Abstract:

Phase I work demonstrated temperature sensors formed from polyacrylonitrile and similar polymers which could be applied from solution onto a substrate, then subsequently ion implanted to have conductivity in the kiloohm to megaohmsquare range. If desired, the films could be patterned before implantation to small geometries by lithographic procedures. The resulting films had a large, negative temperature coefficient of resistance, and the resistance-temperature response was reproducible and retraceable within experimental error over multiple cycles. The films were extremely durable and solvent-resistant. A quasi-one dimensional hopping mechanism for conduction was indicated from the conductivity versus temperature and conductivity versus pressure measurements.
