Conductive coatings for

Deposition of thin films is used to change the surface properties of the base material, the substrate. For example, optical properties such as transmission or reflection of lenses and other glass products, can be adjusted by applying suitable coating layer systems. Metal coatings on plastic web produce conductive coatings for film capacitors. Polymer layers on metals enhance the corrosion resistance of the substrate.

The author conducted some of the earliest re.search in the UK for the UK DoT on conductive coatings for cathodic protection (Geoghegan el si., 1985), The first UK trial was designed and installed by the author on Melbury House above Marylebone Station in London for British Rail in... 

Conductive Coatings for Electromagnetic Shielding and Static-Dissipating Appiications. In addition to the RF electrochromics research discussed above, EAPs are also used as conductive coatings on textiles for radarabsorbing materials (RAMs) (420). Polypyrrole and PANI are both examples of EAPs used in composite formulations as RAMs (420,422). 

Even small scratches can destroy the performance of conductive coatings. For example, suppose that a single (inside) conductive coating has been used to achieve 50 dB of shielding effectiveness in the 50 MHz-1 GHz spectrum. Further, suppose that a screwdriver accidentally developed a 4-in. (102-mm) x 10-mil (0.25-mm) scratch. From Eq. (11.12), the resulting shielding effectiveness to the seventh harmonic of a 90-MHz onboard clock is... 

A study of various coating devices was conducted several years ago to identify the best conductive coating for high resolution SET taken using a TEM (with a scanning attachment) with a... 

Besides e-beam lithography, a closely related application of these CP conductive coatings is of course SEM mask metrology and prevention of charging during SEM inspection. Both these fall under the category of conductive coatings for ESD and other applications, discussed in Chapter 19.
