Enhancing the conductivity of isotactic polypropylene/polyethylene/carbon black composites by oscillatory shear
The influence of oscillatory shear on the conductivity of the isotactic polypropylene/polyethylene/carbon black composites is studied. It is found that the oscillatory shear under high strain amplitude can enhance the conductivity of the ternary composites with a HDPE/CB concentration in the percolation region. This is related to the fact that the high-strain oscillatory shear can improve the continuity of the conductive HDPE/CB phase in the composites. This finding has not been previously reported, and it may be used in industry to improve the conductivity of the ternary conductive composites with a low filler loading.
