摘要: Abstract Composites consisting of polyaniline (PANI) and gold nanoparticles (AuNPs) with an average size 17 30 nm were synthesized by interfacial method performed in immiscible water/toluene biphasic system. The effect embedded AuNPs on the morphology, structure physicochemical properties Au/PANI nanocomposites was investigated using scanning transmission electron microscopies, UV–vis, FTIR, Raman ICP-AES spectroscopies, X-ray diffraction, elemental analysis conductivity measurements. Microscopy studies indicated nanofibrous morphology for pure PANI nanocomposites, while FTIR spectroscopies confirmed emeraldine salt form chains presence phenazine units. Also, spectroscopy measurements revealed inherent structural inhomogeneity at macromolecular level that exist its as well nanocomposites. In addition, increase electrical observed discussed.
