▎ 摘  要

NOVELTY - Elastomeric conductive nanocomposite comprises a mixed polymer matrix comprising an elastomer and a polyether, graphene nanoparticles in the form of nanosheets in an amount of 0.1-5 wt.%, and 0.5-10 wt.% iron metal nanoparticles, where the nanocomposite has a nonlinear relationship between resistivity and temperature in the region of 25-180degrees Celsius characterized by an exponential increase reaching a peak resistivity followed by an exponential decrease, and the nanocomposite has a peak resistivity of 2500-18000 ohm cm at 100-180degrees Celsius. USE - The elastomeric conductive nanocomposite is useful for forming heater and thermistor. ADVANTAGE - The nanocomposite has nonlinear relationship between resistivity and temperature. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) A heater comprising the above-mentioned nanocomposite sandwiched between metal electrodes. (2) A thermistor comprising the above-mentioned nanocomposite.
