“…Similar structures have also been created on titanium substrates (Urch et al 2006). Tabellion & Clasen (2004) have discussed previous work on the fabrication of large components, free-standing objects, hollow bodies and objects of complex threedimensional shape using EPD of silica nanoparticles in aqueous suspensions. It has been proposed that silica nanoparticulate coatings can be useful model materials to develop reproducible surface topography to influence cellular response (Cousins et al 2004) and EPD is thus a convenient technique to order silica nanoparticles in predetermined patterns.…”

Electrophoretic deposition (EPD) is attracting increasing attention as an effective technique for the processing of biomaterials, specifically bioactive coatings and biomedical nanostructures. The well-known advantages of EPD for the production of a wide range of microstructures and nanostructures as well as unique and complex material combinations are being exploited, starting from well-dispersed suspensions of biomaterials in particulate form (microsized and nanoscale particles, nanotubes, nanoplatelets). EPD of biological entities such as enzymes, bacteria and cells is also being investigated. The review presents a comprehensive summary and discussion of relevant recent work on EPD describing the specific application of the technique in the processing of several biomaterials, focusing on (i) conventional bioactive (inorganic) coatings, e.g. hydroxyapatite or bioactive glass coatings on orthopaedic implants, and (ii) biomedical nanostructures, including biopolymer-ceramic nanocomposites, carbon nanotube coatings, tissue engineering scaffolds, deposition of proteins and other biological entities for sensors and advanced functional coatings. It is the intention to inform the reader on how EPD has become an important tool in advanced biomaterials processing, as a convenient alternative to conventional methods, and to present the potential of the technique to manipulate and control the deposition of a range of nanomaterials of interest in the biomedical and biotechnology fields.

“…All the suspensions were ultrasonicated with a Branson Sonifier W450 (Branson Scientific, Inc., Plainview, NY) to destroy the agglomerates in the suspension and finally degassed at 200 mbar (20 kPa). The green compacts were formed by EPD according to the membrane method from aqueous suspensions [1]. The electrophoresis cell was subdivided into two chambers by a cellulose membrane that was permeable for ions but not for the Al 2 O 3 -particles, which deposit onto the membrane.…”

“…Electrophoretic deposition enables the formation of homogeneous, uniform green microstructures with high density, which can be sintered to transparency. It is a simple and precise technique to synthesize not only monoliths, but also composites with complex geometries [1]. Alumina green bodies were deposited from stabilized aqueous suspensions with and without doping.…”

The optical quality attainable in coarse-grained polycrystalline alumina is severely limited by grain-boundary scattering, which is inherent to non-cubic materials. The optical properties of sub-micrometre polycrystalline alumina are of growing interest triggered by the fact that a decrease in the grain sizes of the final sintered material yields an improvement in the optical quality while the scattering mechanism changes as the grain size becomes comparable with the wavelength of light. To achieve transparent alumina ceramics with a fine-grained microstructure, however, porosity and other defects must be avoided. This necessitates the optimization of processing and sintering procedures. Electrophoretic deposition (EPD) is a colloidal process in which ceramic bodies are directly shaped from a stable suspension by application of an electric field. Electrophoretic deposition enables the formation of homogeneous, uniform green microstructures with high density, which can be sintered to transparency. It is a simple and precise technique to synthesize not only monoliths, but also composites with complex geometries [1]. Alumina green bodies were deposited from stabilized aqueous suspensions with and without doping. Green alumina compacts were evaluated based on their pore size distribution and density. Densification behaviour was characterized by dilatometric studies conducted at constant heating rate. Samples were sintered at different temperatures with subsequent post-densification by hot isostatic pressing. Transparency was evaluated by means of spectroscopic measurements. The measured in-line transmission of the samples at 645 nm was more than 50 % and that is 58 % of the value of sapphire. The influence of dopings on transparency was investigated. The mechanical properties of the samples were tested.

“…For example, the PLD process is a versatile coating technique to fabricate thickness and nanostructure-controlled films with less contamination on a substrate [16,17]. Electrophoretic deposition (EPD) is also a promising room temperature process which exhibits the capability to coat thin/thick films in ambient atmosphere on complex-shaped substrates such as tube, sphere and wire netting [18] and the applicability to any suspensions containing charged particles, i.e., conductive polymers [19], organic, inorganic, or organic-inorganic composites [20,21]. The effective application of the EPD process has been extensively studied for the fabrication of traditional ceramic materials for a long time [22,23].…”

Thin and transparent Mo 6 cluster films with significant optical properties were prepared on indium tin oxide (ITO)-coated glass plates from the suspension of Cs 2 Mo 6 Br 14 cluster precursors dispersed in methyl-ethyl-ketone (MEK) by an electrophoretic deposition (EPD) process. Two kinds of polydimethylsiloxanes (PDMS); i.e., KF-96L-1.5CS and KF-96L-2CS corresponding to the kinetic viscosity of 1.5 and 2 centistokes, respectively, were selected to topcoat the Mo 6 cluster film after the EPD. The influence of the PDMS on the durability, chemical compatibility and light absorption property of Mo 6 cluster films were characterized by means of field-emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet-visible-near infrared (UV-Vis-NIR) spectroscopy. The stabilized PDMS-coated Mo 6 cluster film could be stored for more than 6 months under ambient conditions.
