We compared the electrical conductivity of pristine, purified, cut and oxygen plasma treated single-walled carbon nanotube (SWNT) films. Purified SWCNTs can be obtained through H2O2 and HCl treatment. Cut SWCNTs are obtained by treating purified SWCNTs with piranha solution(4:1 vol/vol, 96% H2SO4/30% H2O2) mixture. And we treated pristine SWNT with oxygen plasma treatment. After pretreatment, SWNT thin films were prepared using vacuum filtration methods. By comparing the electrical conductivity of SWNT films according to defects, length and transmittance, effect of pretreatment on the electrical conductivity of SWNT films was discussed. |
