。【结果】 F6@SiO₂质量分数为 30%时，构筑的超亲水涂层水接触角为 3. 3°，循环摩擦 600次后水接触角仍保持在 10°以下，整体呈超亲水状态；涂层透光率为 93. 1%，相比空白玻璃提升 3. 8%，表现明显增透效果。放置 30 d，涂层的防雾等级仍为 0级，超亲水涂层整体展现出优良的防雾性和持久性。【结论】 F6@SiO₂-WPA为光伏玻璃用增透防雾超亲水涂层领域提供了新的解决思路。
