Functionalization of colloidal particles based on the use of polyelectrolytes and heterocoagulation was combined with electrophoretic deposition (EPD), with the aim of depositing titania-polystyrene (TiO(2)-PS) composite particles on Ti6Al4V substrates. The composite particles were obtained by heterocoagulation of TiO(2) nanoparticles on the surface of monosized polystyrene beads of 4.6 microm ...

In this research work, the original 45S5 bioactive glass was modified by introducing zinc and/or strontium oxide (6 mol%) in place of calcium oxide. Sr was added for its ability to stimulate bone formation and Zn for its role in bone metabolism, antibacterial properties, and anti-inflammatory effect. The glasses were produced by means of melting and quenching process. SEM and XRD analyses evide...

Electrophoretic deposition (EPD) can occur as a cataphoretic - the coating is deposited on cathode, and anaphoretic anode. The primary purpose of EPD to obtain compact uniform organic/inorganic coatings desired thickness adhesion metal surfaces by applying an electric field particles precursor. basic principles for concerning fundamental explanations considerations practical parameters process ...

This investigation describes for the first time application of carbenoxolone electrophoretic deposition (EPD) different carbon materials, polytetrafluoroethylene (PTFE) and their composite films. Carbenoxolone is a versatile biosurfactant, which adsorbs on materials due to its amphiphilic structure allows charging dispersion. Moreover, exhibits film-forming properties, are investigated in exper...

This investigation addresses the need in biocompatible biosurfactants for electrophoretic deposition (EPD) of biomaterials. It is motivated by unique multifunctional properties bile acid salts. Sodium cholate CHOLNa a primary salt, which can solubilize and disperse different functional The EPD mechanism pure involves electrophoresis (EP) CHOL− micelles, their discharge gelation cholic (CHOLH) t...

Thin films of polyethylenimine-stabilized Sb2S3 are prepared via electrophoretic deposition (EPD), showing strong adhesion between the deposited layers and underlying substrate, with being crystallized annealing. For amorphous films, thicknesses can be freely tuned from 0.2 to 1 μm, shrinking 0.1–0.5 μm when crystallized, while retaining a crack- defect-free surface, thus not impacting their go...

dye sensitized solar cell was fabricated from a double layer photoanode. first, tio2 nanoparticles  were synthesized by hydrothermal method. these tio2 nps were deposited on fto glasses by electrophoretic deposition  method in applied voltage of 5 v and epd time of 2.5-10 min. then tio2 hollow spheres (hss) were synthesized by sacrificed template method with carbon spheres as template and ttip ...

having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. finding a white-box mathematical model for weight vs. time curves of electrophoretic deposition (epd) using large and small signal analysis has been studied thoroughly in the present investigation. weight-time curves of nano-mullite suspension have been tr...

We report on an electrophoretic deposition (EPD) method that is suited for the preparation of both ZnO thin films and micropatterns. By applying small DC voltages between a Cu electrode and a conductive Si substrate, submersed in a suspension of ZnO quantum dots, we can cover entire substrates with ZnO layers of a tuneable thickness ranging from a few monolayers to 200 nm. The deposition occurs...

Ceramic-metal composites have drawn considerable interest due to their mechanical, thermal and wear-resistant capabilities. High temperature processing of these materials when they are employed in electronic circuitry is not desirable, since elevated temperatures can irreversibly affect physical properties of the produced components. Wet chemical methods have potential advantages because they d...
