Effects of filler loading, carbon black structure and types of filler on electrical conductivity of rubber

In this study, rubber samples were prepared based on different loading, different carbon black structure and different types of filler. The mixing and sampling method was done using two roll mill machine. The electronic conductivity of the rubber sample was tested using Impedance Spectroscopy. From the result, it showed that an increase of carbon loading leads to an increase of electrical conductivity of rubber. But, until 20g loading, maximum tunneling of electrons occurs and further increase of carbon, resulted in decreasing of the conductivity.20g loading was then used to compare between different types of carbon structure and from the result, it proved that a carbon with higher structure has a higher electrical conductivity while by comparing types of filler, carbon showed the higher conductivity.
