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

Abstract

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 .
