Modification Effect of Carbon Nanotubes by LiCl (CNTs/LiCl) on the Electrical Conductivity Character

C arbon nanotubes have been modified by mass percentage variation of LiCl using reflux method. Mass percentage variation used in this study was 0, 1, 5, and 15%. The purpose of this study was to determine the effect of LiCl dope on the electrical conductivity of carbon nanotubes. This research was used reflux method by heating at 80 ° C for 24 h. The products produced were in the form of CNTs / LiCl dry powder s . The characterization results of FT-IR spectroscopy showed that there was a Li-O bond group in the addition of 1, 5, and 15% LiCl while X RD characterization results did not show any diffraction of lithium chloride. The results of this study showed an increase in electrical conductivity at 15% addition of LiCl which was of 2.69 x 10 -3 S/m. Electrical conductivity in the addition of 1% and 5% LiCl decreased (1.17 x 10 -6 S/m and 2.64 x 10 -6 S/m) from CNTs/LiCl 0% (3.68 x 10 -6 S/m) due to the influence of the PVA high resistivity used as an adhesive in the pellets fabrication.
