On the nano-filler percolation network in polymer nanocomposites
MetadataShow full item record
With addition of very low loading of high-aspect-ratio nano-fillers in polymers, the physical properties of polymer nanocomposites can be greatly improved. In the paper, the role of nano-filler percolation networks in polymers is discussed. The main focus is on the estimation of two key parameters: percolation threshold and critical exponent, where the former is an optimal volume fraction of nano-fillers and the latter reflects the variation of physical properties such as permeability, flammability and conductivity near the percolation threshold.
