（2）Polyurethane, Polyetherimide mixing, add the DMF that measures of total amount 5-6 times, with 300-400 rev/min of speed stir to
Ludox, nanometer magnesium aluminate are added after being completely dissolved, with ultrasonic disperse after 600-800 rev/min of speed stirring 15-20 minutes
30-40 minutes, obtain modifying agent；
（3）Kynoar, polymethyl methacrylate are mixed at normal temperatures, the DMF for adding total amount 8-9 times to measure, with 400-
Stir under 500 revs/min of speed and add step to after being completely dissolved（1）, step（2）The product for obtaining, continues to stir 120-150
Ultrasonic disperse 40-50 minutes after minute, obtain spinning liquid；
（4）Spinning liquid is carried out into electrostatic spinning, control pushes away liquid speed degree 0.002mm/s, receives apart from 18cm, the condition of voltage 22kv
Lower electrostatic spinning 2 hours, after the completion of spinning, after the fiber membrane collected is dried 12 hours in 60-70 DEG C of vacuum drying oven
Take out, with clean glass is smooth the hot pressing 90-120 minutes at 120 DEG C are pushed down in vacuum drying oven, take out after natural cooling
Obtain final product.
