摘要: Dense, aligned single-walled carbon nanotubes (SWCNTs) were obtained by nitric acid treatment and the subsequent removal of metal impurities HCl. The highly purified SWCNTs dispersed with sodium dodecyl sulfate in order to obtain a stabilized suspension for spray coating on flexible polyethylene terephthalate (PET) substrate. low sheet resistance resulting thin conductive film PET substrate was due interconnecting networks SWCNT bundles. These bundles formed strong crisscross clustered together well defined channels, thus improving electrical optical properties film. Its varied from 956 472 Ω/square 85% transmittance at wavelength 550 nm. films may be potential candidates display applications.
