Innovative Measurement Techniques and Applications of Aqueous Graphene-Based Conductive Paint

Conductive paint, as a novel method to advance electronic product manufacturing technology in the coming decades, is gradually becoming a crucial element in inkjet printing and sensing and monitoring fields. In this study, we successfully prepared water-based conductive paint with nanographene as the base material through a simple solution mixing and dispersion-solidification process. Moreover, the prepared conductive paint can quickly solidify in the air and maintain its conductivity stability through multiple uses and measurements. We employed an improved Van der Pauw method in this research to measure the resistivity and sheet resistance of the conductive paint coated on a cellulose paper substrate, evaluating its conductivity. The results revealed an outstandingly low resistivity of (0.001404±0.000015) Ω·m. This remarkable conductivity highlights its enormous potential applications in areas such as sensors, flexible circuits, and wearable devices.
