ABSTRACT:
Disclosed is a composite temperature-sensitive element having temperature self-controlling characteristics, which comprises graphite or carbon black, a lowly dimensional substance composed mainly of a crosslinked polymer and a linear polymer, and optionally, an inorganic compound, said lowly dimensional substance and said inorganic compound being conjugated with the graphite or carbon black. In this temperature-sensitive element, the change of the resistance value with the lapse of time is very small even when the element is repeatedly used, stable temperature-electroconductivity characteristics are manifested, there is no risk of local super-heating, and temperature self-detecting and controlling functions are manifested at various stages as the sensor of the molecule level.
Furthermore, this temperature-sensitive element is pliable and shows an excellent elasticity even at the temperature elevation, and the temperature-sensitive element has properties of a flexible elastomer having an appropriate rigidity and can be processed into various shapes. Moreover, the element can be easily prepared at a low cost and it is expected that the element will be widely used in various fields.
