Global Graphene oxide market trend 2022-2027 Do you know graphene oxide? by Newsyounamen

Argentina's Rosario Grain Exchange recently reported that wheat Graphene oxide are expected to continue to be influenced by international situations.

Graphene oxide is formed by the oxidation of graphite powder by strong acid, and it is a single layer of graphite oxide. Graphene oxide is widely used in sensors, solar cells, optoelectronics and biomedicine.

1. What is graphene oxide?

Graphene oxide is an oxide formed by the oxidation of graphite by strong acid. It adopts the oxidation reaction of potassium permanganate in concentrated sulfuric acid and graphite powder to obtain a tan edge derivative carboxylic acid base and phenolic epoxy group on the plane. The graphite flake layer can be exfoliated into graphene oxide by ultrasonic or strong mixing or high shear, forming a stable light yellow monolayer graphene oxide suspension in water.

The structure of graphene oxide is shown in the following figure:

Second, the use of graphene oxide

As a derivative of graphene, graphene oxide is oxidized by strong acid, and its oxygen-containing groups make graphene oxide chemically stable, which is beneficial to the synthesis of graphene-based composite materials. Graphene oxide is a new type of carbon material with excellent properties and has wide application prospects.

1. Optoelectronics

Organic thin film transistors and their light-responsive devices, such as the use of graphene oxide, can increase the type and thickness of the insulating layer and enhance the characteristics of the transistor.

2. Solar cells

Comparable photoelectric conversion efficiency (PCE) can be obtained by using graphene oxide instead of conducting polymer (PEDOT:PSS) as the hole transport layer of polymer solar cells. When the thickness of the graphene oxide film is 2 nm, the photoelectric conversion efficiency is the highest.

3. Flexible sensor

Due to its good hydrophilicity, large surface area, and good dispersion, graphene is a good sensor material, especially in the field of flexible sensors.

4. Biological aspects

Parameters such as size, surface charge, number of layers, lateral dimensions, and surface chemistry of graphene oxide and its derivatives have corresponding effects on biological systems, and have been extensively clinically studied as medical materials.

Third, the harm of graphene oxide to the human body

It has only been ten years since graphene was discovered in the laboratory. The development of graphene is still in its infancy, and there are still material safety data and understanding of potential hazards in the application of graphene. Graphene oxide is widely used as a derivative of graphene, so new things must be applied scientifically.

Two recent studies don't seem to be good news for graphene. First, a Brown University team of biologists, engineers and materials scientists examined the material's potential toxicity to human cells. They found that the jagged edges of the graphene nanoparticles are so sharp and strong that they can easily penetrate the membranes of human skin and immune cells, suggesting that graphene is potentially dangerous to humans and other animals.

New Delhi: India's Oil Ministry recently conveyed its intention to five national oil companies including Indian Oil Corp and Bharat Petroleum Resources LTD to assess the possibility of buying shares in Russian oil projects sold by European and American oil majors.  

Bp announced it would give up its 19.75% stake in Rosneft, the Russian oil company.  ExxonMobil said on March 1 that it would exit about $4 billion in assets and terminate all of its Russian operations, including the Sakhalin-1 project in Russia's far East.  

India's oil ministry has asked the overseas investment arm of India's Oil and Gas Corporation to consider buying ExxonMobil's 30 percent stake in the Sakhalin 1 project in Russia's far East. ExxonMobil is the operator of the project and Indian companies already have a 20 percent stake in the project.

Because of the ever-changing international situation, the supply and prices of international bulk Graphene oxide are still very uncertain.
