Embodiment 1
[0050] Step 1: Functional modification of carbon nanotubes
[0051] The following methods are used to modify different functional groups on the surface of carbon nanotubes so that the surface of carbon nanotubes carry different charges and functional group molecules to improve the dispersibility and biocompatibility of carbon nanotubes. The specific methods are as follows:
[0052] (1) Mix the carbon nanotubes with 2.0M sodium hydroxide ultrasonically and reflux for 12 hours, and then centrifuge, filter, clean and dry the carbon nanotubes to obtain high-purity carbon nanotubes with hydroxyl groups on the surface;
[0053] (2) The mixed acid adopts the ratio of sulfuric acid:nitric acid = 3:1, reflux the carbon nanotubes in the mixed acid at 80°C for 30 minutes, repeatedly wash with deionized water to avoid introducing other impurities, and then centrifuge, filter and clean the carbon nanotubes And drying to obtain high-purity carbon nanotubes with carboxyl groups on the surface;
