Abstract

Photothermal superhydrophobic coatings suffer performance degradation in low-temperature, high-humidity environments due to vapor-condensation-induced mechanical interlocking within micro/nanostructures. Inspired by the interconnected porous network of dictyophora, we engineered a multifunctional biomimetic coating (PSPA) by incorporating polydopamine (PDA) into a low-surface-energy polymer network and precisely regulating microphase separation to construct a dictyophora-mimetic interconnected microporous architecture. This bioinspired design enables efficient vapor transport (29.8% transmission rate of ordinary cement boards), effectively suppressing vapor condensation and ice-substrate mechanical…
