| Summary: | This paper focused on using a hybrid conductive filler to enhance the conductive polymer composite (CPCs) properties,
especially the electrical conductivity and tensile strength. CPCs can be used for various applications in electronic devices;
however, CPCs have low electrical conductivity. Therefore, a hybrid filler was chosen because it has the potential to produce
higher electrical conductivity compared with a single filler. In this study, the CPCs were prepared by compounding using a
mechanical mixer followed by a casting process. Graphite (10 wt%) with a particle size of 5µm (G5) as the secondary filler
resulted in an electrical conductivity of 0.029 S/cm and tensile strength of 3.6 MPa. These results succesfully improved the
electrical conductivity of the CPCs more than 100% compare with a single filler CPCs at the same amount of 50 wt% conductive
filler.
