Abstract
The conductive thin film was made based on bio-based epoxy and graphite compounded with its cross-linker (Methylene Diphenyl Diisocyanate, MDI) and further blended with disparate percentages of pretreated graphite. The preparation of this solution started by drop casting as thin films, where the thickness of thin film was set approximately ~0.1 mm. Optical microscope, Fourier transform infra-red spectroscopy (FTIR) and Ultraviolet-visible (UV-vis) spectrophotometer has been operated to diagnose Graphite/ biopolymer composites in order to have better and accurate results of this work. The current-voltage (I-V) characteristics of the composite thin film samples were measured at room temperature. This study shows the electrical conductivity was discovered and calculated by achieving conductivity of 103 S/m as a prove that this thin film has the ability to conduct electricity.
