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.
