A Transparent and Anti-Fog Polyethylene Film

The present disclosure generally relates to a stretchable anti-fogging tape (SAT) that can be applied to diverse transparent materials with varied curvatures for persistent fogging prevention. The SAT comprises three synergistically-combined transparent layers: i) a stretchable middle layer with high elastic recovery to keep transparent materials tightly bound; ii) an anti-fogging top layer to impart hydrophilicity to transparent materials; and iii) an adhesive bottom layer to form robust yet reversible adhesion between transparent materials and SATs. The SAT can be configured to have water condensate form a predominantly continuous film thereon in response to a high humidity environment At least two applications are demonstrated, including the SAT-adhered eyeglasses and goggles for clear fog-free vision, and the SAT-adhered condensation cover for efficient solar-powered freshwater production.
