Integral device for preparing oxidized graphene and preparation method of oxidized graphene

Abstract

The invention relates to an integral device for preparing oxidized graphene and a preparation method of the oxidized graphene. A jacket reactor of the integral device is arranged on a magnetic stirrer, and an ultrasonic signal generator is arranged on the upper portion of the jacket reactor; an inlet tube and an outlet tube are arranged on the outer jacket of the jacket reactor, a low-temperature cooling water circulation system and a circulating oil bath system are respectively connected to the inlet tube through corresponding outlet pipelines, a cooling water outlet switching valve is arranged on the outlet pipeline of the low-temperature cooling water circulation system, and a heating-oil outlet switching valve is arranged on the outlet pipeline of the circulating oil bath system; the low-temperature cooling water circulation system and the circulating oil bath system are respectively connected to the outlet tube through corresponding inlet pipelines, a backwater switching valve is arranged on the backwater pipeline of the low-temperature cooling water circulation system, and an oil return switching valve is arranged on the oil return pipeline of the circulating oil bath system. By the arrangement that ultrasound performing, stirring and oxidizing processes are performed in one reactor, repeated replacement of experimental equipment is not needed, and semi-automatic operation is realized.

Description

technical field [0001] The invention relates to the technical field of preparation methods for new materials, in particular to an integrated device for preparing graphene oxide and a preparation method thereof. Background technique [0002] In 2004, Andre K. Geim and Konstantin Novoselov, scientists at the University of Manchester in the United Kingdom, successfully prepared single-layer graphene (graphene) using micromechanical exfoliation. , and won the Nobel Prize in Physics in 2010. Since then, graphene has become a hot topic in physics and materials science. With the development of technology, the synthesis methods of graphene oxide are generally divided into Hummers method, Brodie method, and Staudenmaier method. Among them, the Hummers method has a higher degree of oxidation, a higher degree of product regularity, and a higher safety factor, making it the most commonly used method.
