Abstract

We report the swelling properties of physically cross-linked polyvinyl alcohol (PVA) hydrogels prepared by a cast-drying method. The swelling ratio of PVA cast gel in its swollen state decreased after repeated processes of water exchange with drying. The measurements using a Fourier Transform Infrared Spectroscopy and X-ray diffraction suggested that the hydrogen bonds were additionally formed during the process of water exchange with drying. We concluded that non-cross-linked polymers with low molecular weight eluted into the solvent by water exchange and additional hydrogen bonds were formed during the dehydration, which resulted in the decrement of the water content in the swollen state.
