The SWCNTs films deposited on the flexible substrate using dip-coating. The major issue was studying the time and temperature of sulfuric acid effect on the purification of SWCNTs. The post-treatment of etching dispersion and how to affect the optical and sheet resistance were always considered. The results showed that the sheet resistance of SWCNTs with 12 hrs purification was higher than that without purification, but over 12 hrs the sheet resistance was lower than that without purification. The sheet resistances of SWCNTs at purification temperature of 160°C and 100°C were higher than as-prepared SWCNTs, and the lowest sheet resistance of SWCNTs at purification temperature of 120°C. Simultaneously, the dispersion combined with both the functional group consisting of acetic acid (-COOH) could make SWCNTs more purify and reduced the amorphous carbon. Purification of sulfuric acid at temperature of 120°C and time of 24 hrs had the good performance on optical and electricity for SWCNTs film and the sheet resistance of SWCNTs film could reach 781 Ω/sq. at transmittance of 70%. This study successfully explained the mechanism of the purification of the dispersing and acid destroying for SWCNTs by using Raman spectrum. An optimized acid purification was used to improve the transparent and electricity on the flexible substrate with SWCNTs.
