Percolation characteristics of multi-polymer composites with different ratios of nanocarbon fillers
We have investigated the concentration and thermal dependences of electrical conductivity of multi-composites with different ratios of two nanocarbons. The concentration curve consists of quasi-dynamic and static percolation threshold, two saturation curves. A synergistic effect is observed for both new multi-composites, but in a certain range. We think that the value of percolation threshold, the height and width of the conductivity saturation in multi-composites are influenced by many factors: the concentration of nanocarbons, the number and size of carbon nanotube (CNT) agglomerates and single CNT particles, the different ratio of the number of longer CNT particles to short.
