Abstract
-
The electrical resistance of carbon nanotube networks (NNs) prepared from combinations of gellan
gum, xanthan gum, Triton X-100, SWNT and MWNT is reported. It is demonstrated that the NN
conductivity can be obtained by analysing the resistance of two overlapping NN as a function of their
overlap distance. Unexpectedly, the connectivity between two overlapping NN was found to scale with
the electrical conductivity over 4 orders of magnitude. Insights into the dependence of inter-NN contact
on applied pressure were obtained.
