A mixture of corn starch and glycerol plasticizer then blended with liquid natural rubber (LNR) and 10 phr carboxymethyl cellulose (CMC) has been successfully carried out to produce a conductive polymer composite (CPC) with a conductivity of 8.0×105 at a frequency of 100 Hz. 6 wt.% of graphite is used as a modifier agent in determining the electrical conductivity properties. Material characteristics and electrical properties of the obtained materials were studied. The mechanism of the effect of several graphites as conductive fillers on the functional properties of CPC was discussed. It was found, that the amount of conductive filler significantly affects the level of conductivity properties. The use of 6 wt.% of graphite is more optimal in comparison with samples without adding graphite. The form of a porous nanocube owned by CGG-6 supports the transition process from insulating properties in CG to being conductive due to the formation of conduction pathways in the composite. In particular, the conduction path formed causes the percolation threshold to exceed its critical value and enhances the electrical conductivity. Thus, CPC with 6 wt.% of graphite filler has the highest electrical conductivity in comparison with unfilled one. This approach is promising to impart conductivity properties for corn starch-based insulation polymer. [ABSTRACT FROM AUTHOR] |
