What is the effect of the addition of salt to the polymer solution on the diameter and beads formation of nanofibers?
Dear Drsalih Habeeb
Addition of salt will increase the conductivity of the solution as the result we have an impact of fiber size reduction during electrospinning process.
Likely a slight improvement in dispersion since you neutralize the negative surface of your cellulose.
The added salt will increase the conductivity of the solution. If the process is electrospinning then higher solution conductivity will reduce average fiber diameter (considering the fact that other parameters are exactly similar). At higher conductivity beads are supposed to be absent.
However, if the conductivity is too high then there is a chance of unstable jet and fibers with wide range of diameters. So it's important to keep the conductivity up to a level. All these things depend on which polymer you are using, the concentration you need, molecular weight of the polymer.
Please specify first, what is your process (electrospinning or others…), what is your polymer and what type of salt ( chemistry talking : mono di valent...). Your salt concentration is also a parameter.
So giving you an answer without all these information will quite approximative. Regards
