| Abstract: | Conductive properties of polymer composites filled with two kinds of carbon materials(carbon nanotubes and carbon black or graphite) are introduced and the conductive mechanism is expounded.The calculating model of electrical percolation threshold based on linear blending rule and excluded volume theory are separately given and the difference between calculating values and experimental data is discussed.Using the excluded volume theory,a calculating model of percolation threshold of polymer filled with two ... |
