    Thank you very much for the video but you can not tell they are nanofibers until you have an SEM image. We had some experiments with PVA recently. Everything looked ok during the process. However, when we looked at the SEM images there were no fibers. Just some PVA drops on the foil.

      increase the viscosity of the solution

    Hi, what % of concentrations did you use? And for how much time did you perform the electrospinning? I find it hard to maintain a stable taylor cone, and also to obtain a right amount of materials that can be removed from aluminum foil and be analised, do you have any tips?

    I read somewhere that homogenizer might break the PVA chains and change the molecular weight.

    A serious question, these are so delicate how do i remove it from foil and handroll them to coat stuff and do tensile/ conductivity tests?. These are so delicate.

    I did the same using PET 5% solution, but it's difficult to remove it without striching it
