What Is Graphene Oxide Nanoparticles and their Benefits?
May 30, 2022Graphene oxide is a type of carbon produced from graphite through oxidation, removing several hydroxyl functional groups from the graphitic structure. With this transformation, the material has some valuable properties not found in graphite and other forms of carbon. The material has high conductivity, high surface area, and nonpolar properties. These are essentially small particles used for many different applications because they have beneficial properties. The future potential of graphene oxide is high because it can be used to create materials with exceptional qualities such as transparency, biocompatibility, and mechanical strength that are not readily available today.
What Is Graphene Oxide?
It is a material that is made of carbon. It is an oxidized version of graphene, a two-dimensional single layer of carbon atoms arranged in a hexagonal lattice. Essentially, it is a material made up of carbon, oxygen, and hydrogen. Graphene is a material that has exceptional properties, such as high conductivity, high surface area, and nonpolar properties. Furthermore, it has high thermal conductivity and is a relatively good conductor of electricity. It is also transparent, biocompatible, and corrosion-resistant. It results from oxidizing graphite, which removes several hydroxyl functional groups from the graphitic structure. With this transformation, the material has some valuable properties not found in graphite and other forms of carbon.
Why is Graphene Oxide Important?
Since it is an oxidized form of graphene, it is expected to have high tensile strength, a large surface area, high electrical conductivity, and high thermal conductivity. These properties make it an appropriate material for flexible electronics, energy storage, and biomedical applications. It is a highly cheap material to produce. It can be used to create materials with exceptional qualities that are not readily available on the market today. Such materials could be used in flexible electronics, conductive inks, and biomedical devices. It can also be used as an additive in plastics, coatings, and paints to improve their properties or create entirely new materials. In this way, it could have a very significant impact on society.
How It Is Produced?
Generally, it is produced from graphite by oxidizing it with an oxidizing agent, such as oxygen gas or hydrogen peroxide. Such agents will convert the graphite into graphene oxide, which can then be separated from the oxidizing agent. It can also be produced by hydrolysis or thermal treatment of graphite. The graphite is first oxidized to graphite oxide, and then the oxidized product is treated with a base to transform it into graphene oxide.
Properties
- High electrical and thermal conductivity – It has high electrical and thermal conductivity, which can be adjusted by controlling the level of oxidization. It can be utilized as an additive in polymer matrices and other materials to enhance their electrical and thermal conductivity.
- High surface area – It has a large surface area, which can be used to increase the surface area of other materials.
- Transparency – It can be used to make transparent materials.
- Mechanical strength – The strength of it depends on the level of oxidation.
Benefits
Graphene oxide nanoparticles are essentially small particles used for many different applications because they have beneficial properties. Some of these properties are listed below:
- Conductivity – It has high conductivity, making it a good material for use in electrodes, batteries, and other electrical applications.
- Mechanical strength – Since these are tiny, they have high mechanical strength.
- Reduction of surface area – It has a large surface area but a relatively low level of chemical activity. This means that they are not easily oxidized or reduced.
- Biocompatibility – It is biocompatible.
Limitations
The main limitations of these nanoparticles are their low solubility in water and low dispersibility in organic solvents. Furthermore, they have high surface energy, making them hydrophobic and less soluble in water. These properties make it challenging to incorporate nanoparticles into solutions or dispersions and therefore, challenging to use in various applications. It is also difficult to reduce and oxidize, making modifying their structure and properties difficult.
