Disentanglement of CNTs

Electrical conductivity in nanotube-polymer composites exhibits percolation-type behavior, where the presence of interconnected nanotube network results in a dramatic increase of the electrical conductivity. Physical parameters of composite materials such as electrical conductivity, percolation threshold v ), and critical exponent (t) have been intensively studied to achieve polymer-CNT conductive composites at low filler concentrations. However, as already mentioned, numerous studies show that the percolation threshold and conductivity depend strongly on the polymer type and synthesis method, aspect ratio of CNTs, disentanglement of CNT agglomerates, uniform spatial distribution of individual CNTs, and degree of alignment.
