Method for improving and modifying surface structure of carbon nanotube

The invention discloses a method for improving and modifying the surface structure of a carbon nano tube, which is used for carrying out discharge treatment on the surface of the carbon nano tube in a high-pressure, oxygen-enriched and water vapor environment so as to improve the surface characteristics of the carbon nano tube. The low-energy-consumption method is adopted, meanwhile, no acid wastewater is discharged, pollution is avoided, the overall graphitization degree of the carbon nano tube is remarkably improved by treating surface defects of the carbon nano tube, the quality of the carbon nano tube is effectively improved, the surface electric conduction and heat conduction efficiency of the carbon nano tube is improved, the surface graphitization degree is improved, and meanwhile, the carbon nano tube can be recycled. And the whole free-running property and machinability are improved, so that the production, transportation and management are quicker and simpler. 本发明公开了一种改善和修饰碳纳米管表面结构的方法，在高压、富氧和水蒸气环境下对
