Effect of LiCl on electrospinning of PAN polymer solution: theoretical analysis and experimental verification

Polyacrylonitrile(PAN) is used to study the effect of surface charge on electrospinning by adding LiCl. The theoretical analysis shows that the relationship between radius r of jet and the axial distance z from nozzle follows an allometric law in the form r∼ z −0.5 in case of full surface charge, an...

Zusammenfassung:Polyacrylonitrile(PAN) is used to study the effect of surface charge on electrospinning by adding LiCl. The theoretical analysis shows that the relationship between radius r of jet and the axial distance z from nozzle follows an allometric law in the form r∼ z −0.5 in case of full surface charge, and the scaling exponent becomes larger for partly charged fibers in electrospinning.
