Long-lasting and stable anti-fog coating combined with active and passive strategy.

ABSTRACT: There is an urgent need to design long-term effective anti-fog coatings to ensure the stabilization of uniform water films on hydrophilic surfaces, considering the impacts of interfacial strength, cyclic drying, and contaminants. Here, we propose an anti-fog strategy that leverages manipulating free volume and hydrogen bonding of hydrophilic networks through the twisted non-coplanar structures, synergized with photothermal effects, to enhance anti-fog efficiency. The introduction twisted non-coplanar structures of 1(2H)-phthalazinone not only significantly enhances the coating's interfacial stability but also increases the molecular free volume, thereby substantially improving its moisture absorption capacity and extending the anti-fogging duration. The developed coating simultaneously ach
