摘　　要：Superhydrophobic glass has inspiring development prospects in endoscopes,solar panels and other engineering and medical fields.However,the surface topography required to achieve superhydrophobicity will inevitably affect the surface transparency and limit the application of glass materials.To resolve the contradiction between the surface transparency and the robust superhydrophobicity,an efficient and low-cost laser-chemical surface functionalization process was utilized to fabricate superhydrophobic glass surface.The results show that the air can be effectively trapped in surface micro/nanostructure induced by laser texturing,thus reducing the solid-liquid contact area and interfacial tension.The deposition of hydrophobic carbon-containing groups on the surface can be accelerated by chemical treatment,and the surface energy is significantly reduced.The glass surface exhibits marvelous robust superhydrophobicity with a contact angle of 155.8°and a roll-off angle of 7.2°under the combination of hierarchical micro/nanostructure and low surface energy.Moreover,the surface transparency of the prepared superhydrophobic glass was only 5.42%lower than that of the untreated surface.This superhydrophobic glass with high transparency still maintains excellent superhydrophobicity after durability and stability tests.The facile fabrication of superhydrophobic glass with high transparency and robustness provides a strong reference for further expanding the application value of glass materials.超疏水玻璃在内窥镜、太阳能电池板等工程和医学领域具有广阔的发展前景。然而,实现超疏水性所需的表面形貌将不可避免地影响玻璃的表面透明度,限制玻璃材料的应用。为解决表面透明度与超疏水性之间的矛盾,本文采用了一种高效、低成本的激光化学表面功能化工艺制备了超疏水玻璃表面。结果表明,激光织构可以有效地将空气捕获在表面微纳结构中,从而减小固液接触面积和界面张力。化学处理可加速表面含碳疏水基团的沉积,显著降低表面能。在分层微纳结构和低表面能的共同作用下,玻璃表面表现出卓越的超疏水性,接触角为155.8°,滚动角为7.2°。制备的超疏水玻璃的表面透明度仅比未处理表面的透明度低5.42%。这种具有高透明度的超疏水玻璃经过耐久性和稳定性试验后,仍保持着优异的超疏水性能。这种高透明度、高鲁棒性的超疏水玻璃的制备工艺可为进一步拓展玻璃材料的应用价值提供了参考。
