Descripción

General description

Form of polyaniline complexed (doped) with proprietary organic sulfonic acid. Polyaniline is environmentally stable and with tunable conductivity.3 Synthesis of polyaniline (PANI) emeraldine salt by chemical oxidation has been reported. It was observed that sulfonated dyes chemically interact with the charged backbone of PANI. PANI selectively adsorbs the sulfonated dye. Spectral, diffraction and conductivity measurements of the polymer has been reported in the same study. 1

Inherently conductive polymer.
Stable at 100 °C and at 200 °C for short periods. Dispersed particles tend to reaggregrate in molded articles forming conductive pathways. Acidic salt of an organic acid, incompatible with most bases.
Form of polyaniline complexed (doped) with proprietary organic sulfonic acid

Application

A variety of nanomaterials like silver nanoparticles (AgNPs), graphene oxide(GO), aluminum oxide(α-Al₂O₃), carbon fiber and graphite can be potentially used in conjunction with PANI for the development of translational medicine, supercapacitors, triboelectric nanogenerators, and other energy storage applications.

Additive in polymer blends and liquid dispersions for electromagnetic shielding, charge dissipation, electrodes, batteries and sensors. Polyaniline may be used for linear actuator applications. 1
