The Electrical Properties of Poly(o- toluidine) Doped with DBSA Blend with Polyethylene Oxide PEO as Nano Conducting Polyblend

Poly (o-toluidine) (POT ) doped with Dodecyl benzene Sulfonic Acid DBSA synthesis by chemical polymerization method using ammonium persulphate as oxidizing gent. Nano Conducting polyblends POT-DBSA/POE films were prepared by mixed different ratio (0 – 10%, 150%, 25%, 35% ,45%and 50%) of polyethylene oxide polyethylene oxide (PEO) with conducting polymer (POT-DBSA) and prepared by spin coating method . Morphology and diameters of the nanofibers were studied by Atomic Force Microscope (AFM). The diameter of nanfiber was about 85.49 nm (at 15 wt% PEO concentration) and increased with increasing concentration to 105 nm (at 50 wt% PEO concentration). . The electrical properties of conducting polyblends POT-DBSA/POE were measured by two probes method. I-V characteristic of these films at different weigh ratio of POE were investigated .They showed ohmic behavior at all applied voltages . The electrical conductivity increases as POE increase from7.2 x10- 7 S/cm at 0% to 4.48 x10- 5 S/cm at 50% ..The activation energy at temperature were found at rang (293-353)K are also investigated .
