TH158808A - Graphene Paste Electrodes for Electrochemical Measurement and Graphene Paste Electrodes Manufacturing Method - Google Patents

Abstract

OCR 09WP 04/03/2025 This invention demonstrates the fabrication of graphene electrodes for electrochemical measurements using screen printing technology, comprising the steps of grinding pure graphene powder to a micron level and then drying it at 100 °C for 2 hours. The graphene powder is weighed to obtain an appropriate ratio of pure graphene powder to carbon paste, and grinds it to a homogeneous consistency with a viscosity of 3.1-5.8 Pa.s. (Pascals seconds) to be used as a screen printing ink for the fabrication of graphene electrodes. The fabrication process uses PVC sheets as a substrate with a screen mesh. The optimal temperature for drying electrodes screen-printed on PVC sheets is 60 °C for 10 minutes, a condition that provides low resistance and a short time to reduce the fabrication time. Examination of the electrode properties using the cyclic voltammetry electrochemical technique revealed that electrodes made from 10 percent graphene paste provide the best electrical conductivity of the graphene paste. It provides 1.5 times higher electrochemical signal than carbon paste electrodes.
