Graphene Oxide

 

Since graphene production is quite costly and somewhat difficult to create, a lot of great effort is required to search for an effective yet cost-efficient method to make and use graphene derivatives or other related or similar materials. Graphene oxide or GO is a single atomic covered material created through the oxidation process of graphite which is abundant and highly cost-effective.

Graphene oxide is basically an oxidized structure of graphene that is laced with oxygen-infused groups; GO is also said to be easy to process since it can be dispersed or scattered in water or in other types of solvents, plus it can also be used to create graphene. Although GO is not one of the best conductors, there are some existing processes to improve its properties. Graphene for salemostly comes dispersed, in powder form, or as some sort of coating on various substrates.

 

There are four basic procedures to synthesize graphene oxide and these are Brodie, Staudenmaier, Hofmann, then Hummers. There are numerous varieties of these processes that exist along with enhancements that are constantly being studied to aim for better and more improved results, plus cheaper processes as well. The capabilities of the oxidation process are usually assessed by the ratio of carbon or oxygen of the graphene oxide.

 

When it comes to GO films, these can be essentially deposited on any substrate, then after, converted into conductors. This is the reason why GO is perfect for producing transparent conductive films such as those used in solar cells,flexible electronics, chemical sensors, and a lot more. GO is also known to be a replacement for ITO or tin-oxide on touch-screens and batteries. Moreover, these have an increased surface area so it can be used as an electrode component for capacitors, batteries, and also solar cells. Another key factor for using GO is that it is more cost-effective and easier to manufacture compared to graphene, making mass production and use highly efficient. Graphene oxide can easily be infused with varying types of materials such as polymers, plus, it improves the properties of composite materials such as elasticity, tensile strength, conductivity, and more.

 

When this is in solid form, GO flakes attach to each other until these are able to form a stable, thin and flat structure which can be wrinkled, folded, and even stretched. These types of structures can be used for functions such as ion conductors, hydrogen storage, and nanofiltration membranes. Additionally, some of the other properties of graphene oxide are fluorescent which makes its use great for various kinds of medical applications, disease detection, drug carriers, antibacterial materials, and bio-sensing are just a few of the possibilities that GO has for the field of biomedicine.

 

 

The functionalization of GO can essentially alter its properties which result in chemically adjusted graphenes that could become adequate and adaptable for numerous applications. Furthermore, graphene oxide is relatively cheap and very easy to find since there are a lot of graphene companies that currently sell it. However, it can get quite confusing since there are a lot of different companies that offer these with varying prices, form, quality, and more which makes it highly challenging and difficult to choose a specific product.

 

What is Graphene?

 

Carbon can easily structure three-dimensional or 3D lattices by connecting with four different carbon atoms that will eventually form a diamond pattern; also, it can just form two-dimensional or 2D sheets thonce it binds to three other different carbon atoms these will result in sheets that are generally known as graphene.

 

Information About Graphene

Graphene is known to be another form of carbon that is in the shape of a 2-dimensional, honeycomb lattice, and an atomic scale where a single atom forms every vertex. Graphene is also considered to be the basic structural component of other allotropes which include charcoal, graphite, fullerenes, and carbon nanotubes; furthermore, it can also be treated as an endlessly large aromatic molecule which limits the case of flat polycyclic aromatic hydrocarbons.

 

The graphene sheets mainly consist of carbon atoms that are connected in hexagonal shapes, with each atom covalently bound to three other varying carbon atoms; each of these graphene sheets are just a single atom thick and are considered as a single molecule only. Graphene has a similar form of carbon atoms that are also linked in hexagonal shapes; the shape, in turn, forms into carbon nanotubes yet the difference is that graphene is flatter instead of being cylindrical.

 

If someone asks what is graphene, one can state that it is considered among the thinnest and lightest compound known to man. Not only is graphene the thinnest and lightest compound, but it is also considered as one of the greatest conductors of heat; furthermore, it is also one of the best-known conductors of electricity since it has a high value of electron mobility. Aside from these, other important properties of graphene are the exceptional levels of light absorption and also its potential appropriateness when in use for spin transports.

 

With this in mind, it may be surprising for most individuals to know that carbon is considered as the second most copious mass found in the human body and the fourth most plentiful element found in the whole universe along with helium, hydrogen, and oxygen. Because of this, carbon can be the chemical foundation for all life form on Earth which generally makes graphene an eco-friendly and sustainable resolution for an unlimited number and variety of graphene applications. Ever since scientists have discovered and have mechanically obtained graphene, various scientific advancements have grown, especially in biotechnology and electronics where increased gains have been noted.

 

Generally, there is a wide range of graphene uses and these can be revolutionary and radical for various fields such as bioengineering; here, scientists wish to take advantage of the astonishingly tiny size of graphene so they can pierce through cell walls to insert a molecule depending on the choice of researchers. Moreover, graphene can also be used for creating ultra-fine antibiotic water filters for easy and quick filtrating techniques for conceivably dangerous drinking water.

 

Among one of the first applications and uses of graphene would be the graphene batteries and the super capacitors; so due to these uses and applications, experts have concluded that graphene may soon change the world by affecting the market with graphene-based equipment and gadgets. So if you come across the question, what is graphene? Just put it simply by stating that it is a thin layer or sheet of pure carbon tightly bound in a hexagon-like honeycomb lattice.
