Embodiment 1
[0032] The purchased white pure cotton cotton cloth is treated as follows: ultrasonically wash with deionized water for 15 minutes, then ultrasonically wash with ethanol for 15 minutes, and ultrasonically wash with acetone for 5 minutes, take it out and dry it in an oven at 80°C for 3.5 hours .
[0033] The azophenylmaleimide and the solvent are formulated into a polymer solution according to the ratio of 1g:55g, and the solvent is dimethyl sulfoxide.
[0034] Single-axis electrospinning equipment is used for spinning, and the electrospinning device is composed of a high-voltage power supply, an extrusion injection device and a receiving device. The spinning solution was filled into a syringe with a volume of 2.5 mL, and the inner diameter of the syringe needle was 0.24 mm. Connect the positive pole of the high-voltage power supply to the needle, and the receiving board to the ground. The spinning voltage is 16kV, the flow rate of the spinning solution is 0.11mL / h, the recei...
Embodiment 2
[0037] The purchased white pure cotton cloth is treated as follows: ultrasonically wash with deionized water for 20 minutes, then ultrasonically wash with countless ethanol for 10 minutes, ultrasonically wash with acetone for 20 minutes, take it out and dry it in an oven at 60°C for 6 hours .
[0038] The azophenylmaleimide and the solvent are formulated into a polymer solution at the ratio of 1g:100g, and the solvent is chloroform.
[0039] The spinning solution was filled into a syringe with a volume of 2.5 mL, and the inner diameter of the syringe needle was 0.24 mm. Connect the positive pole of the high-voltage power supply to the needle, and the receiving board to the ground. The spinning voltage is 18kV, the flow rate of the spinning solution is 0.1mL / h, the receiving distance is 18cm, and the relative humidity in the room is 28%.
