Synopsis
Amide bond formation between carboxylated multi-walled carbon nanotubes (MWCNT-COOHs) and a glass surface with a water-soluble condensing agent in aqueous media was examined to make a transparent conductive material. The condensing agent used was DMT-MM (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride). The extent of immobilization depended on the DMT-MM content in solution; and an optimum concentration of DMT-MM was found to exist. Finally, a mechanism for the variation of the extent of immobilization as a function of DMT-MM content was proposed.

Key words: multi-walled carbon nanotubes, DMT-MM, condensation
