Multifunctional hydrogels with self-healing, stretchable, electro-active and tough properties have attracted a lot of attention in various fields, including soft robotics, wearable electronics, smart sensors, drug delivery, and tissue engineering. In addition, graphene oxide (GO) is an oxidative form of graphene with layered structure and many oxygenated defects can be used for various fields. GO/PAA nanocomposite hydrogel with Fe3+ ions provides self-healing ability by dual cross-linking effects through Fe3+ enabled strong, dynamic and reversible ionic bonding. In this study, we prepared GO-based multifunctional hydrogel using iron chloride and acrylic acid. In addition, their mechanical and electrical characteristics are investigated under an electrical stimulation. |
