“…From the corrected value of percolation threshold the other three parameters are evaluated again. 28 Figure 4 also shows a comparison between a microfibrillar structured PP/PA6/CB composite (PP/PA6: 80/20), and a PP/PA6/CB composite (PP/ PA6: 55/45), compression molded at 2508C for 10 min with co-continuous morphology. The compression molding of microfibrillar structured composites was performed at 2008C for 10 min to guarantee the fluidity of PP matrix while the molding temperature was just below the melting temperature of PA6-microfibrils (T m 5 2208C), to prevent from melting of PA6-microfibrils during molding process.…”

ABSTRACT:We have established that the PP/PA6/CB composite with 3D microfibrillar conducting network can be prepared in situ using melt spinning process. CB particles preferably were localized at the interface between polypropylene as the matrix and PA6 microfibrils, which act as the conducting paths inside the matrix. The percolation threshold of the system reduced when aspect ratio of the conducting phase was increased by developing microfibrillar morphology. The effect of annealing process on the conductivity of PP/PA6/CB composite with cocontinuous and microfibrillar morphologies was studied. It was observed that, annealing process forces CB particles towards the interface (2D space) of PP and PA6 co-continuous phases, and percolation threshold and critical exponent of classical percolation theory will be decreased, while the conductivity of conducting composite with microfibrillar morphology was not affected considerably by annealing process at temperatures either higher or lower than the melting point of the PA6 microfibrils.
