Suppressing the negative temperature coefficient effect of resistance in polymer composites with positive temperature coefficients of resistance by coating with parylene

Author affiliations

Abstract

One of the problems of polymer thermistors with a positive temperature coefficient (PTC) is a negative temperature coefficient (NTC) effect. This study proposes a parylene coating on thermistors to suppress the NTC effect while maintaining the PTC characteristics. An 800 nm-thick parylene coating suppressed the NTC effect to 11.8%. Electrical impedance spectroscopy revealed that the parylene coating prevented the formation of new conductive paths, which led to the elimination of the NTC effect.
