Multi-functional hydrogels with self-healing, elastic, electro-active and coarse properties are being studied intensively in a variety of fields including soft robotics, wearable electronics, smart sensors, drug delivery system, and tissue engineering. Graphene oxide (GO) is a carbon compound containing various functional groups in a two-dimensional planar structure, and has the advantage of excellent electrical conductivity. In this study, we prepared the GO-incorporated composite polymer hydrogel which provided self-healing ability with double cross-linking effect through strong, dynamic and reversible ionic bonds. The gel fraction, swelling properties, and mechanical properties of hydrogels were determined. In addition, their electro-mechanical response under an electric stimulus was investigated. |
