摘　　要：Multiple-walled carbon nanotubes were functionalized by cycloaddition of dichlorocarbene.The chemical modification was performed by using chloroform and sodium hydroxide.Various phase transfer catalysts were used to increase the efficiency of the reaction.Benzyltriethylammonium chloride used as phase transfer catalyst could highly enhance the effect of functionalization.Elemental analysis was used to evaluate the degree of functionalization.Characterization was performed using scanning electron microscopy（SEM）and transmission electron microscopy（TEM）.Fourier transform infrared spectroscopy（FTIR）and energy-dispersive X-ray spectroscopy（EDS）were used to confirm the resulting material.Multiple-walled carbon nanotubes were functionalized by cycloaddition of dichlorocarbene.The chemical modification was performed by using chloroform and sodium hydroxide.Various phase transfer catalysts were used to increase the efficiency of the reaction.Benzyltriethylammonium chloride used as phase transfer catalyst could highly enhance the effect of functionalization.Elemental analysis was used to evaluate the degree of functionalization.Characterization was performed using scanning electron microscopy（SEM）and transmission electron microscopy（TEM）.Fourier transform infrared spectroscopy（FTIR）and energy-dispersive X-ray spectroscopy（EDS）were used to confirm the resulting material.
