Abstract

Coaxial electrospinning, which is a modified electrospinning technique involving an arrangement of multiple solutionfeed systems, enable the production of multilayered nanofibers. In this study, multilayered nanofibers of polyamide 6 (core) /polycaprolactone (shell) containing silver nanoparticles in the core were produced by coaxial electrospinning method. UV-Visiblespectra showed that the size of nanoparticles were about 10 nm and the content of nanoparticles were observed to be proportional to theprecursor content added to the solvent. The obtained multilayered nanofibers were characterized in terms of morphology, chemicalstructure, and silver release properties. The multilayered nanofiber structure was confirmed by the selective dissolution and removal ofshell layer. The increase in the PCL content of the multilayered nanofibers with the increase in the flow rate of the shell solution wasconfirmed by FTIR. The silver release profiles of the nanofibers were observed to be dependent on the nanofiber configuration, andsilver content. Shell thickness was also an important parameter affecting the silver release properties for multilayered nanofibers.

Özet

Konvansiyonel elektro lif çekim yönteminin birden çok çözeltinin beslenmesine yönelik yapılan modifikasyonu ile elde edilen koaksiyal elektro lif çekim yöntemi, çok katmanlı nanoliflerin üretimini sağlayan bir yöntemdir. Bu çalışmada, koaksiyal elektro lif çekim tekniği kullanılarak öz kısmında gümüş nanopartiküller içeren polyamide 6 (öz) / polikaprolakton (kabuk) nanolifler üretilmiş ve elde edilen çok katmanlı nanolifler morfoloji, kimyasal yapı ve gümüş salım özellikleri açısından değerlendirilmiştir. UV-görünür bölge spektroskopisi, sentezlenen gümüş nanopartiküllerin 10 nm’den küçük olduğunu ve gümüş nanopartikül miktarının, çözeltiye eklenen prekursör miktarı ile orantılı olduğunu göstermiştir. PCL kabuk kısmının çözülerek uzaklaştırılması ve PA6 öz kısmının geride saf halde, nanolif formunda kalması ile koaksiyal nanolif yapısı doğrulanmıştır. Kabuk çözeltisinin besleme hızı arttırıldığında, nanolif yapısındaki PCL miktarı artmış ve FTIR spektrumunda PCL’e ait piklerin şiddetleri artmıştır. Nanoliflerin gümüş salım profillerinin nanolif konfigürasyonu, gümüş prekursör miktarı ve çok katmanlı nanoliflerde ayrıca kabuk kalınlığına bağlı olarak değiştiği görülmüştür.
