溶胶凝胶法制备氧化石墨烯/氧化铝复合材料
Preparation of Graphene Oxide/Alumina Composite Materials Through Sol-gel Method
摘要
Abstract
In this work,with aluminium isopropoxide (AlIP) and an aqueous suspension of graphene oxide(GO) as raw materials,composites of graphene oxide and alumina (GO/Al2O3) with different GO to AlIP ratios were prepared by sol-gel method.The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images show that the as-obtained composites have unique structures in which the GO sheets coated by nano-particles.The particles were demonstrated to be alumina by X-rays diffraction (XRD),and the average grain size of the particles was demonstrated about 50 nm by atomic force microscope (AFM).The growth mechanism of the composites was proved.First of all GO combined with AlIP molecules,and then AlIP hydrolyzed into small AlOOH particles on the surfaces of GO plates.As the reaction proceeding,particles gradually grew up.Eventually through the high temperature treatment,AlOOH turned into Al2O3.关键词
