Do you know graphene oxide?

Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.

Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."

According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.

The volatile oil prices in the international market will continue to affect lots of industries and the supply of many Graphene oxide.

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.
