Electrophoretic‐deposited Superhydrophobic Coatings

Abstract

Electrophoretic deposition (EPD) is an excellent surface coating approach widely investigated for applications ranging from solar cells, batteries, electrochemical capacitors, solid oxide fuel cells, sensors, molecular sieves, corrosion‐resistant coatings, and biomedical materials. On the other hand, superhydrophobic (SHPC) surfaces have enticed substantial recent research interest owing to their superb surface properties. Here, we provide a comprehensive review of electrophoretic‐deposited SHPC coatings. Concise descriptions of EPD and superhydrophobicity are provided first, followed by a brief mentioning of works reported on electrophoretic‐deposited SHPC coatings by one‐step or two‐step processing (§2.1). The next section (§2.2) delivers a comprehensive description of these reports based on the micro/nanoparticles used. Works reported in specific applications such as anti‐corrosion, biomedical, and oil‐separation are described in §2.3. Future scopes of research also presented.

Changes in the Wettability of Microporous Copper Layers Prepared by Different Modes of Electrodeposition

“…S9a-c, respectively. The switching of superhydrophobicity to superhydrophilicity was reported before, and it is very likely on surfaces with interconnected pores as the liquid in the material will fill the pores ahead of the advancing drop [30][31][32][33][34]. An increase in the pore size triggers the capillary wicking, leading to instantaneous spreading of the water droplet.…”

Improving thermal conductivities of textile materials by nanohybrid approaches

“…Electrophoretic deposition (EPD) is an easy method to produce functional coatings based on the use of the deposition of charged particles/molecules in a solvent on oppositely charged particles through electric field-assisted migration. It is a cost-effective and scalable method with high versatility but it suffers from the need of a stable suspension and sufficient particle charge and undesirable electrochemical reactions ( Saji, 2021 ).…”

Durable Superhydrophobic Coating for Efficient Microplastic Removal

“…This combined morphology and their level of structure produced a hierarchical structure that is a key point in the superhydrophobic properties of the coating. In fact, the method used to obtain the superhydrophobic coating involved two different processes: electrodeposition (EDP), also known as electroplating, and electrophoresis (EPD) [32]. EDP is based on the Faradaic process where ionic species from the ethanol solution consisting of ZnCl 2 deposits under certain voltages.…”
