Abstract

Carbon nanotube (CNT) embedded polyacrylonitrile (PAN) nanofibers production by electrospinning
method was reported in this study. Five different CNT concentrations (0.05, 0.1, 0.2, 0.5, and 1wt%)
were tried to obtain beadless and regular PAN/CNT electrospun nanofibers. Scanning Electron
Microscopy (SEM), Raman and X-Ray Diffaraction (XRD) analyses were utilized to characterize
nanofibers. The results indicated that with increasing CNT concentration, the diameter of PAN/CNT
nanofibers increased, and after an optimum concentration some disordered sites and beads were
observed on the nanofibers. However, the addition of CNTs enhanced the graphitization and
crystallinity of PAN nanofibers. The optimum CNT concentration for beadless and high crystalline
PAN/CNT nanofibers was found as 0.1 wt

Karbon Nanotüp (KNT) İlave Edilmiş Poliakrilonitril (PAN) Nanoliflerin Elektroeğirme Yöntemi ile Üretilmesi ve Karakterizasyonu

Abstract

Bu çalışmada elektroeğirme yöntemi ile karbon nanotüp (KNT) ilave edilmiş poliakrilonitril (PAN) nanolif
üretimi rapor edilmiştir. Boncuksuz ve düzenli PAN/KNT elektroeğirme yöntemi ile elde edilmiş
nanofiberler elde etmek için beş farklı KNT konsantrasyonu (0.05, 0.1, 0.2, 0.5 ve %1 ağırlık) denenmiş
ve nanolifleri karakterize etmek için Taramalı Elektron Mikroskobu (SEM), Raman ve X-Işını Difraksiyonu
(XRD) analizleri kullanılmıştır. Sonuçlar, artan KNT konsantrasyonu ile PAN/KNT nanoliflerinin çapının
arttığını ve optimum bir konsantrasyondan sonra nanolifler üzerinde bazı düzensiz bölgeler ve
boncuklanmaların oluştuğunu göstermiştir. Bununla birlikte, KNT'lerin eklenmesi, PAN nanoliflerinin
grafitizasyonunu ve kristalliğini arttırmıştır. Boncuksuz ve kristalizasyon seviyesi yüksek PAN/KNT
nanolifler için optimum KNT konsantrasyonu ağırlıkça %0.1 olarak bulunmuştur.
