Stimulus-responsive polymers can be caused structural deformation controlled by physical or chemical stimuli such as light, sound, pH, magnetic field, ionic strength, etc. In particular, electro-active hydrogels showed reversible expanding, shrinking and bending behaviors influenced by electric field. It can be used as artificial muscle, smart sensor, biorobotics, aerospace field and so on because of its biocompatibility, high water content and good flexibility. In this research, we fabricated three-dimensional structure network polyanion hydrogel including ionic group for soft actuators. The gel fraction, swelling properties, mechanical strength were exercised for intrinsic ability of hydrogels. In addition, the various shapes of the hydrogel samples were investigated in electric field. |
