“…As the voltage increases beyond 50 V, the deposit yield increase rate starts to decrease logarithmically with increasing voltage, demonstrating a divergence from a linear Hamaker's law relationship. A recent simulation study by Salazar et al [22] demonstrated that the reason for the nonlinear yield growth is caused by the depletion of suspended particles in the vicinity of the depositing electrode when deposition occurs at high applied voltage and long deposition time. As the electric field pushes the particles toward the depositing electrode, a region devoid of particles develops due to mass conservation.…”

Electrophoretic Deposition (EPD) has become a method for fabricating and enhancing electrodes for electrochemical energy storage (EES) devices. This article explores the impact of dominant EPD parameters on the deposit yield and coating thickness of graphite produced from an organic-based graphite particle suspension. The deposit yield follows a linear Hamaker's law at voltages below 50 V, with a deposition time of up to 5 minutes and solid loading between 2.5 to 12.5 mg/mL. The study also demonstrates the successful deposition of negatively charged and non-colloidal sized graphite particles, which are previously dispersed in n-butylamine-acetone without the use of charging or binding additives. This later forms a coating with a relatively strong binding strength of graphite particles on the steel anode. EPD of graphite suspension with a concentration of 5 mg/mL at a deposition voltage of 10 V and 5 minutes deposition time is capable of producing a graphite coating thickness of 70 mm. This research demonstrates the high-yield capability of EPD of organic-based graphite particles on metal anode and provides valuable insight for future investigations into application of binderless graphite suspension particles for electrode materials in energy storage systems.

“…In recent years, (EPD) is taken in to consideration in both industrial and academic sectors; not because of the versatility of this method with different materials specially compounds, but also because of its simple and cheap equipment that needed for deposition [12,13]. EPD method has been used successfully for gas diffusion electrodes [14] and sensors [12], silica thin films [15], layered ceramics [16], multi-layer composites [17], hydroxyapatite Coatings [18], layers contained carbon nanotubes [19], functionally graded ceramics [20], and piezoelectric materials [21]. So, the mentioned coating method is not a new method.…”

The electrophoretic deposition coating method has recently received attention as a new method for thermal barrier coating due to its advantages such as the simplicity of the method, controllability of the process, and the need for simple equipment. In this study 8 wt % yttria- stabilized zirconia was deposited on Inconel 738 substrate at room temperature by electrophoretic deposition. Before deposition, the substrates were treated by sand blasting treatment (by silica sands with different sizes) and roughness in the range of Ra=1 and Ra=3 was achieved on the substrate surfaces. The coated samples were sintered at 1100 °C temperature under controlled atmosphere (Ar atmosphere). X-Ray diffraction, scanning electron microscopy and thermal shock resistance technics were used to investigating of structural and phase properties and adhesiveness between coatings and substrates. Results from thermal shock resistance test show that by increasing roughness number, the thermal shock resistance ability first increased and then decreased. In addition, according to SEM images, increasing of roughness number, causes decrease the microcracks that creating in the coating surface. The best result was observed for coatings deposed on substrate with Ra=2.

“…Additional advantages include but are not limited to the short time of deposition, the few constraints on the shape of the substrate (carrier) and thus the ability to coat substrates with complex shapes, and the fact that, in contrast to other advanced deposition techniques, the EPD process can be easily modified for a particular application; it also allows the creation of composite layers [17,18]. For example, deposition can be performed on flat or cylindrical surfaces, or any other surface, and this requires only minor changes in the design of electrodes and their positioning [19]. Among other materials, it is possible to deposit graphene oxide and a graphene oxide/titanium oxide mixture on an aluminum substrate using the electrophoretic deposition process [20,21].…”

Polymer-Based Electrophoretic Deposition of Nonwovens for Medical Applications: The Effect of Carrier Structure, Solution, and Process Parameters

Hyaluronate and alginate are non-toxic and biocompatible polymers, which can be used for surface modification and functionalization of many kinds of materials. Electrophoretic deposition (EPD) has several advantages, including its versatility, simplicity, and ability to coat substrates with complex shapes, and is used for the creation of antimicrobial or hydrophobic coatings on metallic biomaterials, among other applications. However, its utilization for applying biopolymer layers on textiles is very limited due to the more complex structure and spatial characteristics of fibrous materials. The aim of this research was to analyze the effects of selected EPD process parameters and the structural characteristics of fibrous carriers on the kinetics of the process and the microscopic characteristics of the deposited layers. The influence of solution characteristics, process parameters, and carrier structures obtained using two different techniques (melt blown and spun-bonded) were analyzed. The morphology and structure of the created deposits were analyzed using scanning electron microscopy and computed tomography, and molecular structure analysis was performed with Fourier Transform Infrared spectroscopy. The surface mass and thickness of fibrous poly (lactic acid)-based carriers were analyzed in accordance with the respective standards. This study serves as a basis for discussion and further development of this method with regard to fibrous materials for medical applications.
