Structural and Electrical Properties of Graphite in Polyaniline/Graphite (PANI/G) Composites

Abstract:

Polyaniline and graphite composites at different graphite loading were synthesized via solution method by using N-Methyl pyrrolidone (NMP) as a solvent. The structural and electrical properties of the composites were analyzed by using XRD, FT-IR and four-point probe method. The increment in the graphite content improved the conductivity of polyaniline (PANI) from 0.017 to 0.050 S/cm. The improvement in conductivity were also being observed through peak shifted in XRD pattern and FT-IR spectra.
