“…Protonation with SBA was shown to produce the longest structure of polyaniline. Polymerization in the presence of PA was shown to produce a short and thick rod, consistent with the finding found by Abe et al (1989). In general, the polyaniline compounds synthesized with the selected acids were shown to have a rod shape structure.…”

“…A number of attempts to improve the solubility have been reported by the use of substituted aniline [11][12][13] or the post sulphonation of PANI [14] which provided a more soluble PANI with a conductivity of about 0.1 S cm -1.…”

The thermal characteristics of polyaniline (PANI), poly(o-aminobenzoic acid) (POABAC) and poly(o-aminobenzyl alcohol) (POABOL) are determined and compared by thermogravimetry (TG) and differential scanning calorimetry (DSC). The higher thermal stability of POABOL is attributed to heat-induced condensation between the polymer chains. The DSC results suggest both intra-and inter-molecular interaction in the form of hydrogen bonding due to the substituent group in POABAC and POABOL. These interactions, however, occur mainly in the doped from and is greatly reduced when the dopant is expelled from the system at higher temperatures.

“…15 In this work, an oxidized PAn film was used as undoped film, and various protonic acids, e.g., HC1, methane sulphonic acid (MS), polyvinyl sulphonic acid (PVSH), polyisoprene sulphonic acid (PISH), and polyvinyl sulfate (PVS) were used as dopants. The immersing conditions are shown in Table I.…”

We examined the influence of polyaniline (PAn)'s unit sequence and doping with low molecular weight dopants or polymer dopants on permeation property. It was found that CO2 permeability was increased by the formation of a quinonediimine unit in PAn with the oxidation. CO2 sorption amount of PAn was decreased by oxidation. The increase of CO2 permeability with oxidation, therefore, resulted from the increase of diffusivity, which was attributable to morphological variation by the increase of a quinonediimine unit. The permselectivity of PAn films was found to be remarkably improved by doping. In particular, the selectivity value of the PAn film doped with polyvinyl sulphonic acid as a polymer dopant went up to over 2,000. This remarkable increase of selectivity was found to result in the increase of selectivity, depending on diffusivity. It was also found that the permselectivity of the PAn film doped by polymer dopants was surpassed, as compared with that doped by low molecular dopants. © 1995 John Wiley & Sons, Inc.
