para-Phenylenediamines (pPDAs) were mixed with aniline to synthesize a low molecular weight, nanowired polyaniline via emulsion polymerization, which demonstrated smaller intrinsic viscosity. Fourier transform infrared-spectra illustrated the presence of phenazines in the polymers in the presence of pPDA. Free carrier-tails in UV-Vis-NIR spectra are still present but their numbers decreased with pPDAs. Scanning electronic microscopy and transmission electronic microscopy (TEM) images showed the neat PANINTs shrank significantly and became randomly distributed after dedoping but the diameters of the PANINT-pPDAs decreased slightly. TEM micrographs demonstrated the hollow morphology for the neat PANINTs but that of PANINT-pPDA was shorter, solid nanowires. X-ray diffractions patterns illustrated a layered structure for neat PANINTs which own a long c-axis, not found for PANINT-pPDAs. (C) 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
