Descrição: The studies of electrical properties of thepolyisoprene (PI) matrix/high structure carbon black (HSCB)composites (PCBC) with various concentrations (8, 9, 10 and 11mass parts) of filler have been carried out in the temperatureinterval of 90K-330K. In this paper we focus on the investigationof direct current (DC) conductivity in a low-temperature regionwith negative temperature coefficient of resistivity (NTCR). Ithas been proven that variable range hopping (VRH) conductionis dominated by hopping of carriers among localized states in alow-temperature range. At higher temperatures the nearestneighbour hopping (NNH) conductivity or constant rangehopping charge transport takes place. The reversibility as well assmall hysteresis of resistance change versus temperatureindicates prospective temperature sensor application for PCBC
