文摘
Photocatalysis and Fenton reaction treatments were first employed to eliminate the residual surfactants in the single-walled carbon nanotubes (SWNTs) films without destroying the intrinsic structure of SWNTs. The removal of the surfactants was verified by Raman and XPS spectra. After the treatments, the conductance of SWNTs films was enhanced by a factor of 2.5. Taking a SWNTs film with transparency of 90.6% at 550 nm and resistance of 4.3 kΩ/, for example, the sheet resistance decreased to 2.0 kΩ/, while the transmittance increased by 0.3% after the treatment.
