| Abstract: | An electrochemical sensing platform was developed based on the composite of ionic liquid(1-butyl-3-methylimidazolium dicyanamide,]N(CN)2,IL),multi-walled carbon nanotubes(MWCNTs) and polymeric matrix(chitosan,CS).Scanning electron microscope images showed that MWCNTs had a good dispersibility in the MWCNTs-IL-CS composite and formed a relative smooth film with unique structure.Electrochemical studies indicated that the MWCNTs-IL-CS composite provided a synergistic improvement on the electrochemical oxidatio... |
