Synthesis, characterization and electro active properties of poly (MT-co-4-Fluoro aniline) Ag dispersed polymer nano composites

Abstract

A series of electroactive nanocomposites was prepared by in-situ polymerization method. The silver nanoparticles dispersed in poly (metatoluidine-co-4-fluoroaniline) copolymer. The solubility characteristic of these materials are tested in various polar and polar solvents. The m-toluidine-co-4-fluoroaniline silver doped polymer nanocomposites is more soluble in organic solvents. These polymer nanocomposites possess better soluble nature than that of its homopolymer. From the UV–visible spectra absorption band obtained at 382 nm is attributed to the π-π* transition of the benzenoid moiety. The charge transfer process from benzenoid to quinoid, the band at 659 nm. The shifting of bands from 1596, 1488 cm−1 to 1598, 1495 cm−1 in the m-toluidine-co-4-fluoroaniline silver doped polymer nanocomposites observed in FTIR spectra. X-ray diffraction confirms the non-crystallinity of the m-toluidine-co-4-fluoroaniline silver doped polymer nanocomposites at a band around 25°. The crystalline peaks observed at 2θ around 32, 46, 64 and 73°is due to the lattice planes of face-centered cubic (FCC) (111), (200), (220) and (311) silver nanoparticles in poly (m-toluidine-co-4-fluoroaniline). SEM analysis shows the composites exhibits spherical granular sponge structure. They are microclustured in nature having porosity too. The conductivity value of m-toluidine-co-4-fluoroaniline silver doped polymer nanocomposites is decreased from 1.1 × 10-8 S/cm to 0.2524 × 10-8 S/cm.
