Synthesis and some physical properties of conducting polymer poly (o- toluidine)‎ doped with dodecylbenzene sulphonic acid (pot-dbsa)‎

الملخص EN

Poly(o-toluidine) (POT) doped with dodecylbenzene sulphonic (DBSA) was prepared by chemical methods and then dried in an oven at 50 oC for a period of 48 hrs.

Powder of the doped polymer was dissolved in suitable solution in the concentration of 10 mg.ml-1.

These films were prepared by spin coating method on glass substrate .

Thin films were then placed on a hotplate with temperature of 90°C for a period of 15 min for drying.

The Fourier Transform Infrared (FTIR) spectra and ultraviolet visibility (UV- VIS.

absorption) spectra, were used to characterize the structures of (POT-DBSA).

The optical absorbance and transmitted are used to calculated the optical parameter and the indicated that the transition was direct transition ,with direct energy gap about 2.5 eV .

Current- voltage characteristic of AL/POT-DBSA/AL is also investigated .and show ohmic behaviour .
