Abstract
An interpenetrating polymer network (IPN) hydrogels composed of polyacrylic acid-co-poly(vinyl sulfonic acid)/polyaniline(PAA-co-PVSA/PANi) was prepared and exhibited electrical sensitive behavior according to applied electric stimuli. It is studied that hydrogels caused reversible volume change due to the switched electric stimuli. The positive electrode showed contractile behavior and the negative electrode showed expansion. The behavior of the hydrogels induced by electric voltage and moving counterions in solution show rapidly increasing variation (contraction and expansion) with time. As of increasing voltage have been increased the variation velocity of the volume change of the hydrogels. The rate of change of the volume of the hydrogel is related to the applied voltage. The hydrogels showed the behavior with applied electric stimuli, which is very important behavior for application as an actuator.
