We characterize 10-nm outer diameter multi-walled carbon nanotubes (powder and dispersion), which will be used for the preparation of conductive layers on polycarbonate (PC) substrates. The optical, electrical, and mechanical characterization of the spin-coated deposited layers is shown and compared with results obtained for layers deposited in borosilicate glass substrates. In both glass and plastic, the layers have shown transmittance higher than 78% in the visible range and have passed the tape and pencil standard tests for adherence and hardness, respectively. However, the sheet resistance presented by layers deposited on PC is still much superior to that of layers deposited on glass and sintered at higher temperatures. Nevertheless, the results obtained still allow the use of such layers in antistatic applications.
