Where this comes from

Abstract

The self-healing and self-recovery of the hydrogel materials can be promoted under sunlight without the assistance of electrical equipment by adding a light-to-heat conversion substance during the synthetic process, which will greatly extend the service life of the hydrogels even for the elastomer materials in the off-grid areas.
