14% PAN spinning solutions；
（3）At ambient temperature, distance 15cm, 15~18kV of voltage, 0.5 milliliter of flow velocity are received per hour, after continuous electro-spinning 4h
It is standby that PAN fiber film is put into 70 DEG C of oven drying 12h of people；
（4）PAN fiber film is cut into 2 cm x 4cm are rectangular-shaped to be put into Noah's ark；
（5）In air atmosphere, first pre-oxidized in tube furnace, then in a nitrogen atmosphere, rise to respectively 700 DEG C-
1100 DEG C are carbonized；
（6）Pre oxidation is warming up to 3 centigrade per minutes, is incubated 1h；Then boiler tube is vacuumized, is passed through nitrogen, maintained
Stable nitrogen atmosphere, it is warming up to 700 DEG C -1100 DEG C respectively from Pre oxidation with 6 centigrade per minutes, is incubated 0.5h；Most
After naturally cool to room temperature after produce.
Preferably, the step（5）Temperature be carbonized for 70 degrees Celsius.
Preferably, the nitrogen is warming up to 1100 DEG C from Pre oxidation respectively with 6 centigrade per minutes.
Nano fibrous membrane prepared by the method for the invention, carbonized film surface is smooth, zero defect, with the liter of carburizing temperature
Height, filamentary structure become finer and close and ordering, and graphite layers are away from reduction.
