ABSTRACT:
A high-velocity spray nozzle is used to physically embed conductive particles into the surface of a non-conductive substrate, thereby rendering it electrically conductive. In contrast to existing, chemically based alternatives, the method offers the use of a dry process with no chemical baths and associated environmental concerns; the ability to produce localized modifications, only in areas where actually required; the use of simple materials, such as air and powdered graphite; and a potential cost savings. Methods of modifying localized areas of the underlying substrate are also disclosed.
