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

آقا عالی ، خسته نباشید
Can you plz tell me the ingredients ?
@@muqaddasshakeel779 it's pva polymer (Polyvinyl alcohol) that turn into nano form

Excellent, thanks 🌹

I did the same using PET 5% solution, but it's difficult to remove it without striching it
can we use it for annulus fibrosis repair in herniated disc?

i have a question why did u use 2.5 gram of polymer if your concentration was 8%? can u tell me how did u prepare ur solution please
