“…The four-point probe method [14] was used for the determination of electrical conductivity of the polyaniline and GA-PANI hybrid by making rectangular pressed pallets (pressure 5 tons/cm 2 ). This method was also followed for the study of IV Characteristics of polyaniline and GA-PANI hybrid both.…”

A novel electrically active, water soluble gum acacia-polyaniline (GA-PANI) hybrid was synthesized using ceric ammonium nitrate as initiator in acidic medium. The representative hybrid material was characterized using UV-visible, FTIR and SEM taking polyaniline as reference. The composition of aniline to gum acacia was tailored to optimize possible cross-linking in side the hybrid. The hybrid material exhibited pH switching electrical conductivity, which was decreased with increasing pH of the material. I-V characteristics and acid-base sensitivity of the hybrid material were extensively investigated in order to find out its electronic behavior during current flow.

“…All the characteristic peaks of PANI appear in the spectrum of the urchin-like microstructures. [26] The peaks at 1 599 and 1 528 cm À1 are ascribed to the C --C stretching vibration of the quinonoid and benzenoid rings, respectively, and the peak at 1 306 cm À1 to the C-N stretching vibration. The peaks at 858 and 3 200 cm À1 are assigned to the out-ofplane vibration in the 1,4-disubstituted aromatic rings and the N-H stretching vibration, respectively.…”

Urchin-like PANI microspheres with an average diameter of 5-10 µm have been successfully prepared. Their surfaces consist of highly oriented nanofibers of ≈30 nm diameter and 1 µm length. The solvent composition plays an important role in the formation process of urchin-like PANI microspheres. The structure of the products has been characterized by FT-IR, UV-vis, and XRD. To investigate the self-assembly of urchin-like PANI microspheres, the effect of polymerization time on the morphology of the products has been studied. The morphological evolution process indicates that the urchin-like microspheres originate from the self-assembly of nanoplates, which then grow into urchin-like microstructures with nanofibers on the surface.

Abstract:The use of organic chemistry reactions to introduce additional functional groups on polyanilines is described. Among the reactions discussed are: electrophilic aromatic substitution, nucleophilic addition to the aromatic rings, nucleophilic substitution on the amine groups and reactions on pendant groups. The use of combinatorial chemistry techniques, by coupling of combinatorially synthesised diazonium salts with polyaniline, to produce a functionalized polyanilines library is also reviewed. The modification of polyaniline introduces or alters different properties of the materials: solubility, self-doping and redox coupled ion exchange. The tailoring of those properties to technical applications is therefore examined.
