Silica-based porous glass films, known for their high transparency and superhydrophilicity, are promising anti-fogging materials. Shirasu, a volcanic ash from southern Kyushu, has been successfully used to fabricate such films. However, their hydrophilicity deteriorates over time due to the loss of surface hydroxyl groups from contamination and abrasion.While porous structuring enhances water absorption, a trade-off between film thickness and absorption efficiency poses challenges for further improvement. Spin-coating, a cost-effective method for thin-film formation, has been studied on micro structured surfaces but remains largely unexplored for nanoscale spinodal structures. This study investigates the feasibility of using spin-coating to apply a hydrophilic solvent-based organic coating, aiming to achieve a stable and durable hydrophilic layer.
