Poly(aniline- co -3-aminophenol): enhanced crystallinity and solubility

An improvement of physiochemical properties such as solubility, crystallinity, and the surface morphology of the copolymer have been achieved via the in-situ copolymerization of the monomers units using ammonium persulfate as an oxidising agent. To study the optical behavior of the as-synthesized copolymers UV–Vis spectroscopic analysis has been performed. Atomic force microscopy has been used to study the roughness profile and surface morphology. For the functional group characterization of the copolymer, FT-IR analysis has been considered. Electrical conductivity has been investigated by the two-probe method. The conductivity of copolymers (PA-co-3-AP)s has been diminished overall. The amount of molar feed in the composition determines the nature of conductivity.
