| Hazard Information | Back Directory | [Chemical Properties]
Polyaniline is dissolved in methyl pyrrolidone, and the resulting solution is cast onto substrates such as glass, plastic, and metal. The solvent is slowly evaporated at 60-80°C to produce a large-area support film with excellent mechanical and electrical properties. The tensile strength, Young's modulus, and elongation at break are 88, 1560, and 10%, respectively. After doping with hydrochloric acid, the strength decreases slightly, but the toughness increases, with an elongation at break reaching 58%. | [Uses]
PANI can be used in the formation of a conjugating system that finds potential applications in semiconductors. It can be used in the fabrication of a variety of devices which include fuel cells, light emitting diodes supercapacitors, chemical sensors(10) and rechargeable batteries.(11) | [General Description]
Inherently conducting polymer based additive. Stable up to at least 300°C in air. Polyaniline is environmentally stable and with tunable conductivity. 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. |
