Electroactive polymer gels composed of poly(diallyldimethylammonium chloride), poly(acrylic acid) and poly(vinyl alcohol) were prepared and their swelling properties characterized. The swelling behavior of the polymer gels was studied by immersion of the gels into deionized water at room temperature. The state of the water in the polymer gels was characterized using differential scanning calorimetry and the microstructure of the swollen gel in each sample was investigated using scanning electron microscopy. The samples' response to being stimulated in an applied electric field was also investigated. Copyright © 2005 Society of Chemical Industry
