Abstract

Dodecylbenzene sulfonic acid (DBSA) doped nanocomposites of Polypyrrole-silicon carbide (PPy-SiC) were synthesized via insitu chemical oxidation polymerization of Pyrrole act as monomer. Dodecylbenzene sulfonic acid and Iron (III) chloride were used as a dopant and oxidization agent, respectively. The molar ratio of monomer unit to oxidization agent was 1:2.4. These nanocomposites were characterized for their structure, thermal stability, surface morphology and DC electrical conductivity by UV-Visible spectroscopy, FT-IR, XRD, TGA, SEM and four-probe method respectively. The electrical property of chemically prepared Polypyrrole and Polypyrrole/SiC in aqueous solution was found to be strongly depending on doping material, oxidant and solvent. It obeys Ohm’s Law and convincing applies for battery technology and sensor applications.
