  • Abstract
    Three carbon nanotubes post treatment methods were evaluated for their impacts on film conductivity. Acid treatment was found to be the most impactful treatment for conductivity improvement, with >3 times reduction in sheet resistance for long hour soaking in 9M sulfuric acid. Carbon nanotube sorting with agarose gel method for metallic single walled carbon nanotube enrichment also showed great improvement with ~2.5 to 3 times reduction in sheet resistance by simply enhancing the % M-SWNT from 33% to 60%.
