An Industry Friendly Approach for the Preparation of Magnetic and Electro-Conductive Polyaniline Composite Particles

Abstract

Recently nano-sized conducting polymers have gained ample attention because of their unique properties and promising potentiality in nanomaterials and nanodevices. Among the conducting polymers, polyaniline (PANi) is the most studied conducting polymers because of its low monomer cost, ease of preparation, high conductivity in doped form, excellent environmental stability, controllable physical and electrochemical properties by oxidation and protonation. In this investigation magnetic PANi composite particles were prepared following a novel approach by using citric acid for the first time as dopant, surfactant and solubilizing agent. As synthesized citric acid doped

Fabrication and properties of polyaniline/ramie composite fabric based on in situ polymerization

“…4 Among them, polyaniline has drawn enormous attention from researchers and industry people because of its low cost, simple fabrication, high conductivity and better chemical stability compared to other conductive polymers. 5,6 Polyaniline has been widely used in solar cells, 7 chemical sensors, 8 electromechanical devices, 9 electromagnetic shielding devices, 10 filtration 11 and antistatic materials 12 due to its electrochemical activity and electrochromic properties. 13 Polyaniline (in its emeraldine base with the same number of oxidation units and reduction units) becomes electrically conductive after doping with protonic acid.…”
