Abstract

Dehydrated polyacrylamide gel was investigated by measuring Raman spectrum, thermal and elastic properties with increasing temperature. The elastic stiffness showed remarkable change around the temperature where a thermal anomaly occurred (Tg), demonstrating occurrence of the glass transition at Tg. However, a low frequency Raman peak could be still distinguished even far above Tg, indicating the complex structure of the network and solvent in the dehydrated gel.
