Formation of Cupric Oxide Films on Quartz Substrates by Annealing the Copper Films

In the present work, cupric oxide (CuO) films were obtained through thermal annealing of the copper (Cu) films deposited on quartz substrates by DC magnetron sputtering method. The annealing was performed in air atmosphere for different times ranging from 60-240 min at temperature of 400 ºC. The influence of annealing times on structural and morphological properties of the films was investi...

The critical effect of pH on the formation of organic coatings on mild steel by the aqueous electropolymerization of 2-vinylpyridine

Coatings of poly(2-vinylpyridine) have been formed on mild steel substrates in aqueous medium by electrochemical polymerization of the 2-vinylpyridine monomer. The pH of the solution has been found to be critical for this electropolymerization coating process. At low pH (below 3.5), even with an efficient initiation reaction, the propagation process was impeded and no substantial polymer film w...

Electropolymerization of Metalloporphyrin Films for Catalytic Reduction of Dioxygen

Two types of porphyrin free base, meso-tetra(4-vinylphenyl)porphyrin and meso-tetra(4-stilbenyl)porphyrin, were synthesized and characterized. Metallation was achieved by insertion of MnCl24H2O. Oxidative electropolymerization of the manganese porphyrin monomers by cyclic scans would anchor the resulting materials on glassy carbon electrodes. It was found that both poly (manganese tetra(4-vinyl...
