Stretchable Anti‐Fogging Tapes for Diverse Transparent Materials

Surface wetting prevents surface fogging on transparent materials by facilitating filmwise condensation with specific chemistry, but suffers from material and geometry selectivity. Extreme environments associated high humidity mechanical loading further limit their anti-fogging persistence. Here, a stretchable tape (SAT) that can be applied to diverse varied curvatures for persistent prevention is reported. The SAT consists of three synergistically combined layers: i) tough layer large elastic recovery, ii) an endurant insensitive ambient humidity, iii) robustly reversibly adhesive layer. maintains total transmittance (>90%) low diffuse (<5%) in high-humidity environments, under various modes deformations, over prolonged lifetime (193 days tested so far). Two applications are demonstrated, including the SAT-adhered eyeglasses goggles clear fog-free vision, cover efficient solar-powered freshwater production.
