[0057]Example
[0058]Polyurethane PU is used to prepare the electrospinning precursor solution. The solvent is mixed and stirred with 5g dimethylamide and 5g acetone, and 3g PU powder is dissolved in the above solvent to obtain 30wt% of the electrospinning precursor solution. 5mL of silk precursor solution, after installing the spinning needle, connect it to the syringe pump, set the injection pump liquid rate to 10mL / h, then connect the spinning needle to the positive pole of the high-voltage power supply, and connect the fiber collector to the negative pole of the high-voltage power supply and ground, adjust The distance between the spinning needle and the fiber collector is 15cm, and the output voltage of the high-voltage power supply is set to 10kV. After spinning for one hour, turn off the high-voltage power supply and the syringe pump to obtain the PU film substrate 6;
