Abstract

The outstanding characteristics of graphene, with its good mechanical and electrical characteristics, have made it one of the best candidates to replace other conductive material when developing conductive ink. Graphene properties and the way to improve it have been researched for a decade. In this study, the development of graphene-based conductive ink and graphene properties was overview in order to understand more about the characteristics of graphene, binders and substrate. Some research was conducted to find a factor that could affect the performance of graphene conductive ink, in order to develop a new idea to improve the production of graphene conductive ink. This study shows that the performance of graphene conductive ink is mostly influenced by the conductive ink structure. While the good surface and structure of the graphene conductive ink depending on the stage of the sample preparation. This is because a lot of errors can occur at that time. For example, the formulation matrix for composition, the temperature for the curing process and patterning and printing method. Such factors may have an effect on the development of conductive ink. Therefore, this study focused more on observing the effect of various curing temperatures in order to produce a good linkage between the binders and the filler and several experiments are also being performed to determine the resistance, voltage and microscopy image of the graphene conductive ink. The study was conduct on three size of sample which is 1 mm, 2 mm and 3 mm and with four difference patterns and was cure under temperature of 90 ℃, 100 ℃ and 110 ℃. The outcome show sheet resistivity was lower at 3 mm width and at temperature of 110 ℃. Thus the finding from this study are, sheet resistivity was decrease by increasing the width and the curing temperature for graphene based conductive ink
