If it is assumed that f is not affected by the presence of PEDOT PSS, i.e., = 2/ there is no theoretical change in the percolation threshold... 

The values for the theoretical predictions were determined using Equation 6.3 with values for f of 1 and 2 nm. These predictions model a gradual decrease in the overall percolation threshold upon the addition of the SWCNTs. From the experimental data a steep drop in the percolation threshold with the introduction of a small fraction of SWCNTs can be observed. The gradient of this drop is larger than that observed for the addition of PEDOT PSS. This could...
