Functionalization of Carboxylated Multi-wall Nanotubes with 3H-Purin-6(9H)-one

In this research, the chemical functionalization of carboxylated multi-walled carbon nanotubes (MWNT-COOH) by 5-amino-1H-imidazole-4-carboxamide, have been investigated. MWNT-3H-Purin-6(9H)-one is obtained through. MWNT-Amide reaction with POCl3 after 72h, which is confirmed by FT-IR, SEM, TGA, and elemental analysis. acid-chloride-functionalized CNTs are used to attach glucosamine [1] and didecylamine [2]. Also, the amidation of CNTs carried out with aromatic amines [3]. In this research, we investigated the formation of MWNT-3H-Purin-6(9H)-one, on the MWNT in addition to developing the amidation of MWNT with bifuntional aromatic amine. The products were characterized by FT-IR, SEM, TGA, and elemental analysis. Synthesis route of modified MWNT-COOH is showned
