Electrophoretic deposition (EPD) is a colloidal process where the suspended particles are impelled from the suspension medium to the substrate by an electric field. EPD was discovered by Ruess in 1808 and was practically applied to deposit thoria particles on a Pt cathode as an emitter for electron tube in 1933.Abstract: Electrophoretic deposition (EPD) is a colloidal production process developed in the early 20th century. Industrial scale EPD for the production of electronic components and phosphorescent screens and in the electrophoretic deposition applications
This conference follows from the success of the first five International Conferences on Electrophoretic Deposition: Fundamentals and Applications, organized under sponsorship of ECI in August 2002 (Canada) June 2005 (Italy), October 2008 (Japan), October 2011 (Mexico) and October 2014 (Austria).
At early stages of electrophoretic deposition, the absorption is dominated mainly by the TiO 2 film (spectra a and b in Fig. 20). With increasing deposition time, an increase in the absorption was noticed in the visible wavelength range (spectra cj). The mechanisms of electrophoretic deposition (EPD) are discussed and their shortcomings identified. The kinetics of the processes involved are analyzed for constantcurrent and constantvoltage conditions. A method of determining the Hamaker constant of suspended particles is developed by modelingelectrophoretic deposition applications Numerous applications of electrophoretic deposition are described, including production of coatings, freestanding objects, and laminated or graded materials, infiltration of porous materials, and fabrication of woven fiber preforms.
The electrophoretic deposition (EPD) technique is an attractive approach for development of graphene and graphene oxide (GO) films for a variety of applications. However, in order to establish the influence of the EPD parameters on the properties of the deposited films, a deeper investigation of the fundamental GOEPD kinetics is required. electrophoretic deposition applications
