Fe3O4@HA@Ag nanokompozitlerin hazırlanması, PVP ile nanolif üretimi ve karakterizasyonu

Manyetit (Fe3O4), Hümik Asit (HA) ve Gümüş (Ag) önemli özelliklere sahip malzemelerdir. Bu malzemelerin özelliklerini taşıyacak tek bir malzeme sentezlenmesi ve kullanılması bazı uygulama alanları için önemli ölçüde avantaj sağlayabilecektir. Bu çalışmada, sentezlenen Fe3O4@HA@Ag, %5, %7.5 ve %10 ağırlık oranlarında polivinilpirolidon (PVP) içerisine katkılandırılarak elektrospinning yöntemi ile nanolif üretimi gerçekleştirilmiştir. Üretilen nanolifli yapıların yapısal özellikleri X-ışını Kırınımı (XRD) ile morfolojik özellikleri Taramalı Elektron Mikroskobu (SEM) ile spektroskopik ve termal karakterizasyonları da Fourier dönüşümü kızılötesi (FTIR) ve Termogravimetrik Analiz (TGA) ile incelenmiştir. Nanoliflere ait analiz sonuçları değerlendirildiğinde, Fe3O4@HA@Ag katkılı PVP nanoliflerin başarılı bir şekilde üretildiği tespit edilmiştir.

Preparation of Fe3O4@HA@Ag nanocomposites, production of nanofiber with PVP and its characterization

Magnetite (Fe3O4), Humic Acid (HA) and Silver (Ag) are materials with important properties. Synthesizing a single material which will have all the properties of these materials can provide significant advantages for some application areas. In this study, synthesized Fe3O4@HA@Ag was doped into poly(vinyl pyrrolidone) (PVP), in weight ratios of 5%, 7.5% and 10%, and nanofiber production was carried out by electrospinning method. Structural properties of nanofiber structures were investigated by X-ray Diffraction (XRD), morphological properties by Scanning Electron Microscope (SEM), spectroscopic and thermal characterizations by Fourier transform infrared (FTIR) and Thermogravimetric Analysis (TGA). When the analysis results of nanofibers were evaluated, it was determined that Fe3O4@HA@Ag doped PVP nanofibers were successfully produced.
