Abstract

Polyvinyl alcohol (PVA) with the desired bio-properties and relatively low cost has attracted special interest to make hydrogels, especially with the wound dressing application. On the one hand, irradiation is an appropriate method to prepare hydrogels based on PVA. In this method, the irradiation conditions, especially the irradiation dose, influence significantly the physical properties and therefore affect the performance of the hydrogel. The main objective of this research was to investigate the effect of electron beam irradiation dose on the physical and thermal (crystallinity) properties of PVA hydrogels. The hydrogels were prepared by irradiation of the aqueous solution of PVA (7 wt.%) at different doses. The gel content, equilibrium swelling degree and dehydration behavior of the hydrogels were evaluated. The chemical structure changes of the PVA due to irradiation and thermal behavior of the dried PVA gels were probed respectively by FTIR and DCS experiments. In the wake of increasing the dose, the gel content of the hydrogel increased marginally, while its swelling decreased significantly. There was no obvious effect on the hydrogel dehydration by changing in the dose. The FTIR results showed that besides the crosslinking, the PVA chains degradation was also augmented with the dose. According to the DSC results, increasing the dose caused reduction of the crystallization and melt temperatures of the PVA and increment of its crystallinity.
