Electrical properties of the CNT/HDPE composites and thermistors.
Electrical resistivity (ρ) of the CNT/HDPE composites as a function of (a) CNT loadings and (b) temperature; (c) electrical resistance of the CNT/HDPE thermistors at room temperature; (d) voltage-current curves of the CNT/HDPE thermistors, implying a typical PTC effect induced by applied voltages; (e) hold current and (f) hold voltage of the thermistors as functions of CNT loadings.
