Abstract: Single-wall carbon nanotube (SWNT) was prepared by d.c. arc discharge method and purified by filtration method. After refluxed in HNO3, the ends of SWNT were opened and oxidized into carboxylate group, which may react with other reagents. For chemical modification of SWNT, the carboxyl terminated SWNT reacted with CH3(CH2)15 NH2 with the aid of the condensation agent DCC to obtain the derivatives of SWNT with the amido-alkyl chain which enhanced the solubility of SWNT in organic solvent. The results of micro IR prove the formation of amido group in SWNT sample(v(C—O)=1 647 cm-1 ). The FT Raman results show that SWNT sample preserve its structure after the condensation reaction( ωr=181 cm-1 ).
