Niu Li, a researcher at the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, carried out a series of research work on the theoretical design, preparation, synthesis, and characterization of two-dimensional graphene materials and their applications in the field of electroanalytical chemistry. Graphene sheets, thin films and Graphene hybrid materials, and further explore the chemical structure characteristics and reaction mechanism of graphene and its hybrid materials, apply graphene and its hybrid materials in the field of sensing analysis, composite materials and energy environment, and achieved a series of important Research progress. Recently, this achievement won the first prize of 2015 Jilin Provincial Natural Science Award.
Graphene is a carbonaceous new material with carbon atoms tightly packed into a single-layered two-dimensional honeycomb structure. Due to its excellent electrical, mechanical, thermal and optical properties, graphene can be widely used in aerospace, medical inspection, food safety, and energy. Environmental, electronic information, chemical sensing and other fields.
Researchers at Changchun Institute of Chemical Technology have taken the lead in proposing microwave-assisted oxidative intercalation and stripping for problems such as low yields, many defects, and poor controllability in conventional oxidized stripping methods. The method is low in cost, has good processability, and is easy to scale up. It is easy to mass-produce graphene materials with high conductivity and high transmittance; for the first time in the world, electrochemical reduction of graphene oxides is used to prepare two-dimensional single-layer graphene films, which can form any size on conductive and non-conductive substrates. The different patterns, and the preparation is simple and effective, especially in the soft plastic film, has a good application prospects; the use of water / oil two-phase interface self growth method to achieve complete transfer of graphene nano-sheet layer to the interface The film can be quickly transferred to various substrates, and the prepared graphene nanofilm shows adjustable optical transparency and conductivity, as well as highly reversible light-induced conversion, these characteristics are future graphene in the field of nanodevices The foundation of the application; the use of physical adsorption, chemical grafting, and physical/chemical composite modification methods for the graphene material Derivatization and modification, development of chitosan, azo dyes, ionic liquids, silanes, ferrocene, polyvinylpyrrolidone, phospholipid monolayers, polylysine, polyethyleneimine, metal nanomaterials, photocatalytic activity Various graphenes and their hybrid materials with special properties were studied in detail. The chemical structure characteristics of these materials were studied in detail, and the reaction mechanism was preliminary explored. The new graphene and its hybrid materials were modified to lead in electrode interface modification. , Analyze the application of sensors and energy fields.
