Hi,

You can use 70,000 g-mol Mw PVA (>90% hydrolized).

Somaya A.Amer

Dear, use high molecular weight especially if you will use aqueous solution PVA.

Mehdihasan Shekh

In electrospinning, M.W. can play an important role. If M.W. is low (35, ooo) are easily spun into nanofobers at lower applied voltage(5-8kV).

So, you have to use the PVA which have more than 40,000 M.W and water used as solvent.
