    In order to find a hydrogel that has good properties for use in microvalve actuators experiments have been conducted to find a hydrogel composition that has good swelling behavior and shows a discontinuous volume transition.

    During the experiments a number of N-isopropylacrylamide (NIPA) and acrylamide (Am) hydrogels were synthesized with varying amounts of the comonomer acrylic acid (AA). The swelling behavior of these hydrogels was characterized by measuring the swelling in acetone/water mixtures with varying concentrations acetone.
