Hydrogels: Hydrogel Paint (Adv. Mater. 39/2019)

In article number 1903062, Zhigang Suo and co-workers report a principle to develop green hydrogel paint based on decoupling of the synthesis and cure processes. As a result, after being manufactured in a factory, the paint product can be used to create hydrogel coatings by anyone. Such a principle re-opens numerous ways to use hydrogel coatings in education, engineering, and medicine.
