Preparation of Highly Conductive Polyaniline in Carbamide Aqueous Solution Using SnCl₄ as Initiator

Abstract

In this paper, we demonstrated a novel method for the preparation of highly conductive polyaniline (PANI) compounded with Sn(OH)4. We obtained the PANI directly in the oxidation polymerization system via simultaneous reaction of aniline (using ammonium persulfate, APS as oxidant) and SnCl4 in carbamide aqueous solution. The resulting PANI was compounded with Sn(OH)4 had been characterized by FTIR, UV-Vis spectroscopy, X-ray diffractometry, thermal analysis, scanning electron microscope and conductivity measurements, and the results showed that PANI was in well doped state due to the hydrolysis of APS and the complex between PANI and Sn(OH)4. We are sure this alkali-guided polymerization to obtain conductive PANI will lead to the preparation of a new class of PANI composites.

Design, synthesis and physical properties of poly(styrene-butadiene-styrene)/poly(thiourea-azo-sulfone) blends

“…Polymers and polymer-based materials with electroconductive properties are materials with potential applications in antistatic packaging (Anand et al 1998), energy storage (Gulakhmedova et al 1996), electro-optical devices (Cao et al 1993;Wu and Benatar 1997;Lin et al 2012), etc New materials are being offered in every area and novel products are constantly being introduced. Among these new materials, those made of electro-conductive filler in insulating polymer matrix are being used for electrostatic discharge protection, packaging industries, etc (Virtanen et al 1997).…”
