CONDUCTIVE ELASTOMERS AND METHODS FOR FABRICATING THE SAME

摘要

Several different types of electrically conductive elastomers are disclosed along with the methods for their fabrication. In one particular embodiment, a layered composition is disclosed which comprises a substrate, a first layer, and a second layer. The substrate is formed of a non-conductive elastic material and it has an outer surface. The first layer, which is formed with a non-conductive elastic material, is grafted to the outer surface of the substrate. The second layer, which is formed with a non-conductive elastic material having a quantity of conductive flakes interspersed therein, is grafted to an outer surface of the first layer. The second layer can further be formed with a quantity of rounded or jagged conductive particles interspersed in the non-conductive elastic material such that some of the conductive particles are present along an outer surface of the second layer. Alternatively, a quantity of rounded or jagged conductive particles may be imbedded in an outer surface of the second layer.
