Abstract

Graphite is made up of layers of carbon atoms, which slide easily. This means that graphite is very soft, and can be used as a lubricating oil to make mechanical equipment work more smoothly. Graphite is gray. Due to the delocalization of electrons between its surfaces, graphite can function as an electrical conductor. A conductor plate is a plate that can conduct electrical energy which has a low resistivity value and a large enough conductivity value. In this study, a coating was carried out on the conductor plate using graphite oxide by printing using the compression molding method. The aim of this research was to make a layer of graphite oxide on a conductor polymer plate by compression molding, to determine the effect of graphite oxide coating on the mechanical properties of the microstructure and electrical conductivity, to observe the microstructure of the conductor plate after coating, then to determine the resistance of the conductor plate by performing a bending test. The tests carried out include electrical conductivity tests, microstructural observations and calculation of the bending strength of each sample. There were 3 specimens in the sample with the composition of specimen 1, namely 75% Graphite, 20% Epoxy Resin, 5% Graphite Oxide. Specimen 2 composition is 75% Graphite, 15% Epoxy Resin, 10% Graphite Oxide. And specimen 3 composition is 75% Graphite, 10% Epoxy Resin, 15% Graphite Oxide. The results showed that the highest electrical conductivity value was in specimen 3 with a value of 100 S/cm, and the highest bending test value was in specimen 3, which was 90.0 N/mm^2.
