چکیده انگلیسی
In the current article we present an original attempt to investigate the development of the percolative electroconductive structure of PNCC during vulcanization. The “in-situ” measurements of electrical resistivity have been performed to evaluate the development of the percolative carbon black structure in PNCC directly during the vulcanization process. The measurements of the piezoresistive effect for samples with different durations of vulcanization time have been made. The samples have been studied using SEM and dielectric spectroscopy. To perform SEM analysis the samples were frozen in liquid nitrogen and then fractured. Four different processes that affect the formation of the percolation network of high-structure carbon black (HSCB) in PNCC during vulcanization phase have been identified.
