Time-Temperature Mechanical Response of a PVA Dual Cross-Link Self-Healing Hydrogel

Uniaxial tension tests and small strain rheology tests were performed on poly (vinyl alcohol) (PVA) dual cross-link hydrogel specimens at different temperatures under different loading rates. The effects of loading rate and temperature were studied in both experiments. The rheology results were analyzed using classic time-temperature superposition. It can be concluded that for the rheology data classic time-temperature superposition works for this PVA hydrogel under the tested temperature range.
