Fabrication and Characterization of Flexible Electrode based on Paper Pulpand Reduced Graphene Oxide

This study introduces a facile and scalable method for producing cellulose-based flexible electrodes,presenting a novel substrate for biosensors. Composite paper electrodes were fabricated from paperpulp and graphene oxide (GO) using solvent casting at room temperature. The electrical conductivityand surface chemistry of the nanocomposite samples were optimized through the chemical reductionof GO. Electrical measurements demonstrated high electrical conductivity with ideal Ohmicbehavior. Scanning electron microscopy was used to investigate the morphology of thenanocomposite films. Current-voltage diagrams showed conductivities of ۰.۲۴ S cm⁻¹ for ۴ wt% rGO,۰.۳۹ S cm⁻¹ for ۸ wt% rGO, ۰.۵ S cm⁻¹ for ۱۰ wt% rGO, and ۰.۶ S cm⁻¹ for ۱۶ wt% rGO, in sampleswith a thickness of ۸۰ μm. This resulting nanocomposite is proposed as a conductive, low-costbiosensor electrode
