A hydrogel is a polymer that can contain a large amount of water and is a promising material that can be applied to various fields. However, it has weak mechanical properties because of its inhomogeneous structure and lack of an energy dissipation mechanism. Accordingly, a high-strength hydrogel having a structure such as a nanocomposite or a double network has recently been developed. However, its use is still limited due to low processability. Therefore, it is necessary to develop a hydrogel that can be processed as well as have high mechanical properties. In this study, to solve the above problem, we prepared a hydrogel that forms physical bonds through dynamic ionic interactions rather than conventional chemical bonds. In the developed hydrogel, different reversible phase-change properties were observed depending on the manufacturing conditions, and the mechanical properties of the material were evaluated through the Universal Testing Machine (UTM).
