Abstract

Semi-interpenetrating polymer network (semi-IPN) hydrogels composed of chitosan and polyaniline (PANi) were prepared and the effects of various pHs and temperatures, and the electrical responsiveness, were studied. The swelling ratio of semi-IPNs depended on pH and temperature. The stimulus responses of semi-IPNs in electric fields were also investigated. When swollen, semi-IPNs were placed between a pair of electrodes, and exhibited bending behavior upon the application of an electric field. The electroresponsive behavior of the semi-IPN was also affected by the electrolyte concentration of the external solution. The semi-IPN also showed various degrees of increase of bending behavior depending on the electrical stimulus.
