Abstract EN
Polyvinyl chloride- (PVC-) based nanocomposites containing nanosized graphite and nickel nanoparticles (GN) as conductive fillers to achieve positive temperature coefficient of resistance (PTCR) thermistors and self-regulating heater function have been successfully fabricated.
The microstructure of the foliated graphite and nanocomposites was examined by scanning electron microscopy (SEM).
The effect of GN content on the static electrical conductivity, carrier's mobility, and number of charge carriers of the nanocomposites was studied.
The applicability of nanocomposites as PTCR thermistors was examined by monitoring the conductivity as a function of temperature.
It is found that the conduction mechanism in PVC/GN nanocomposites is governed by tunneling mechanism.
Also, the applied voltage versus current and temperature were studied to check the applicability of composites as self-regulating heater.
The results show that the PVC/GN nanocomposites might have potential applications in PTCR devices, self-regulating heater, and temperature sensors.
