Synthesis and characterization of conductive nanoblends based on poly(aniline-co-3-aminobenzoic acid) in the presence of poly(styrene-alt-maleic acid)



In this article, we describe electrically conductive nanoblends containing poly(aniline-co-3- aminobenzoic acid) (PANABA), poly(styrene-alt-maleic acid) (PSMAC), and polystyrene. PANABA copolymers on a nanoscale were prepared under ultrasonic irradiation by the oxidative copolymerization of aniline and 3-aminobenzoic acid at different molar ratios. PSMAC was also prepared in our laboratory. The obtained conductive nanoblends formed films with good homogeneity and flexibility. The conductivity of the obtained nanoblends was measured with a four-probe method. The maximum electrical conductivity obtained was 0.60 S/cm. The characterization of the obtained copolymers and nanoblends was carried out by Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, and X-ray diffraction. Scanning electron microscopic images were taken from the obtained nanoblends. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
