Observation of percolation-like scaling - Far from the percolation threshold - In high volume fraction, high conductivity polymer-nanotube composite films
The fabrication of extremely high mass fraction polymer-nanotube composites displaying very high conductivity is described. Contrary to general expectations, the conductivity displays percolation-like scaling for all mass fractions from 22 % right up to 100 %. These are among the most conductive composites ever demonstrated.
