Abstract: In order to realize chemical modification on carbon nanotube and lactose so that they react with each other to become new bioactive materials, carbon nanotubes were first carboxylated using oxalyl chloride and azodiisobutyronitrile(AIBN) respectively. Then lactobionic acid was reacted with ethylene diamine. Secondly, the two modification products were made to react and N,N'-lactobionyl carbon nanotube formyl/isobutau ethylene diamines were prepared. They were finally characterized by FT-IR spectroscopy.
