Observation of Percolation-like Scaling - Far from the Percolation Threshold - in High Volume Fraction, High Conductivity Polymer-Nanotube Composite Films

We describe the fabrication of extremely high mass fraction polymer‐nanotube composites displaying very high conductivity. 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 comp...

Zusammenfassung:We describe the fabrication of extremely high mass fraction polymer‐nanotube composites displaying very high conductivity. 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.
