氨基改性氧化石墨烯及其与环氧树脂的复合
Aminofunctional Modification of Graphene Oxide Sheets and Its Composite with Epoxy Resin
摘要
Abstract
Research on aminofunctional modification of graphene oxide sheets and its composite with epoxy resin was carried out. Using flake graphite as a raw material, graphite oxide was prepared by Hummers method, and obtained graphene oxide sheets by ultrasonic process. Triethylenetetramine and ethylenediamine was introduced to the surface of graphene oxide sheets by shrink mixture method, and then epoxy/aminofunctional modified graphene oxide sheets composite was prepared. The characterization with XRD, TGA, FTIR, Raman, and SEM showed the partial reduction of graphene oxide sheets after the aminofunctional modification. Besides, the introduction of modified graphene oxide sheets into epoxy composite increased the elastic modulus and tensile strength of composite by 100 % and 60 %, respectively.关键词
