Trial spinning of gelatin/PVP mixed nanofiber sheet②

By changing the solvent that was previously spun and increasing the percentage of gelatin in the solution Gelatin and PVP mixed nanofiber sheets have been newly spun.
When immersed in ethanol, it became gelatinous, but when observed with a microscope, the shape of the nanofiber remained smaller than the previous one.
We will continue to conduct experiments so that gelatin nanofiber sheets can be produced.
If you have any advice, I would be very grateful if you could teach me.
