Abstract
A series of new poly(aniline co-o-anthranilic acid) / copper, or cobalt composites were synthesized via chemical oxidation copolymerization with potassium dichromate as the oxidant in the presence of Cu, or Co by both in situ and ex situ methods. Aniline, o-anthranilic acid monomers and metal ratios were (1:1:0.5 and 1:1:1). The morphological, structural, and thermal properties were characterized with X-ray diffraction, Fourier transform infrared, thermogravimetric analysis, differential thermal analysis, and ultraviolet-visible spectroscopy. Greater 50% degradation temperature and char yield were observed in PANAA EB-Co vs. PANAA EB-Cu composite. The copper doped PANAA has been used as precursors to produce CuO in the nanoscale by annealing in air directly. The stages of decompositions and the calcination temperature of the precursors have been determined from the thermal analyses (TGA). The obtained CuO nanoparticles have been characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). TEM showed CuO nanoparticles with average particle size 25-44 nm.
