Synthesis and characterization of conducting poly N-ethyl aniline doped with organic acids
ABSTRACT:
A substituted polyaniline, Poly
(N-ethyl aniline) (PNEA), doped with different organic acids like acetic acid,
oxalic acid and propionic acid has been synthesized by chemical polymerization
method, using ammonium persulphate as an oxidizing agent. Characterization has
been carried out by UV-Vis spectroscopy, FTIR spectroscopy, and conductivity
measurements. The polymer, poly (N-ethyl aniline) doped with oxalic acid has
been found to be highly soluble in common organic solvents. FTIR studies have
revealed that oxalic acid doped poly (N-ethyl aniline) shows a broad and
intense band at 3732.38cm-1 and 1000-1087 cm-1, accounting for a higher degree
of doping.
