This study presents the development of a transparent superhydrophobic coating on glass substrates using hydrophobic fumed silica (HF-SiO₂) and waterborne polyurethane (WPU) as raw materials, combined with a simple spray-coating technique. The resulting coating exhibited a water contact angle (WCA) of 158.7 ± 1.5° and a sliding angle (SA) of 6.2 ± 1.8°, demonstrating excellent superhydrophobic properties. Characterization techniques such as SEM, EDS, LSCM, FTIR, and XPS revealed the presence of micron-scale protrusions and a nano-scale porous network composite structure on the surface. The coating also showed high transparency, with the light transmittance of the coated glass substrate reaching 96.1% of that of the bare glass substrate. Additionally, the coating exhibited self-cleaning ability and extremely low interfacial adhesion. These properties make the transparent superhydrophobic HF-SiO₂@WPU coating suitable for various applications, including underwater observation windows, building glass facades, automotive glass, and goggles. The study highlights the potential of this coating in maintaining high light transmittance while achieving superhydrophobic properties, addressing a significant challenge in the field of superhydrophobic materials.This study presents the development of a transparent superhydrophobic coating on glass substrates using hydrophobic fumed silica (HF-SiO₂) and waterborne polyurethane (WPU) as raw materials, combined with a simple spray-coating technique.
