Amide Bond Formation between Carboxylated Multi-Walled Carbon Nanotubes and Glass Surface by Using Carbodiimide Condensing Agent and Triazole Derivatives

Abstract

Amide bond formation between carboxylated multi-walled carbon nanotubes (MWCNT-COOHs) and aminated glass surface has been studied to make transparent conductive device. Examining the condensation reaction between MWCNT-COOHs and glass surface under various conditions, it has been found that MWCNT-COOHs are immobilized on the surface by reaction using a carbodiimide and a triazole. The MWCNT layers formed are not easily detached; the interaction between MWCNTs and glass surface is quite strong, implying formation of chemical bonding. Immobilization of MWCNTs on the surface is confirmed also by scanning electron microscopy. Electric conductivity of MWCNT-coated glass has been preliminarily measured.
