Analyis of Morphological Characteristics of Polyamide 6/Chitosan Blended Nanofibers Fabricated by Electrospinning

Abstract

In our study, various ratios of Polyamide 6 and Chitosan blended nanofibers in the nanofibrous composite form obtained via electrospinning at ambient atmosphere. Homogenous Chitosan solutions were prepared in aqeous acetic acid. Polyamide 6 was dissolved in formic acid. Properties of all blended solutions were determined by measuring viscosity, conductivity and pH values. It was recorded that when the Chitosan content increased in the blend solution, viscosity was also increased, however, conductivity was decreased. SEM analysis was conducted to investigate the characteristics of the final nanofibrous composite structures. Beadless and uniform nanofibers were obtained and the diameter of the fibers ranged from 87±22nm to 44±26nm

Elektroçekim Yöntemiyle Elde Edilen Poliamid 6/Kitosan Bazlı Nanoliflerin Morfolojik Özelliklerinin İncelenmesi

Abstract

Çalışmamızda, elektroçekim yöntemiyle çeşitli karışım oranlarında Poliamid 6 ve Kitosan içeren nanolif bazlı kompozit yapılar elde edilmiştir. Kitosan, asetik asit ile Poliamid 6 ise formik asit yardımıyla çözülmüştür. Çözeltilere ait özellikler, viskozite, iletkenlik ve pH ölçümleri ile saptanmıştır. Karışımdaki Kitosan miktarı arttıkça, iletkenliğin azaldığı, viskozitenin ise arttığı kaydedilmiştir. Nanolif bazlı kompozit yapıların morfolojik özellikleri SEM analizleri ile tespit edilmiştir. Elektroçekim işlemi sonucu düzgün ve hatasız lifler elde edilmiştir. Lif incelikleri 87±22nm ve 44±26nm aralığında değişim göstermiştir
