Medical Grade Polyurethane Supported Pseudo Capacitor

Abstract

An all solid state, thin and flexible redox supercapacitor fabricated by forming layer by layer films using biocompatible materials and then assembling them together, thus making entire supercapacitor thin while also retaining its flexibility. Using these films, this study has also tested the super capacitive properties of Polyvinyl alcohol, graphene oxide(PVA-GO), Polyvinyl alcohol, glucose(PVA-glucose) and Ionic liquids. Electrochemical characterization has demonstrated a good electrical double layer capacitive behavior. The use of non toxic and biocompatible materials along with its miniature size and mechanical flexibility can find its use in many devices under wide range of conditions especially in medical implantable devices.
