Abstract

Graphene oxide syntheses obtained by bringing a new approach to Hummers method, scanning and transmission electron microscopy analyzes were examined and it was examined whether they fit other graphene oxide syntheses in the literature. From SEM analysis; , it was observed that oxygen-containing functional groups covalently bond with carbon atoms in the basal plane of graphite and deconstruct the sp2 conjugate system, so the morphology of a nano-surface with wavy, folded regions, thin and flexible layers prevails, and the inter-layer gaps are wider than in graphite.. From TEM analysis; it was observed that it exhibits an ultra-thin silky appearance and its edges have a folded veil-shaped morphology, dark and translucent areas appear under the electron beam. It has been determined that these results were compatible with the graphene oxide syntheses in the literature.

Özet

Hummers yöntemine yeni bir yaklaşım getirerek elde edilen grafen oksite sentezlerinin, taramalı ve geçirimli elektron mikroskopu analizleri incelenered literatürdeki diğer grafen oksit sentezlerine uyup uymadıkları incelenmiştir. SEM analizlerinden; oksijen içeren fonksiyonel grupların, grafit bazal düzleminde karbon atomları ile kovalent olarak bağlanıp sp2 konjuge sistemini bozduğunu dolayısıyla dalgalı, katlanmış bölgeli, ince ve esnek tabakalı bir nano yüzey morfolojisinin hakim olduğu, tabakalar arası boşlukların grafite göre daha geniş olduğu gözlenmiştir. TEM analizlerinden; ultra ince bir ipeksi görünüm sergilediği ve kenarlarının katlanmış peçe şeklinde bir morfolojiye sahip olduğu, elektron ışını altında karanlık ve yarı saydam alanlar ortaya çıktığı gözlenmiştir. Bu sonuçların da literatürdeki grafen oksit sentezlerine uyum sağladıkları belirlenmiştir.
