Terpolymers as precursors for CuO nanoparticles synthesis

Abstract

This work describes the synthesis of terpolymers of aniline, diphenylamine, and o‐anthranilic acid (PANIDPAA) by 1 : 1 : 1 molar ratio of the respective monomers doped by different concentration of copper ions via in situ chemical terpolymerization. The results are justified by measuring spectral characteristics namely, UV‐vis absorption spectra, FTIR, and TGA. Calcining these PANIDPAA terpolymers doped by copper at temperatures in the range of 700°C led to the formation of CuO nanoparticles in the nanoscale by thermal decomposition in air directly. The stages of decompositions and the calcination temperature of the precursors have been determined from thermal analysis data sheet. The obtained CuO nanoparticles have been characterized by X‐ray diffraction and transmission electron microscope (TEM). TEM showed a particle size less than 40 nm. © 2014 Wiley Periodicals, Inc. J.

Polymerization of aniline derivatives by K2 Cr2 O7 and production of Cr2 O3 nanoparticles

“…It has been concluded that the resulting PANI has high molecular weight and electrical conductivity . Recently, Zoromba and Alhussani synthesized terapolymer of (aniline, o‐anthranilic acid and diphenyl amine) emeralidine base at room temperature by potassium dichromate as an oxidizing agent. Furthermore, the poly(aniline co‐anthranilic acid)/ silica nanocomposite was synthesized by an in‐situ chemical oxidative polymerization in acidic medium (HCl) using potassium dichromate.…”
