Investigation of attenuation x-ray by preparing nanocomposite based on CdS and polythiophene

Nanocomposites of conducting polythiophene and cadmium sulfide (CdS) has been synthesized via in situ polymerization. Cadmium sulfide was prepared from the cadmium sulfate hydrate (CdSO4·8/3H2O) and elemental S. Aqueous solutions of NaOH, Na2SO3 and EDTA were used as the solvents. During the syntheses, we used a direct immersion ultrasound. Anhydrous FeCl3 as an initiator and dodecylbenzene sulfonic acid as a doped agent were used for nanocomposite preparation. The products were characterized by TEM, X-ray powder diffraction (XRD) and four-wire-technique respectively. Afterward X-ray interaction parameters such as linear attenuation coefficient, attenuation percentage, half value thikness and mean free path were examined, in similar situation. Also, in order to determine the effect of radiation beam on destroying the polymer chains, we measured the conductivity of samples before and after photon interaction and result proven that conductivity of remain unabated
