Chemically and physically diverse hydrogels have become standard materials for drug delivery, contact lenses, corneal implants, and scaffolds for the regeneration of new skin, tendons and cartilage, and the encapsulation of cells. In recent years, there has been a growing interest in hydrogel systems prepared by gamma-ray irradiation. The gamma-ray irradiation method has advantages, such as relatively simple manipulation without need of any extra agents for polymerization and crosslinking. In this study, we synthesized temperature-responsive hydrogel system with bilayer structure for soft actuator applications. The bilayer-type hydrogels were prepared using gamma-ray irradiation and their physicochemical properties were investigated to evaluate the feasibility of using the hydrogels in soft actuators. Gel fraction, thermally responsive swelling-deswelling behavior and bending properties were also determined. |
