摘要:
This invention is directed to a polymer thick film transparent conductive composition with haptic response capability that may be used in applications where thermoforming of the base substrate occurs, e.g., as in capacitive switches. Polycarbonate substrates are often used as the substrate and the polymer thick film conductive composition may be used without any barrier layer. Depending on the specific design, the thermoformable transparent conductor may be below or on top of a thermoformable silver conductor. Thermoformable electric circuits benefit from the presence of an encapsulant layer over the dried polymer thick film conductive composition. The electrical circuit is subsequently subjected to an injection molding process.
