Summary:A new series of dodecyl benzenesulfonic acid (DBSA) and silver nanoparticles doped poly (anilineco-4-fluoroaniline) nanocomposites were synthesized by chemical oxidative in-situ polymerization method. The characterization of these copolymer nanocomposites were carried out by using FTIR, UV-visible spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and a standard four probe conductivity method. The synthesized copolymer shows good solubility in common organic solvents such as DMF, THF and NMP. UV-Vis absorption spectrum shows 320 and 623 nm which corresponds to the π-π* and polaronic band. In FT-IR spectroscopy a band around 2924 cm-1 corresponds to C-H vibration indicating good agreement with the characteristics bands of DBSA. XRD reveals the crystalline nature of copolymer. The scanning electron microscopic study shows the surface of the nanocomposites has the spherical granular structure of agglomerated morphology with average size of 100 nm. The increase in conductivity is also due to the chemical interaction of nano-scaled DBSA coated Ag nanoparticles in the poly (aniline-co-4-fluoroaniline) matrix that leads to the faster charge transfer.
