A Smart Design Strategy for Super-Elastic Hydrogel with Long-Term Moisture, Extreme Temperature Resistance, and Non-Flammability.

ABSTRACT: Elastic hydrogel is a promising material category for designing biological muscles, repairable building materials, flexible electronic devices, and vulcanized rubber substitutes, which is required to have a long life, good self-healing performance and extreme temperature tolerance. Herein, a super-elastic mineral hydrogel is developed with long-lasting moisture, based on dynamic physical crosslinking between hydrated calcium ion clusters and amide groups of polyacrylamide (PAM). The complex hydrogel exhibits a super stretchability of 13 600% at room temperature, and can maintain the super flexibility in a wide temperature range of -40-50 °C or for a long period of 28 days. Particularly, the soft material cannot be ignited under an open flame at 400-500 °C, because of coupling dual flame re
