“…1 Additions of hydroquinone were also successfully used. 7 Recent publications describe that the gas bubble formation during the electrophoretic deposition from aqueous suspensions can be avoided when a pulsed-DC field of suitable pulse width 8 or an asymmetric AC field 9 is applied instead of the commonly used continuous DC field.…”

“…Also, Sakurada et al. [13] report that adding hydroquinone into the solution increases the deposition weight thanks to its reaction with the O 2 gases released. Besra et al [14,15] can also be cited as having succeeded in reducing bubble formation using a pulsed electric field.…”

International audienceThe present study investigates the pulsed electrophoretic deposition of boehmite particles, previously dispersed in an aqueous solution, into the pores of a model anodic film, prepared using phosphoric acid electrolyte, on an aluminium alloy 1050 (AA1050) substrate. Particles were successfully inserted into the pores, despite some limitations resulting both from the barrier layer, which transpired to be semi-conducting, and from water electrolysis. To address this issue, a pulsed electric field, set to above a threshold value, allowed a current to be sent through the cell, this being accompanied by a reduction of water electrolysis; insertion of particles thus became possible. Scanning Electron Microscope (FEG-SEM) observations, X-Ray Diffraction (XRD) spectroscopy and Electrochemical Impedance Spectroscopy (EIS) studies gave some clues as to the reality of particle impregnation into the pores. Furthermore, an improvement in the porous anodic film filling was achieved using hydrothermal post-treatmen

“…Chemical additives, such as hydroquinone, have been also used to control oxygen generation at the anode electrode. However, the application of such additives is only under limited conditions such as alkaline pHs [18,19]. Besra et al [20,21] suggested the use of pulsed direct current (PDC) for suppressing and controlling the extent of bubble generation during EPD.…”

Fabrication of multi-walled carbon nanotube thin films via electrophoretic deposition process: effect of water magnetization on deposition efficiency

et al. 2015

In this study, the effect of water magnetization was investigated on the performance of electrophoretic deposition (EPD) of multi-walled carbon nanotubes (MWCNTs). Magnetization of water was carried out via two different methods including static and dynamic magnetization processes. It has been found that magnetization of water, as the EPD medium, could enhance several characteristics of MWCNT thin films (MWCNT-TFs). Application of magnetized water as solvent in EPD process resulted in higher electrical conductivity of EPD suspension; consequently, required deposition time was reduced and the electrolysis of water, which is known as one of the main disadvantages of water-based EPDs, was controlled to some extent. Surface morphology of MWCNT-TFs was studied via scanning electron microscopy, and notable enhancement was detected in uniformity and density of MWCNT-TF network. Significant improvement was achieved in electrical conductivity (up to 54 % increase in current) of MWCNT-TF by measuring the current versus voltage characteristics of MWCNT-TFs.
