Bu çalışmada; silindirli elektro lif çekimi ile polivinil alkol (PVA) nano lif üretiminde, glioksal çapraz bağlayıcı ve sodyum klorit (NaCl) tuz ilavesinin çözelti özellikleri (iletkenlik, yüzey gerilimi, viskozite), lif çekim performansı ve lif özellikleri (çap ve çap üniformitesi) üzerindeki etkileri tartışılmaktadır. Elde edilen sonuçlara göre; glioksal çapraz bağlayıcı ve NaCl tuz ilavesi ile çözelti iletkenliği, viskozite ve lif çapı artmaktadır. Diğer yandan, PVA lif çekim performansı çapraz bağlama işlemi ile artmakta, fakat NaCl tuz konsantrasyonu artışı ile azalmaktadır. Buna ilaveten; NaCl tuz konsantrasyonu ile lif çapı üniformitesi arasında herhangi bir ilişki bulunmamaktadır. Genel olarak, silindirli elektro lif çekim yöntemi ile yüksek lif yoğunluğu, ince ve homojen PVA nano lifler elde edilmiştir

THE EFFECT OF GLYOXAL CROSS-LINKER AND NaCl SALT ADDITION ON THE ROLLER ELECTROSPINNING OF POLY(VINYL ALCOHOL) NANOFIBERS

Öz

In this study, the effects of the addition of glyoxal cross-linker and sodium chloride (NaCl) salt on the solution properties (conductivity, surface tension, viscosity), spinning performance and fiber properties (diameter and diameter uniformity) in roller electrospinning of poly(vinyl alcohol) (PVA) are discussed. According to the results, solution conductivity, viscosity and fiber diameter increase with the addition of glyoxal cross-linker and NaCl salt. On the other hand, the spinning performance of PVA increases with cross-linking treatment, but decreases as the NaCl salt concentration increases. In addition, there is no relation between NaCl concentration and fiber diameter uniformity. Generally, high fiber density, fine and uniform PVA nanofibers were obtained via the roller electrospinning method
