Graphene oxide (GO) has a wide range of applications and my country’s R&D enthusiasm is high

Graphene oxide (GO) is an oxide of graphene. It has a layered structure internally and a powdery, flaky or solution-like appearance. It has a large number of oxygen-containing groups on its surface and has polymer affinity and hydrophilicity. As a new carbon material with excellent performance, graphene oxide has broad application prospects in biotechnology, optoelectronic devices, flexible sensors, solar cells and other fields.

There are various methods for preparing graphene oxide, including chemical vapor deposition, chemical redox, crystal epitaxial growth, organic synthesis, Hummers method, Brodie method, etc. The Hummers method refers to using phosphorus pentoxide and potassium persulfate to pre-oxidize graphite, and then through shearing, stirring, peeling and other processes to obtain graphene oxide. This method has the advantages of high safety and simple operation. Graphene is widely used in the production process. As local companies continue to deepen their research, my country’s graphene oxide preparation methods have been further improved and optimized, driving the development of the industry to accelerate.

According to the “2023-2028 China Graphene Oxide (GO) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that graphene oxide has broad application prospects in biotechnology, optoelectronic devices, flexible sensors, solar cells and other fields. In the field of optoelectronic devices, graphene oxide can be used to produce organic thin film transistors, which can increase the thickness of their insulating layers; in the field of flexible sensors, graphene oxide has good moisture-sensitive properties and dispersion, making it an ideal material for flexible sensors; in the field of solar cells, Graphene oxide has the advantages of good conductivity and transparency, and can be used as a hole transport layer in solar cells.

In recent years, my country’s enthusiasm for research and development of graphene oxide has been rising, which has led to the further expansion of its application scope. In 2022, Bai Jing’s team at the Institute of Modern Physics, Chinese Academy of Sciences, prepared a glycine-cross-linked graphene oxide membrane. This product has the characteristics of good stability and resistance to swelling, and is expected to be widely used in the field of uranium extraction from seawater in the future.

The main graphene oxide manufacturers in my country include Daoming Optical Co., Ltd., Qitaihe Baotailong Coal Chemical Co., Ltd., Shanxi Yongdong Chemical Co., Ltd., Guangdong Morui Technology Co., Ltd., etc. Baotailong focuses on the R&D, production and sales of graphene oxide slurry and graphene oxide powder. Currently, the company is increasing its research on the stability of graphene oxide. The company’s production capacity ranks at the forefront of my country’s graphene oxide industry.

Industry analysts said that as a new type of carbon material, graphene oxide has a variety of excellent properties and has broad applications in many high-tech fields. prospect. In recent years, my country has shown high enthusiasm for research and development of graphene oxide, preparation technology has been continuously improved and optimized, and the development of the industry has accelerated. It is expected that in the future, attracted by market prospects, the number of graphene oxide production companies in my country will further grow.
