Hydro-locking in hydrogel for extreme temperature tolerance

Science, Год журнала: 2025, Номер 387(6737), С. 967 - 973

Опубликована: Фев. 27, 2025

Hydrogels consist of cross-linked polymers that are highly swollen with water. Water evaporation or freezing during temperature changes may lead to stiff and brittle hydrogels. We introduce a strategy called “hydro-locking,” which involves immobilizing the water molecules within polymer network hydrogel. This is accomplished by establishing robust connections between using sulfuric acid. A sacrificial introduced shield prime from collapsing. Under hydro-locking mode, an alginate-polyacrylamide double-network hydrogel remains soft stretchable range spans –115° 143°C. The works hydrogels solutions enable preservation observation materials even living organisms at extreme temperatures.
