The Complexity Of Electrically Conductive Coatings

Electrically conductive coatings are used in various facets of industry and also manufacturing. Many of these applications could not be economically produced without the current advancements in conductive coatings.

- Conductive adhesives to electrically link dissimilar materials

- Automobile glass for defrosting and also clarity adjustment

- Automobile component electro-coating

- Innovative Electroplating

- Circuit components-high power capacitors-circuit boards

- Solar cells

- Led lighting

- Touch screens

- Medical electrodes

- Membrane switches

- Electrically conductive ink

- Transducers

Active solar panels that convert sunlight right into electrical energy rely on economical conductive coatings to reduce production costs and make large solar arrays more competitive with typical power generating methods.

Among the more interesting applications of electrically conductive coatings is the production of "smart glass", using electro-chromic technology. Smart glass is a layered glass generated by laminating two pieces of glass above an electrically conductive coating that is photoelectric sensitive. The sandwiched conductive coating is made to darken with the use of a low voltage current. This technology has been utilized for several years as auto dimming automobile mirrors and more recently as "smart windows", house windows that you can set the opaqueness with touch of a switch.

One more use of electrically conductive coatings is the production of recreational sonar transducers. Almost every power boat enthusiast has a "locator" installed somewhere on their boat. Basically, the transducers are a crystal created to vibrate at a certain frequency (Hz) when an electric current is applied; the transducer emits a pulse that travels until it's mirrored back to the transducer by an object such as the lake bottom or a suspended object. Procedure is just like sonar without the audible "ping".

This same technology is needed in GPR (ground penetrating radar or sub-surface imaging). GPR uses much lower frequency and larger transducer arrays. A signal or pulse out of the transducer array permeates the earth to a limited depth-depending on the frequency of the transducer-then reflected back to a control console that perceives the signal. GPR is commonly used for finding buried man made anomalies such as pipes, tanks, cables as well as unmarked graves. Archeologists use it to acquire evidence of past civilizations.

Conductive coatings make all these technologies feasible or maybe economically feasible would be a more suitable term. Without these unique coatings, production of these types of specialized equipment for researchers and the average consumer would cost prohibitive.
