The electrophoretic deposition process has gained wide attention as a novel
technique for the preparation of thin films, one dimensional nanostructures,
monolayers and other nanostructures, due to its low cost, formation of
homogeneous coatings and high versatility of application of the formed
materials. In this work, nickel hydroxide particles were prepared from NiCl2 and
NH4OH solutions, by heating 90 s in a conventional microwave oven. The
resulting dispersions were mixed with aluminum acetate solutions at different
concentrations in order to produce nickel-aluminum layered double hydroxide.
After 24 h of reaction at room temperature, the mixture were filtered and
washed with distilled water and ethanol, and the powder products were dried
at room temperature. Finally, the powders were dispersed in isopropanol and
electrophoretically deposited on aluminum plates at 12 V during 15 min. The
resulting coatings were characterized by X-ray diffraction, diffuse reflectance
spectroscopy, FTIR measurements and scanning electron microscopy. The
characterization results show that a composite of Ni(OH)2 / Ni-Al layered double
hydroxide was obtained with typical laminar morphology, and the characteristic
reflections of Ni(OH)2 phase and Ni-Al layered double hydroxide.
