Abstract

Piezoresistance of high density polyethylene/graphite (HDPE/GP) semi-conductive composites was studied through measuring the resistance change under uniaxial pressure. The results show that there is a marking pressure dependence of the conductivity in the HDPE/GP composites. Under constant pressures, the time-dependent resistivity is an outstanding characteristic for the composites. The breakdown and rebuild process of the conductive network under pressure may be responsible for the pressure- and time-dependence of resistivity.
