Embodiment 8
[0032] Embodiment 8: In order to further verify the method proposed by the present invention, the ionic liquid was replaced with 1-allyl-3-vinylimidazolium bromide ionic liquid, and its molecular structure is as follows.
[0033]
[0034]Add 1-allyl-3-vinylimidazole bromide ionic liquid into dimethyl sulfoxide (DMSO) according to the ratio of (ionic liquid weight / PVDF weight) = 0.2, 0.3, 0.4, 0.6, fully dissolve and pour Put it into the weighed polyvinylidene fluoride, mix thoroughly with a glass rod, then place it in a constant temperature water bath at 60°C, and stir it with an electric stirrer for 1 hour until it is fully dissolved and a uniform transparent solution is obtained. After dissolving, if there are many bubbles in the solution, it can be placed in a dry box for a while to eliminate bubbles. If there are no bubbles or few bubbles, this step can be omitted. After removing the air bubbles, pour the film-casting solution on a clean glass plate and scrape it into a...
