Mesoscopic shape of MWCNTs. SEM image shows the representative shape of M1, M2, M3, and M4. M1 and M2 meet the rigid random-coil limit. M4 meets the rigid rod limit. M3 is in the intermediate range. Lines are obtained by Eqs. (1) and (2).
MWCNTs networks on the porous substrate. Network made of rigid random coil (M1) and rigid rod (M4). Area inside the drawn circle is defined as the cell area where single MWCNT is located.
Effect of surface concentration and temperature on the surface resistivities of various MWCNT networks.
Surface resistivity of MWCNTs networks with respect to the dimensionless surface concentration. (a) Surface resistivities of networks made from groups M1, M2, M3, and M4. (b) Percolation scaling law fitting.
