Evaluation of waste human hair as graphene oxide and examination of some characteristics properties

Öz

In this study, graphene oxide was synthesized from activated carbon obtained from waste hair for the first time using Modified Hummers method. the Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), Raman Spectroscopy and X-Ray Diffraction (XRD) analysis results of synthesized graphene oxide were examined. In SEM images, graphene oxide structures were observed as very thin layers. In addition, the characteristic peaks of graphene oxide were observed in FT-IR spectroscopy and Raman spectroscopy. In the XRD spectra, reflections of the graphene oxide were seen in plane (001) at 2θ=13.66. It was determined that this structure was hexagonal crystal structure. The distance d (6.39Å) between the planes and the weave parameters were determined to be 12.80 Å. The transformation process for actived carbon production from human hair waste was patented by Turkish Patent and Trademark Office (Turkish Patent Institute Application Number: (2017/10764).

Öz

Son zamanlarda, üstün elektriksel, mekanik, termal ve optik özelliklere sahip nanomalzeme , grafen önemli bir araştırma konusu haline gelmiştir. Bu çalışmada, modifiye Hummers yöntemi kullanılarak ilk kez atık saçtan elde edilen aktif karbondan grafen oksit sentezlendi. Sentezlenen grafen oksitin Taramalı Elektron Mikroskobu (SEM), Fourier Dönüşüm Kızılötesi (FT-IR) Spektroskopisi, Raman Spektroskopisi ve X Işını Kırınım (XRD) analiz sonuçları incelendi. SEM görüntülerinde katmanlı ve çok ince tabakalar halinde grafen oksit yapıları gözlendi. Ayrıca, FT-IR spektroskopisi ve Raman spektroskopisinde ise grafen oksite ait karakteristik pikler görüldü. XRD spektrumda grafen oksite ait 2θ = 13.66 °de (0.01) düzleminde yansımalar görüldü. Oluşan bu yapının hekzagonal kristal yapıda olduğu belirlendi. Düzlemler arasındaki d mesafesi (6.39) ve örgü parametreleri 12.80 Å olarak belirlendi. İnsan saçı atıklarından aktif karbon üretimi dönüşüm süreci, Türkiye Patent ve Marka Ofisi tarafından patentlendi (Türkiye Patent Enstitüsü Başvuru Numarası: (2017/10764).
