An integral composite structure having predetermined electrically conductive networks on a non-conductive planar or non-planar support structure produced by the combination of a slurry of electrically conductive materials having a fluid carrier which includes an evaporative fluid and an elastomeric substance in which particles of an electrically conductive material are contained, the fluid carrier being chemically reactive with the material forming the relatively non-conductive support structure to secure one to the other, and upon evaporation of the evaporative portion of the fluid carrier, the unevaporated portion of the slurry formed of the elastomeric substance and the electrically conductive particles form a solid which is both flexible and electrically conductive and a method for producing same, including the steps of introducing the slurry into a container, the container having at least a portion of the wall forming the container consisting of an elastomeric material having at least one normally closed orifice therein arranged in a desired pattern, which without the application of pressure to the slurry remains closed, juxtapositioning the wall having the orifice therein relative to the support structure upon which the slurry is desired to be deposited upon, pressurizing the slurry within the container to force the slurry through the normally closed orifice with sufficient pressure to force the slurry into inlet of the orifice passageway in the elastomeric material, displacing the elastomeric material surrounding the orifice and thereby opening the normally closed orifice and causing the slurry to flow through the orifice and to exit the orifice outlet, depositing the slurry exiting from the outlet of said at least one orifice onto the electrically non-conductive support structure in the desired pattern, allowing the slurry to chemically react with the material forming the support structure and to create a bond therebetween, and then evaporating the fluid carrier to leave a flexible, solid residue which is electrically conductive and is integrally secured to the support structure to form an integral composite structure having predetermined electrically conductive networks.
An integral composite structure having predetermined electrically conductive networks on a relatively non-electrically conductive preformed support structure, said composite structure being formed by the combination of a slurry containing electrically conductive materials having a fluid carrier which includes an evaporative fluid and an elastomeric substance in which particles of an electrically conductive material are mixed, said fluid carrier containing elements which are chemically reactive with the material forming the relatively non-electrically conductive preformed support structure so that following the combination of the slurry with the preformed support structure the fluid carrier reacts chemically with the preformed support structure to form a bond therebetween and upon evaporation of the fluid portion of the ink, a residue remains forming a flexible and electrically conductive material arranged in a desired pattern secured to the preformed support structure.
A method for forming an integral composite structure having predetermined electrically conductive networks on a non-conductive preformed support structure which is formed by the combination of a relatively non-conductive ink of electrically conductive materials having a fluid carrier, the fluid carrier having an evaporative fluid and an elastomeric substance in which particles of an electrically conductive material are suspended, the fluid carrier additionally containing elements which are chemically reactive with the material forming the relatively non-conductive preformed support structure so that following the combination of the ink with the preformed support structure the carrier reacts chemically with the preformed support structure to create a bond therebetween and upon evaporation of the evaporative portion of said carrier leaves an flexible electrically conductive residue arranged in a desired pattern:
