Caption : fig. s1. frequency dependences of the directly measured (total) dielectric loss for every sample.

File Name : fig. s2a.tif

Caption : fig. s2. (a) the fitting of data above percolation threshold gives μ=0.19.

File Name : fig. s2b.tif

Caption : fig. s2. (b) the fitting of data (10.87-0.22.21 wt%) gives s=0.01. neither can be explained neither by the static nor by dynamic percolation model.
