Embodiment 1
[0026] First add 10wt% LiCl to the N,N-dimethylformamide solution, then add polyvinylidene fluoride powder evenly, control the concentration at 15%, and add a magnetic rotor at the same time, in an oil bath with magnetic stirring Stir at a speed of 90r / min and 50°C for 60min, the powder is completely dissolved to obtain a clear viscous solution, which is the electrospinning solution of polyvinylidene fluoride, and a yellow gel-like solid is obtained after standing for 5 days. The obtained solid was put on a clean Erlenmeyer flask, and then the Erlenmeyer flask was put into a hot air drying oven with a temperature set at 150° C. for heat treatment for 12 hours. Take out the Erlenmeyer flask, put it into a desiccator to cool at room temperature for 30 minutes, then pour the melted polyvinylidene fluoride electrospinning solution into a clean Erlenmeyer flask, and store it for later use.

Embodiment 2
[0029] Add 8% LiCl to the N,N-dimethylacetamide solution, then slowly and evenly add polyvinylidene fluoride powder with a concentration of 10%, in an oil bath with magnetic stirring at a speed of 120r / min and Stir at 45°C for 90 minutes until the powder is completely dissolved, and a clear viscous solution is obtained, which is the electrospinning solution of polyvinylidene fluoride. After standing for 3 days, a white gel-like solid is obtained. The obtained solid was put into a clean Erlenmeyer flask, and then the Erlenmeyer flask was put into an oil bath set at 125° C. for heat treatment for 15 hours. Take out the Erlenmeyer flask, put it into a desiccator to cool at room temperature for 30 minutes, then pour the melted polyvinylidene fluoride electrospinning solution into a clean Erlenmeyer flask, and store it for future use.

Embodiment 3
[0032] First add 9% LiCl to the N-methylpyrrolidone solution, then slowly and evenly add polyvinylidene fluoride powder, the concentration is controlled at 20%, while controlling the temperature at 40°C and the speed of 105r / min under temperature-controlled magnetic stirring Stir the mixture in a container for 120 minutes, the powder is completely dissolved, and a clear viscous solution is obtained, which is the electrospinning solution of polyvinylidene fluoride, and the solution is left to stand for 7 days to obtain a colorless gel-like solid. The obtained solid was put into a clean Erlenmeyer flask, and then the Erlenmeyer flask was put into a hot air drying oven with a temperature set at 105° C. for heat treatment for 18 hours. Take out the Erlenmeyer flask, put it into a desiccator to cool at room temperature for 30 minutes, then pour the melted polyvinylidene fluoride electrospinning solution into a clean Erlenmeyer flask, and store it for future use.
