Allgemeine Beschreibung

Form of polyaniline complexed (doped) with proprietary organic sulfonic acid.
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

Anwendung

Additive in polymer blends and liquid dispersions for electromagnetic shielding, charge dissipation, electrodes, batteries and sensors.
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.
