▎ 摘　　要

NOVELTY - The present invention describes the method to add graphene or carbon nanotubes in an existing PPTC thermistor compositions (mainly HDPE and carbon black), wherein the weight percentage of graphene or carbon nanotubes is less than or equal to 10 wt% of the composition. Due to the excellent electrical conductivity and physical properties of graphene or carbon nanotubes, it can reduce the resistance of PPTC thermistor and enhance current-carrying ability of PPTC thermistor.
