I tried to prepare CNF via electrospinning. The Taylor cone was seen to have been formed and the spray looked quite good. However, after the spinning process, a powder-like material (which can easily be wiped out by rubbing the surface of the aluminium foil) was deposited instead of fiber mat. I would appreciate all your suggestions please.
Dear Adam,
What is your precursor? Provide more info. about the applied electrospinning solution.
Dear Abdullahi Abbas Adam ,
I think one option you can try is to increase the concentration of the spun solution.
Other options might include lower the feeding rate or increase the applied voltage. However, I think the concentration of your solution is the most important factor.
Best regards,

Dear Adam ,
Electrospray is generally caused by the use of a polymer with a low molecular weight or low polymer concentration.

It is a cellulosic material dissolved in DMF/acetone Nooshin Banitaba
I will increase the concentration and try again Cuong Nguyen Thai
I think the molecular weight is okay. Many researchers have reported on the same material Alireza Shaabani
It could be attributed to a number of
factors.
In this case, I think the most important thing is the precursor and the viscosity of the solution.
Try to optimize each one separately to find out the Influential factor.
sincerely.
Increasing the polymer concertation can solve the mentioned problem.
The solution looks quite viscous. Polymer (3g) + 0. 5ml phytic acid in 16 ml DMF/acetone (1:1) Nooshin Banitaba
