Organic positive temperature coefficient thermistor and manufacturing method therefor

Abstract

An organic positive temperature coefficient thermistor comprising a thermoplastic polymer matrix, a low-molecular organic compound having a melting point that is equal to or greater than 40.degree. C. and less than 100.degree. C. and conductive particles, each having spiky protuberances, is obtained by crosslinking a milled mixture of these components with a silane coupling agent comprising a vinyl group or a (meth)acryloyl group and an alkoxy group. This organic positive temperature coefficient thermistor has sufficiently low resistance at room temperature and a large rate of resistance change between an operating state and a non-operating state, and can be operated at less than 100.degree. C. with a reduced temperature vs. resistance curve hysteresis, ease of control of operating temperature, and high performance stability.
