Global Graphene oxide market trend 2023-2028 Do you know graphene oxide? by Newsfgjiaju

Rio de Janeiro, Brazil -- Vale today announced that it has completed a pre-feasibility study for its proposed nickel sulfate project in Quebec, Canada, a major milestone in the development of the project. This strategic move demonstrates vale's focus on delivering low carbon and high purity nickel Graphene oxide are still very uncertain.

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.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022. 

If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.

Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.

Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the Graphene oxide will develop in the future is still uncertain.
