Abstract
A versatile ionic crosslink lithography (ICL) approach is reported to achieve geometry transitions of strong polyvinyl alcohol/sodium alginate (PVA/SA) hydrogels in a controllable and programmable manner. Specifically, localized PVA/SA and PVA/SA/Fe 3+ hydrogel domains of significantly different swellabilities (i.e., in‐plane gradient) are created by patterning and selective ionic crosslinking of one single type of PVA/SA hydrogel. A simple...
