▎ 摘　　要

NOVELTY - A reduced graphene oxide/polyvinylidene fluoride composite material comprises 0.001-3 wt.% reduced graphene oxide with respect to 100 wt.% polyvinylidene fluoride. The composite material has negative temperature coefficient thermistor characteristics. USE - Reduced graphene oxide/polyvinylidene fluoride composite material is used in temperature and pressure-sensitive thermistor sensor (claimed). ADVANTAGE - The reduced graphene oxide/polyvinylidene fluoride composite material has high resistance reduction value based on temperature change. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of reduced graphene oxide/polyvinylidene fluoride composite material; and (2) temperature and pressure-sensitive thermistor sensor.
