Fabrication and Characterization of GNP doped Hybrid PVB-TEOS Nanofibers

Abstract

PVB/TEOS and PVB/TEOS/GNP (Graphene Nanoplatelet) nanofibers have been synthesized via electrospinning method and exhibit a homogeneous and bead-free morphology. Polyvinyl butyral (PVB) was used as precursor polymer that allows the silica-based nanofiber to diminish of flaws. The average diameter of PVB/TEOS (Tetraethyl orthosilicate) nanofiber ranged from 150 to 500 nm. Structures and morphologies of the PVB/TEOS and PVB/TEOS /GNP nanofibers were examined by Thermogravimetric Analyzer (TGA), Fourier Transform Infrared spectrometer (FTIR) and Scanning Electron Microscopy (SEM). The results demonstrate that the obtained nanofibers can be used as nanomaterials for a wide variety of applications such as tissue engineering, drug delivery, cancer diagnosis, battery, sensors and air filter.

GNP katkılı Hibrit PVB-TEOS Nanofiberlerin Üretimi ve Karakterizasyonu

Öz

Polivinil bütral (PVB)/Tetraetil ortosilikat (TEOS) ve PVB/TEOS/ Grafen nanoplatelet (GNP) nanofiberler elektro eğirme yöntemi ile sentezlenmiş ve homojen, boncuksuz bir morfoloji sergilemiştir. PVB, silika bazlı nanofiberler içerisindeki kusurların azalmasını sağlayan öncü polimer olarak kullanılmıştır. PVB/TEOS nanofiberlerin çapları 150-500 nm arasında değişmektedir. PVB/TEOS ve PVB/TEOS/GNP nanofiberlerin yapıları ve morfolojileri termogravimetrik analizör (TGA), Fourier dönüşümlü kızılötesi spektrometresi (FTIR) ve taramalı elektron mikroskobu (SEM) analizleri ile incelenmiştir. Analizler, elde edilen nanofiberlerin doku mühendisliği, ilaç salınımı, kanser teşhisi, batarya, sensör ve hava filtresi gibi uygulamalarda nanomalzeme olarak kullanılabileceğini göstermektedir.
