Studies on the selective localization of multi-walled carbon nanotubes in blends of poly(vinylidene fluoride) and polycaprolactone

Conductive and dielectric materials based on PVDF have attracted considerable interests from the scientific community and industry, owing to their wide use in electrical and electronic industry The main advantages of PVDF-based composites are good mechanical flexibility and tunable properties for making different types of devices. Due to the insulating properties of PVDF, conductive fillers, especially nanoparticles such as CNT, carbon black, graphene and metal particles, need to be added to the matrix. CNT/PVDF composites are one of the most important types of conductive materials because of the excellent electric and mechanical properties of . Solution mixing CNT with PVDF, involving sonication, is usually preferred in the lab studies of CNT/PVDF composites and relatively low percolation threshold of CNT could be achieved. But solution mixing is a solvent-consuming process, which is not suitable for industrial production. CNT/PVDF nanocomposites prepared by melt compounding, which is a feasible way for large-scale pro-77
