“…The EPD provides such advantages as uniform coating thickness, complex substrate coatings and rapid deposition rate [13] and it can be used for a wide range of materials [14][15][16][17][18][19][20][21][22]. Moreover, by changing suspension properties and EPD conditions set-up such as, deposition time, applied voltage and electrode distance, it would be possible to control the layers quality in terms of morphology, thickness and roughness.…”

In the present work, the effects of deposition time and applied voltage on the quality of cobalt nanoparticle film, deposited on aluminium substrate have been investigated experimentally. Cobalt oxide nanoparticles were produced by laser ablation method. The produced nanoparticles were deposited on aluminium substrate with electrophoretic deposition technique at different applied voltage and deposition time. Produced nanoparticles as well as deposited films were characterized by employing several diagnostics including scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffractometry (XRD), and UV-Vis-NIR spectroscopy. XRD pattern confirmed the presence of the cobalt oxide in all samples. SEM micrographs showed the effective role of applied voltage and deposition time on the morphology of deposited films. By using AFM results roughness, thickness and average particles size of deposited films were measured. Also an optimum point for applied voltage and deposition time were investigated. UV-Vis-NIRspectroscopy determined optical properties of nanoparticles and deposited films.

Electrophoretic deposition method has been developed for the electrodeposition of linear polyethylenimine (LPEI) films. The deposition mechanism is based on the electrophoresis of protonated LPEI-H z , base generation at the cathode surface, charge neutralisation and formation of insoluble LPEI films. Quartz crystal microbalance data, coupled with the results of electron microscopy, showed that deposition rate and film thickness can be varied and controlled by the variation of deposition time and voltage. LPEI films provided corrosion protection of stainless steel substrates. LPEI was used for the dispersion, charging and electrophoretic deposition of TiO 2 , hydrotalcite and MnO 2 particles and fabrication of composite films. Scanning electron microscopy and thermogravimetric analysis showed the formation of composite films, containing 45?4%TiO 2 , 53?1% hydrotalcite and 33?3%MnO 2 in the LPEI matrix. The film thickness was varied in the range of 0?1-4 mm by variation of the deposition time at a constant deposition voltage. The proposed approach paves the way for the fabrication of organic-inorganic composite films combining functional properties of LPEI and inorganic materials.

“…The mixture was blended with a dispersion of single-wall carbon nanotubes (SWCNTs) and placed in an electrochemical cell, where a 3–15 V direct current (DC) potential was applied over a period of time that varied from 1 to 10 min. The process was used to control the particle-polymer deposition rate for the fabrication of metal oxide nanoparticle-polymer films with a thickness that varied from 100 nm to 15 μm [ 67 , 68 ]. Another polymer, poly (3-octylthiophene) (P3OT), has been blended with SWCNTs to fabricate particle-polymer films with enhanced current density [ 69 ].…”

Particle-polymer dispersions are ubiquitous in additive manufacturing (AM), where they are used as inks to create composite materials with applications to wearable sensors, energy storage materials, and actuation elements. It has been observed that directional alignment of the particle phase in the polymer dispersion can imbue the resulting composite material with enhanced mechanical, electrical, thermal or optical properties. Thus, external field-driven particle alignment during the AM process is one approach to tailoring the properties of composites for end-use applications. This review article provides an overview of externally directed field mechanisms (e.g., electric, magnetic, and acoustic) that are used for particle alignment. Illustrative examples from the AM literature show how these mechanisms are used to create structured composites with unique properties that can only be achieved through alignment. This article closes with a discussion of how particle distribution (i.e., microstructure) affects mechanical properties. A fundamental description of particle phase transport in polymers could lead to the development of AM process control for particle-polymer composite fabrication. This would ultimately create opportunities to explore the fundamental impact that alignment has on particle-polymer composite properties, which opens up the possibility of tailoring these materials for specific applications.
