Analisa Pengaruh Reduksi Termal Terhadap Kerusakan Struktur (Structural-Disorder) Pada Lapisan Tipis Graphene Oxide Tereduksi

Abstract: Tujuan penelitian ini adalah menganalisa kerusakan struktur pada lapisan tipis graphene oxide setelah direduksi pada temperatur reduksi yang bervariasi. Lapisan tipis graphene oxide yang disintesis menggunakan metode Hummers direduksi secara termal pada variasi temperatur 350 0 C dan 850 0 C selama 2 jam dalam pemanas vakum (~10-3 Torr). Kuantitas defect sampel dikarakterisasi menggunakan Raman Spectroscopy sedangkan mikrostrukturnya dikarakterisasi menggunakan SEM (Scanning Electron Microscope). Persentase (k… Show more

“…Thermal reduction at high temperature up to 8000 o C will decompose and introduce the formation of structural defect on graphene sheets [23]. Chemical reduction was also carried out using hydrazine/hydrazine derivatives which are unstable and toxic reducing agents [24]. Therefore, expoloration of various enviromentally friendly reducing agents such as ascorbic acid [25], bacterial respiration [26], anticoagulant [27] including the use of natural resources such as carrot root [28], and grape extract [29].…”
