Deposition methods electrophoretic

The main deposition methods of NS-Ti02 onto stainless steels are cathodic arc deposition [532], electrophoretic deposition [533], anodic spark deposition (ASD) [534], the sol-gel method [535, 536], atmospheric pressure metal organic CVD (AP-MOCVD) [537, 538] and radio frequency (RF) magnetron sputtering [539]. Preparation methods and applications of NS-Ti02 thin films on stainless steel have been summarized in Table 15. 

Thin film devices can be fabricated by an electrophoretic deposition technique. In the electrophoretic deposition method, the materials are applied as colloidal particles in a non-solvent. By subjecting the particles to an electrophoretic force, a nanostructured film is formed. Drying of the film is done under non-solvent conditions in order to keep the structure. 

One-step electropolymerization deposition processes are envisaged as the most interesting deposition methods in view of potential technological applications. For this reason, there is a growing interest in the integration of materials obtained in such way to obtain multifunctional nanostructured composites and hybrid materials. The selective localization through electrophoretic deposition of nanotubes at the interface of polymers to obtain flexible, transparent and conductive materials could represent a novel approach. 

Similarly, catalyst coatings can be used to produce MSs via thin film gas phase deposition, with chemical (up to 10 pm thickness) and physical vapour deposition methods (< 1 pm) typically used to deposit metals and metal oxide thin-fihns. Other methods such as electrophoretic deposition of alumina, ZnO, Ce02 and Zr02 coating layers inside the microreactors are also used (Cybulski and Moulijn, 2006 Hessel et al., 2005c).

Since, CS can be dissolved in acidic aqueous solutions, it can be coated on metal surface, such as titanium via solution casting method [89]. Similarly, a coaling of CS and gelatin was prepared on titanium by electrophoretic deposition method. The CS-gelatin coating exhibited good mechanical properties, while human osteoblast cells also showed... 

Although the nanowires synthesized using the template method are usually polycrystalline, recent studies have revealed that it is possible to synfliesize single crystals of nanowires by carefully controlled conditions. For example, Neumann and co-workers have demonstrated that pulse electrodeposition could be used to selectively grow either single-crystalline copper nanowires [56]. In recent work, Cao and co-workers discovered that titanium nanowires, obtained from the electrophoretic deposition method, became single crystals once their diameters had been reduced below 15 nm [57]. 

In recent years titania has been used as photocatalysts mostly in the form of thin films. If titania thick films are prepared in a simple process, the application field is expected to expand. Electrophoretic sol-gel deposition method has been applied to preparation of titania thick films. In preparation of titaina particles, the particles tend to aggregate in the heat treatment process and the re-dispersion of the particles is difficult. However, hydrothermal treatment has been found to prevent the titania particles from aggregating and titania thick films can be prepared by the electrophoretic sol-gel deposition using these hydrothermally treated particles (Sakamoto, 1998). 

A number of assembly methods employ self-assembly of nanoparticles at the air-water interface. Monolayers (and subsequent multilayers) can be formed at the interface due particle interaction and transferred to a solid substrate by controlled dip-coating and vertical deposition methods similar to Langmuir-Blodgett film deposition [81-86]. Regular monolayers of polymer colloids can also be assembled via an electrohydrodynamic route, whereby electrophoretically deposited particles between two electrodes can be manipulated to cluster in the presence of an electric field. On application of an AC or DC field, contrary to electrostatic norms, the like-charged particles are observed to coalesce producing large close-packed 2D crystalline domains [87].

Over the past few years, a large number of experimental approaches have been successfully used as routes to synthesize nanorods or nanowires based on titania, such as combining sol-gel processing with electrophoretic deposition,152 spin-on process,153 sol-gel template method,154-157 metalorganic chemical vapor deposition,158-159 anodic oxidative hydrolysis,160 sonochemical synthesis,161 inverse microemulsion method,162 molten salt-assisted and pyrolysis routes163 and hydrothermal synthesis.163-171 We will discuss more in detail the latter preparation, because the advantage of this technique is that nanorods can be obtained in relatively large amounts. 

Nanocarbons can also be deposited onto surfaces via electrochemistry, such as electrophoretic deposition described earlier. A method for one-step electrochemical layer-by-layer deposition of GO and PANI has been reported by Chen et al. [199]. A solution of GO and aniline was prepared and deposited onto a working electrode via cyclic voltammetry. GO was reduced on the surface when a potential of approx. -1 V (vs. SCE) was applied compared to the polymerization of aniline which occurred at approx. 0.7 V (vs. SCE). Repeated continuous scans between -1.4 to 9 V (vs. SCE) resulted in layer by layer deposition [199]. A slightly modified method has been reported by Li et al. who demonstrated a general method for electrochemical RGO hybridization by first reducing GO onto glassy carbon, copper, Ni foam, or graphene paper to form a porous RGO coating [223]. The porous RGO coated electrode could then be transferred to another electrolyte solution for electrochemical deposition, PANI hybridization was shown as an example [223].
