PAN/Zeolit Esaslı Nanoliflerin Üretimi ve Karakterizasyonu

Abstract

Bu çalışmada, poliakrilonitril (PAN)/zeolit nanoliflerin elektro lif çekim yöntemi ile üretimi ve karakterizasyonunun gerçekleştirilmesi amaçlanmıştır. İlk olarak, farklı zeolit konsantrasyonlarında polimer çözeltileri hazırlanmıştır. Daha sonra, viskozite, iletkenlik ve yüzey gerilimi gibi çözelti özellikleri belirlenmiştir. Nanolif üretimi optimum proses parametreleri (voltaj, elektrotlar arası mesafe, besleme hızı ve atmosferik koşullar) altında elektro lif çekim yöntemi ile gerçekleştirilmiştir. Son olarak, nanolifler SEM-EDS ile morfolojik olarak karakterize edilmiştir. Sonuçlara göre; zeolit konsantrasyonu artışı ile iletkenlik azalırken çözelti viskozitesi ve yüzey gerilimi artmıştır. Ayrıca, lif çekim prosesi boyunca, zeolit konsantrasyonu artışı ile lif çekim performansının azaldığı ve ortalama lif çapının özellikle %10 PAN/%10 zeolit için önemli ölçüde arttığı gözlemlenmiştir. Dahası, zeolit partikülleri maksimum ve minimum konsantrasyonda bile nanolifli yapıya başarıyla tutunmuşlardır.

Production and Characterization of PAN/Zeolite Based Nanofibers

Abstract

In this study, it was aimed to achieve production and characterization of polyacrylonitrile (PAN)/zeolite nanofibers via electrospinning method. Firstly, polymer solutions were prepared with various concentrations of zeolite. Then, solution properties were determined such as; viscosity, conductivity and surface tension. Nanofiber production was carried out with electrospinning under the optimum process parameters (voltage, distance between the electrodes, feed rate and atmospheric conditions). Lastly, nanofibers were morphologically characterized with SEM-EDS. According to the results; solution viscosity and surface tension increased while conductivity decreased with zeolite concentration increasement. Also, during the spinning process, it was observed that spinning performance decreased and average fiber diameter increased dramatically with zeolite concentration especially for 10 wt % PAN/10 wt % zeolite. Moreover, zeolite particles held on to the nanofibrous structure successfully even at minimum and maximum concentration.
