Coating conductance

Electrostatic spraying is used in shops to coat conductive objects. It is very useful for odd-shaped objects such as wire fence, cables, and piping. An electrostatic potential of 60,000 volts on the object attracts oppositely-charged paint particles the spray can wrap around and coat the side of the object opposite to the spray gun. This technique produces very uniform finishes and has the least paint loss of the three methods. However, it is slow, requires expensive equipment, produces only thin coats, and is sensitive to wind currents. 

The following statement appears consistently on the details and will determine the choice of all materials including the basic building construction system chosen, special floor coatings, conductive flooring, interior finishes and construction sealants. 

Usually the nanotube arrays have been made from a titanium thick film or foil, in which case the resulting nanotubes rest upon an underlying Ti substrate as separated by a barrier layer. The nanotube arrays have also been fabricated from a titanium thin film sputtered onto a variety of substrates, such as silicon and fluorine doped tin oxide (FTO) coated conductive glass. This extends the possibility for preparing technical catalysts by deposing a thin Ti layer over a substrate (a foam, for example) and then inducing the formation of the nanostructured titania film by anodic oxidation. ...

Ionic conductivity can be found in polyelectrolytes such as the salts of polyacrylic acid, sulfonated polystyrene or quaternized polvamines (ion-exchange resins). When dry, these materials have low conductivities. However, in tiie presence of small amounts of polar solvents or water—some of these polyelectrolytes are somewhat hygroscopic electrical conductivity can be observed. The currents are earned by ions (protons, for instance). Such systems can only be used in cases where very small currents are expected. Large currents would result in observable electrochemical changes of the materials, In applications as antistatic electricity coatings, conductivities of 10-b ohm-1 cm-1 are sufficient,...

The stabilities of polypyrrole-coated conductive fabrics were highly dependent on the doping counterion as well as the polymerization conditions. The rate of degradation showed a diffusion controlled kinetics at high temperatures. The room temperature half-life for the most stable conductive fabric was estimated to be about five years [129].

This paper has dealt exclusively with SAW sensors that exploit the mass sensitivity of the device to achieve chemical vapor detection. Schemes to exploit the SAW sensitivity to coating conductance changes (17) or elastic modulus changes should afford new opportunities for imaginative chemical vapor sensor designs. Finally, the field of liquid phase chemical analysis may also yield to surface acoustic wave devices that utilize plate waves and horizontally polarized shear waves to minimize acoustic losses in the liquid (18).
