Abstract

The swelling and shrinking dynamics of the gels with a wide variety of aspect ratios is experimentally investigated. As the aspect ratio becomes sufficiently larger or smaller than unity, the swelling kinetics asymptotically approaches that of infinitely long cylinders or infinitely large disks, respectively. The characteristic times of the infinitely long cylinders and infinitely large disks are compared to the predictions of the classical Li-Tanaka model and its modified models.
