    Abstract: 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.

    Abstract: An expandable hydrogel structure formed of a housing with a superabsorbent material disposed and sealed therein, particularly wherein the housing is fabricated of a hydrogel membrane with a plurality of macropores providing fluid communication between the superabsorbent material and an exterior of the housing. Exposure of the superabsorbent material to an expansion trigger expands the housing from an initial size to an expanded size that is at least about 50 times to at least about 100 times the initial size. One or more therapeutic agents can further be disposed within the housing to provide controlled release of the therapeutic agents from the expanded housing for extended periods.
