The effect of polymer and salt concentration on fiber properties in electrospinning of polyurethane nanofibers [Elektro lif çekim yöntemi ile poliüretan nano lif üretiminde polimer ve tuz konsantrasyonunun lif özelliklerine etkisi]

In this study,effects of polyurethane (pu) polymer concentration and tetraethylammoniumbromide (teab) salt concentration on the nanofiber properties (such as fiber diameter,diameter uniformity,non-fibrous area,amount of bead),which was produced by needle electrospinning method,were investigated. it was determined from the results,that spinnability increases therefore non-fibrous area decreases as the pu polymer concentration increases. also it was observed that fiber diameter increases and number of beads on nanofibrous structure decreases prominently with pu and teab concentration. on the other hand it was found that there was no relationship between the fiber diameter uniformity coefficient and pu and teab concentrations.
