Recent progress on thermo-electrical properties of conductive polymer composites and their application in temperature sensors

Abstract

Upon heating, the inner conductive pathway inside the conductive polymer composites (CPCs) changes, thus causing the change in electrical resistance. This thermo-electrical dependence of CPCs can be utilized to design CPCs-based temperature sensors. Herein, we systematically review the recent progress on CPCs-based temperature sensors, as well as their mechanisms and applications in different fields. Finally, the question and challenge of CPCs-based temperature sensors are also discussed.
