Elektro Eğirme Yöntemiyle ZnO Nanofiberlerin Üretilmesi ve Karakterizasyonu

Bu çalışmada 1D ZnO nanofiberleri, çinko asetat ve polivinil alkol (PVA) öncü çözeltisinden elektro eğirme tekniği kullanılarak sentezlenmiş ve ardından atmosfer ortamında 400°C'de 2 saat kalsinasyon yapılmıştır. Elektron mikroskop analizleri (SEM) tavlama sonrasında nanofiber yapıların pürüzlü yüzeyini, EDX analizleri ise Zn: O atomik oranın 1:1 olduğunu ve safsızlığını göstermiştir. XRD karakterizasyonu polikristalin yapıyı ortaya koymuş ve RAMAN spektrumu optik fonon modlara işaret etmiştir. FTIR ile ZnO fonksiyonel grup analizleri belirlenmiştir.

Fabrication and Characterization of ZnO nanofibers by Electrospinning Technique

In this study, 1D ZnO nanofibers were synthesized from zinc acetate and polyvinyl alcohol (PVA) precursor solution using electrospinning technique, and then calcined in air environment at 400°C for 2 hours. Electron microscope analyzes (SEM) showed the rough surface of the nanofiber structures after annealing, and EDX analyzes demonstrated that the Zn:O atomic ratio was 1:1 and impurity. XRD characterization revealed the polycrystalline structure and the RAMAN spectrum indicated optical phonon modes. ZnO functional group analyzes were determined by FTIR.
