Abstract
In the present work, effective atomic numbers (Zeff) of polypyrrole have been determined for total photon interactions at energy range 15.74 - 40.93 keV from the accurately measured total attenuation coefficients, by transmission method employing a good geometry setup for characteristic Ka and Kp X-rays of Zr, Mo, Ag, In, Sb, Ba and Pr. 59.54 keV gamma rays from 241 Am (100 mCi) source were used to excite the secondary targets. Characteristic X-rays of related elements after excited have been sent on polypyrrole using as target or absorber. Possible conclusions are compared with the theoretical ones obtained using the XCOM. The polypyrrole film has been directly formed on an aluminum plate by means of an anodization process. A Pt plate was used as the cathode. Anodization process was carried out under constant current conditions of I = 1mA. The polypyrrole/Al/polypyrrole structure was fabricated by an electrolyte being held at a constant temperature of 55 °C that was composed of 0.40 M pyrrole and 0.1 M tetrabutylammoniume tetrafluoroborate. The electrolyte solution was prepared in a propylene carbonate solvent (Merck). The polypyrrole has been coated on each side of aluminum plate. The area and thickness of the A1 plate are 1 cm2 and 0.012 cm, respectively.
