Design and Preparation of a New and Novel Nanocomposite with CNTs and Its Sensor Applications

Abstract

Inorganic–organic nanocomposite poly(o-toluidine) Ce(III)tungstate@CNT was prepared by sol–gel intercalation insertion method, later on it was mixed with CNTs that leads to the formation of CNT intercalated inorganic–organic hybrid nanocomposite. The polymerization of monomer was achieved by ammonium persulphate (APS) chemical oxidation, inside the inorganic matrices that leads insertion of polymer. Characterization of POTCe(III)T@CNT nanocomposite by various physicochemical studies as FT-IR, X-ray, UV–vis spectrophotometry, TEM, SEM/EDX, TGA and four probe conductivity measuring technique was done. On the basis of physicochemical properties as cation-exchange capacity as well as electrical conductivity, the advanced nanocomposite was utilized for the sensor application for environmental remediation. It was used for the preparation of POTCe(III)T@CNT ion selective membrane electrode. Keywords: Nanocomposite, Sensor, Poly-o-toluidine, CNTs, Novel, Tungstate
