ELECTRODIC POLYMER MATERIALS BASED IN ANILINE: INFLUENCE OF Ni2+, Co2+, AND Cu2+ IONS ON ITS FORMATION
Behaviour of aniline when voltametrically electropolymerized in the presence of Ni2+, Co2+, and Cu2+ cations has been studies 0.1 mol ·L-1 aniline in the presence of 0.01 mol·L-1 copper(II), nickel(II), and cobalt(II) ions and of three inorganic acids: HCl, HNO3, and H2SO4, was used. Aniline shows t...

| Sumario: | Behaviour of aniline when voltametrically electropolymerized in the presence of Ni2+, Co2+, and Cu2+ cations has been studies 0.1 mol ·L-1 aniline in the presence of 0.01 mol·L-1 copper(II), nickel(II), and cobalt(II) ions and of three inorganic acids: HCl, HNO3, and H2SO4, was used. Aniline shows that polymerizes in all strong acids and metal ions selected, the reversibility and clarity of the redox processes in the presence of metal ions, indicate that the most accurate conditions for electrosynthesizing polyaniline (Pani) was CuCl2 in 1.0 M HCl; Ni(NO3)2 in 1.0 M HNO3 and in HNO3 1.0 M Co(NO3)2. In all cases, similar voltamograms were obtained and polymer growing changes according to the metal ion used. For Co(II), is more favorable in the following order: H2SO4 > HCl > HNO3. For Ni(II) is H2SO4 > HCl @ HNO3, and for Cu(II) is H2SO4 > HCl @ HNO3. The aim of this work is to study the effects of metal ions on aniline and their electropolymerization in acid media |
