[0013] The present invention also provides a method for preparing a carbon nanotube / nylon 6 composite material. The steps include: preparing modified carbon nanotubes; mixing the modified carbon nanotubes with nylon 6 to prepare a slurry, and then extruding to obtain carbon Nanotube / nylon 6 composite material.
[0014] Preferably, preparing the modified carbon nanotubes includes subjecting the carbon nanotubes to acid washing or hydrogen peroxide washing, and then to dispersing agent treatment.
[0015] Preferably, the acid washing or hydrogen peroxide washing includes immersing the carbon nanotubes in an acidic solution or hydrogen peroxide for 1-24 hours at 50-80°C; wherein the acidic solution is selected from concentrated H with a volume concentration of 25%-75% 2 SO 4 , Concentrated HNO with a volume concentration of 25%-75% 3 And a kind of aqua regia with a volume concentration of 25%-75%. The aqua regia includes concentrated HCL with a volume concentration of 25%-37.5% and co...
