Abstract: Poly (2, 5-dimethoxyaniline) and Cadmium sulfide nanocomposite blend have been prepared by low cost, feasible oxidative polymerization method. Poly (2, 5-dimethoxyaniline) has been protonated with Camphor sulfonic acid. nanocomposite blend thin films were obtained by blending with CdS into Poly (2, 5-dimethoxyaniline) for different weight percentage by dip coating. The structural, morphological, optical characterizations of pristine Poly (2, 5-dimethoxyaniline) and nanocomposite blend thin films were analyzed. The XRD pattern shows that the crystallinity of the blend film increases with increasing CdS concentration. FESEM images shows porous blend film. The UV-Vis and Photoluminence spectra analysis shows the extension of conjugation length with decreasing band gap with increasing CdS concentration. The presence of functional groups were studied from FTIR spectra. The CSA protonated Poly (2, 5-dimethoxyaniline) – Cadmium sulfide blend films have been investigated as ammonia gas.
