Generación de estados superficiales durante la formación electroforética catódica de películas de TiO2 sobre ito

Abstract: Recebido em 29/3/10; aceito em 29/9/10; publicado na web em 26/1/11 SURFACE STATES GENERATION DURING CATHODIC ELECTROPHORETIC DEPOSITION OF TiO 2 /ITO FILMS. In the present work TiO 2 films were formed over Indium Tin Oxide (ITO) employing cathodic electrophoretic deposition (Cathodic-EPD) and Dr. Blade Technique. The films were characterized by electrochemical techniques in order to compare their electronic properties; as well as, their photoelectrochemical behavior. The electrochemical performance showed by … Show more

“…The suspensions employed for the tests constituted 100 mg of TiO 2 in 1 L of a solvent composed by 5.0% v/v 2-propanol and distilled water. 18,19 For the measurements of electrophoretic mobility (m) versus pH, 0.1 M NaOH and HCl solutions were used to change the pH of the suspensions. The evaluation of the dispersant effect in m of TiO 2 particles was carried out for a concentration range of between 0.0 and 1.0% w/w.…”

“…Baker 99.97%) and distilled water, with 500 mg of TiO 2 , in an ultrasonic bath for 10 min. 18,19,24 The quantity of Anatase and Rutile added was 500 mg, but the Anatase fraction in the powders was changed (1.0, 0.8, 0.7, 0.5, 0.0). As the TiO 2 acquire a negative surface charge in the suspension, the stainless steel foils, employed as substrates for the films, were used as anodes while another stainless steel foil was used as a cathode.…”
