Carbon nanotubes (CNTs) having excellent electrical conductivity have been used for commercial product such as transparent conducting film. However, its industrial success looks delayed, as one of the reasons, due to its unexpectedly lower conductivity. Supercritical fluid (SCF) was treated to CNT for enhancing debundling without chemical modification on CNT. Transparent conducting film of CNT was prepared using anodized aluminum oxide disc with pore size of 0.2 μm. The surface resistance of the film was measured as a function of its optical transmittance, which was compared to Near-IR and Raman analysis. It will be proved that SCF treated CNT exhibits longer in length, less damaged, and more debundled. |
