Electrical Stimulated Polyvinyl Alcohol-Borax-Graphene Hydrogel for Drug Releasing and Delivery

Polyvinyl Alcohol hydrogel has promising applications in numerous biomedical, biomaterial, and tissue engineering. However, it has poor conductive properties, restraining its development within huge fields such as bio-signals acquisition systems, thermal stability, and drug delivery. Adding Graphene as a nanofiller will produce PVA/Borax/Graphene nanocomposite hydrogel, which is an excellent procedure to significantly improve the conductive properties of PVA. The toxicity will not affect the nanocomposite while very well-dispersed graphene will significantly improve the thermal and conductivity stability of the nanocomposite. In this study, we investigated the performance of a newly prepared conductive hydrogel gel using the freezing/thawing method
