摘要： A method for preparing a carbon nanotube, including: a) preparing an LPAN solution, stirring the LPAN solution at between 100 and 200° C. for between 100 and 200 hours to yield a cyclized LPAN solution; b) heating the cyclized LPAN solution at between 200 and 300° C. for between 1 and 10 hours to yield an OPAN; c) grinding, screening, and drying at room temperature the OPAN to yield a thermal oxidative precursor; d) calcining the thermal oxidative precursor at between 400 and 1000° C. for between 1 and 24 h in the presence of inert gas having a flow rate of between 10 and 500 mL/min to yield a carbonated precursor; and e) calcining the carbonated precursor at between 1000 and 1500° C. for between 1 and 10 hours in the presence of the inert gas having a flow rate of between 10 and 500 mL/min to yield a carbon nanotube material.
