Optimisation of Collagen Films Produced via Pulsed Current Electrophoretic Deposition
Electrophoretic deposition (EPD) has been used for the deposition of insoluble collagen type I in aqueous suspensions. In this process, two electrodes are immersed in an aqueous collagen suspension and a voltage is applied. The charged particles in the suspension move towards the oppositely-charged …

Production of Dermal Inspired Collagen Architectures by Lyophilisation and Electrophoretic Deposition
… to mimic the native epidermis, direct current electrophoretic deposition (DC-EPD) was investigated as a method to produce collagen membranes. DC-EPD was applied to suspended collagen scaffolds to produce well-adhered, continuous, and defect-free scaffold-film bilayers. Carbodiimide crosslinking …

Investigation of electrophoretic deposition as a fabrication technique for high performance composites
Electrophoretic deposition (EPD) is a colloidal processing method for the deposition of materials from charged nanoparticles suspended in solution with the application of an external electric field. It is an increasingly popular manufacturing method for engineered materials because of its low cost, …

Production of Multi-layer and Cell-Containing Collagen Membranes Using Direct Electrophoretic Deposition
… Collagen membranes can be produced using electrophoretic deposition (EPD). A voltage is applied to an aqueous suspension between two electrodes, causing movement of charged particles to form a dense membrane in a variety of shapes and sizes. The films need to be removed easily from their …

Collective behavior of colloidal suspensions under electric fields and confinement
… an application of these studies, we investigate electrophoretic deposition, a multiphysics phenomenon, as a method for the assembly of colloidal suspensions. Although the basic mechanisms in electrophoretic deposition are well-known and have been studied extensively, a detailed, quantitative …

A Study on the Use of Inverse Opals Composed of Zinc Oxide Aggregate Popcorn Particles to Improve the Efficiency of Dye- Sensitized Solar Cells
… known as ZnO popcorn particles. Subsequently, electrophoretic deposition (EPD) is used to assemble the popcorn particles into an inverse opal structure. This is a unique application of EPD, which has previously been used to infiltrate nanoparticles (d ≤20nm range) Into opal templates, …

Surface forces during electrophoretic assembly of micron scale silica particles
… of particles far from the electrodes and their deposition onto the working electrode during application of a DC potential. The role of electrode reversibility was investigated and the performance of the as-deposited electrodes was improved by electrolytic plating of platinum. Particles were also …

Development of Solution-Processed Stable Silver Nanowire Networks for Transparent Electrodes
… or Reduced Graphene Oxide (RGO). In particular, electrophoretic deposition and layer-by-layer deposition were actively explored as processing techniques to achieve AgNW networks protected by thin films of GO or RGO. A first process is developed to fabricate a transferrable AgNW network protected …

Fabrication and optimization of light emitting devices with core-shell quantum dots
… "core-shell" QDs. The first part studies the electrophoretic deposition (EPD) of CdSe/ZnS QDs. QD-LEDs conventionally utilize a QD lm that is deposited via spin-casting, a reliable but highly unscalable technique for the deposition of thin, smooth films of QDs for QD-LED applications. …

Controlled Surface Layer Deposition for Steel Surface Hardening
Electrophoretic deposition (EPD) of Ti on low carbon steel followed by heat treatment, which was done at 600-1400 degree celsius for 1 h or 9 h under Ar (sintering) and 5% H2-N2 (nitridation), were used for surface hardening. The coarse Ti particles (≤50 μm) were suspended in ethanol using the …
