Embodiment 1
[0018] In the present embodiment, the amide complexing agent polyvinylpyrrolidone (PVP) is selected, and the specific processing steps are as follows:
[0019] The first step: use low-cost, common-quality PVA as raw material, the solvent is deionized water, the PVA content is 7% (w / v), stir at a temperature of 70°C, and wait for the PVA to fully dissolve to obtain a uniform solution.
[0020] The second step: adding PVP (K30) with a mass ratio of 60% to the PVA in the dissolved PVA solution, continuing to stir, and completing the complexation reaction after dissolving.
[0021] Step 3: inject the above solution into the spinning solution container of the electrospinning machine, the spinning temperature is room temperature, the output voltage of the high voltage power supply is 17KV, and the distance between the receiving screen and the spinneret is 16cm. The electrospinning process is stable, the solution hangs in the shape of droplets at the tip of the gun and forms a Taylor...
