|Abstract:||A mathematical model for stimuli-sensitive hydrogels in a water-alcohol solution is presented and analyzed, in which a new polymer-solvent interaction parameter is proposed to capture the deformation of the hydrogel due to changes in the external alcohol content and temperature. The nature of this parameter is determined in the limit of pure dilatation for poly(N-isopropylacrylamide) hydrogels immersed in tempered water-methanol and -ethanol solutions. Overall, good agreement between the resulting model predictions and experiments is achieved; the transition temperatures and "re-entrant phenomenon" are also captured reasonably well. The herein derived expression for the polymer-solvent interaction parameter can be introduced into more generic transient models that also account for fluxes of the relevant field variables. © 2011 Imperial College Press.|
