Abstract
Screen printing electrodes are now a days mostly used in many applications such as battery electrodes, biomedical, biosensors, boilermakers and other. In the present work, graphene oxide (GO)-based screen printing electrodes (SPEs) were successfully prepared on glass substrates using the screen printing technique and systematically characterized to evaluate their structural and morphological properties. Commercially available AR-grade GO nanopowder was utilized to prepare a thixotropic paste using ethyl cellulose (EC) and butyl carbitol acetate (BCA) in a 70:30 organic-to-inorganic ratio. The surface morphology studied by Scanning Electron Microscopy (SEM) revealed porous, wrinkled, and sheet-like structures of GO, providing a high surface area and interconnected pathways. Energy Dispersive X-ray (EDX) spectroscopy confirmed the presence of carbon (68.60 wt%, 74.43 at. %) and oxygen (31.40 wt. %, 25.57 at. %), indicating successful oxidation and functionalization of graphene. X-ray Diffraction (XRD) analysis showed a characteristic (001) diffraction peak at 2θ ≈ 11.1° (JCPDS No. 75-1621) with an interlayer spacing of 0.79 nm, while the crystallite size estimated using Scherrer’s formula was found to be 12.55 nm. These results confirm the successful preparation of GO-based SPEs with desirable nanoscale features, making them promising candidates for electrochemical, sensing, and energy-related applications.
