Özet
Özet: Bu çalışmada, nanolif elde etme yöntemlerinden en yaygın yöntem olan elektrolif çekim (electrospinning) yöntemi kullanılarak, poliakrilonitril (PAN) polimeri ile nanolif üretilmiştir. Üretilen nanolifler arasına daha sonraki çalışmalarda adsorpsiyon amaçlı kullanılabileceği düşünülerek nanokil serpilerek nanokil katkılı PAN nanolif yüzey elde edilmiştir. Üretilen nanokil katkılı PAN nanoliflerin, taramalı elektron mikroskobu (SEM) ile nanolif boyutları ve lif morfolojileri incelenerek, yaklaşık 950 nm çaplarında oldukları görülmüştür. FT-IR ile kimyasal yapı aydınlatılmaya çalışılmış ve bileşimindeki fonksiyonel grupların varlığı incelenmiştir. Nanoliflerin yapısında PAN ve nanokile ait piklerin oldukları belirlenmiştir. Termal gravimetrik analiz yöntemi (TGA) kullanılarak nanokil katkılı PAN nanolifler termal olarak karakterize edilmeye çalışılmıştır. Çalışılan sıcaklık aralığında iki aşamalı bozunmanın gerçekleştiği ve termal bozunmanın tamamlanmadığı görülmüştür. Nanokil katkılı PAN nanoliflerinden sentezlenen yüzeyin, alternatif bir adsorban madde olarak kullanılabileceği tespit edilmiştir.

Synthesis and Characterization of PAN Nanofiber Added Nanoclay Abstract: In this study, nanofibers have been prepared from polyacrylonitril (PAN) polymer by using electrospinnig method which is the most common method to obtain nanofibers. Nanoclay doped PAN nanofiber webs were prepared by sprinkled nanoclay in spinning process of nanofibers which may be used to purpose of adsorption in other study. Diameter sizes and morphology of the produced PAN nanofibers including nanoclay were examined through SEM and it was observed that nanofibers have about 950 nm diameters. The chemical structure has been tried to be illuminated by using FT-IR and the presence of functional groups in this composition have been investigated. It was observed that there were peak belonging to PAN and nanoclay within the structure of nanofibers. PAN nanofibers included nanoclay have been tried to be characterized thermally by using the TGA (thermal gravimetric analysis) method. In the studied range of temperature, it was observed that two-stage degradation occurred and the thermal degradation was not completed. It was determined that the PAN nanofibers were electrospun with nanoclay could be used as a new alternative adsorbent. Key words: Nanofibers, nanoclay, PAN(Polyacrylonitrile), electrospinning, SEM.

The chemical structure has been tried to be illuminated by using FT-IR and the presence of functional groups in this composition have been investigated. It was observed that there were peakbelonging to PAN and nanoclay within the structure of nanofibers.
