Effect on Electrical Conductivity of Graphene Nanoparticle Filled Epoxy Conductive Ink

Abstract

The development of a variety of printing methods and compatible conductive inks supports the emerging high demand for production of printed electronic devices. Conductive ink is used to create conductive paths as interconnecting tracks for the printed electronic devices. Extensive research has been performed to produce lightweight conductive ink using composite materials with high electrical conductivity, environmental stability, and good engineering properties. The method of integrating various conductive materials using thermoplastic viscous paste was introduced in order to enhance the ability of conductive ink to conduct electricity. Carbon nanomaterials offer many opportunities in conductive ink applications, especially for printed and flexible electronics. Therefore, this study aims to produce highly functional conductive ink using graphene nanoparticles with epoxy as a binder by investigating the electrical behaviors of newly formulated graphene nanoparticle conductive inks of different patterns and width.
