Graphene is a carbon-based substance that is very interesting. It is the strongest substance (to date) to exist on Earth, consisting of one layer of carbon atoms. It is much stronger than steel and 200 times lighter than paper.
Graphene is a single-layered two-dimensional honeycomb lattice-shaped allotrope of carbon. Stacking layers of it result in the formation of graphite that is another allotrope of carbon. The graphene exhibits exceptional properties that make it a semimetal acting as an electrical conductor and a thermal insulator. The connection of atoms shows sigma bonds, which are the strongest kind of covalent bonds. Carbon nanotubes exhibit similar bonds and properties. For centuries it has been present on earth; however, in 2004, Andre Geim and Konstantin Novoselov of the University of Manchester rediscovered it (initial observation in 1962) and were awarded the noble prize for the same.
It has four outer shells, out of which three occupy three sp2 hybrid orbitals. Here means that it shares a combination of orbitals s, px, and py forming a sigma bond with the nearest atoms having a length of 0.142 nanometers. Its charge carriers show a linear dependence of energy on momentum. It can also absorb light, which is why the color is black. However, if one notices a single layer, it looks transparent. This property helps it rule in the optical industry.
Researchers have been experimenting on the material for quite a long, resulting in many exciting applications. Some popular types are Monolayer sheets, Bilayer, molded, Nano coil, Crumpled, Nanoribbons, and ligand/complex. It also uses as a fiber, 3D, Pillared, Quantum dots, and Reinforced, all of which are finding in the last decade. There are also many ways to formulate; however, we use the Catalytic chemical vapor deposition method (CCVD).
It is one of the most needed products reaching a $9 million market within 8 years of its discovery and will probably lead to $150 million by this year, i.e., 2021. This is a result of its exceptional properties and vivid application areas that make it remarkable in nanotechnology.
Graphene's Powder
powder or Nanopowder is one of the fantastic materials on the planet. It is a fine powder applicable in various technology fields and develops many other graphene's variations. It dispersed with multiple kinds of solvents to make products such as inks, sheets, and many more.
Graphene's Oxide
In oxidized form, known as graphene's oxide. It is also a single atomic layer material with a lace of oxygen groups. However, it is cheaper than the pure form. It readily disperses in water, whereas it is available in powder as well as dispersed form. It is used in the production of transparent conductive films.
Reduced Graphene's Oxide
The amount of oxygen molecules is reduced. The reduction is performed by electrochemical reduction, chemical reduction, and thermal reduction. Unlike graphene's oxide, this does not disperse in water quickly. It is useful for composite materials, conductive inks, sensors, and many more applications.
Graphene's Nanoplatelets
These are stacks of graphene of 100 micrometers and thickness of 1 – 15 nanometers. Typically, it is useful to make polymers like plastics, nylon, or rubber electrically or thermally conductive by adding small amounts of Nanoplatelets into it. These are similar to carbon nanotubes. They make non-conducting and semiconductor materials.
Graphene's Ink
These are unique kinds of inks that can transmit electrical pulses. This is because it contains solvents and graphene's powder. On drying, the inks can transmit electricity over a non-conductive surface such as fabrics and polymers. They are also used as electrical conductors and thermal insulators in many devices.
Graphene's Sheet
These are layers of single films, they possess the same properties. Their applications include touchscreen panels, PCBs, batteries, and radio-frequency identification tags.
Graphene's Gel / Aerogel
It is a combination of polymers and graphene. The liquid is then eliminated and replaced by air or any other gas. They are flexible and retain their original shape quickly after compression. Moreover, they can absorb 850 times their weight, resulting in useful activities like environmental cleanups, oil spills, etc.
Functionalized Graphene
There are three main types of functionalized.
Hydroxyl (-OH) is a functionalized group attached to graphene's 2D structure. The catalytic-chemical-vapor-deposition (CCVD) is the process used for the productions. Its application areas include aerospace, defense, research, and electronics.
Carboxyl (-COOH) is a functionalized group that is attached. It is non-conductive and can act as an insulator. Its applications include sports gear, research and development, and medical science.
Amine (NH2) is a functional group of nitrogen with a lone pair. Here graphene and nitrogen pair up is called amine graphene (GO-NH2). It is mostly useful as a catalyst in a chemical reaction, medical substitutes, and much more.

How to use as Coating Application?
The coatings available in the market are similar to SiO2 coating. One needs to adequately clean and prepare the surface. Any pollution on the surface might cause the coating to fail to adhere to the surface correctly. The preparation of the surface is critical to the product's performance.
Automotive Industry
Because it is the strongest substance on the planet, we use it to improve the strength of other materials. Dozens of studies show that adding even trace amounts to polymers, metals, or other materials may make them stronger – or lighter (as you can use less amount of material to achieve the same strength). Graphene's oxide is quickly diffused in organic solvents, water, and polymer matrixes since it is a carbon-based compound with oxygen capabilities. This compatibility as a filler with polymer coatings is essential because it allows automobile coatings to benefit from its "miracle-like" characteristics.
How its different from other Ceramic Coatings?
Silica oxide is common in conventional ceramic coatings (SiO2). One disadvantage is that traditional ceramic, silica oxide, and quartz coatings are susceptible to water stains. When we compare ceramic coatings to graphene's coatings, its claims to reduce heat on the surface of your paint, making water spotting much less likely.
The new world relies highly on speed! Almost everyone these days is ready to pay a little more for comparable high speed than they have. Everything we use today must be "Fast and smart" while being "simple and inexpensive." Graphene has garnered enormous interest due to its wide variety of remarkable and desired electrochemical properties, making it one of the best alternatives for use in energy storage applications. Energy storage is an important research topic that attracts much interest due to the demand for better energy device performance and a greener energy supply. It is essential in this technologically vital industry, highlighted by its electrochemical uses in energy storage devices, ranging from its use as a supercapacitor to batteries.
It has high diversity. The tensile strength is 130 GPa, which is 100 times more than steel. It has three times the heat conductivity of a diamond. At average temperatures, it is conductive and functions far quicker than today's conductors. It is composed of a single carbon atom. It considers having a high specific surface area, excellent conductivity, and a honeycomb-like structure, making it suited for battery applications.
Graphene's batteries, like traditional batteries, require two electrodes and an electrolyte solution to promote ion mobility. The composition of one or both electrodes distinguish batteries from solid-state batteries. Although carbon isotopes can be used in the anode, the shift occurs in the cathode. A standard battery's cathode is made entirely of solid-state materials. Still, the cathode of battery is made of a composite hybrid material that incorporates both solid-state metallic components.
It is a good choice for enhancing the efficiency of transparent batteries due to its high conductivity and transparency (up to 97.7 percent transmittance). As an electrode, it might be used in transparent energy storage devices, smart windows, solar cells, and other optoelectronic systems.
Over the last four decades, scientists and researchers have been working to increase existing batteries' overall electrochemical performance and reliability. They developed and tested several composite-equipped batteries. Researchers developed an optimal reduced oxide/silicon composite using a simple template self-assembly technique. The gravimetric and volumetric energy densities of current lithium-ion polymer batteries are lower than those based quasi-solid-state lithium-oxygen batteries. The system comprises a 3D porous cathode, a porous Li anode, and a redox mediator-modified gel polymer electrolyte.
Graphene batteries would allow cell phones to be slimmer or have larger battery capacity while maintaining their present dimensions. Fast device-to-device charging has fascinating ramifications as well. Electronics may charge each other at breakneck speeds with batteries capable of supporting extremely high currents and lightning-fast recharge and discharge durations.
Because of its large surface area, intrinsic mechanical flexibility, and remarkable electrical characteristics, it is viable for flexible batteries. Our Graphene-enabled lithium-ion batteries charge in a fraction of the time, all thanks to the great charger because it enables faster ion and electron movement in the electrodes. A lithium-ion battery atop flexible foam packed with nanoscale LiFePO4 cathode and Li4Ti5O12 anode materials, for example, may be fully charged in less than 18 seconds. The anode can also be composed of pure to boost capacity and charge or discharge rates.
With progression in technology, the word spreads faster than fire! The boom about Graphene's coating has also been doing rounds, and we bet you must have heard about it from someone or the other. The fuss is real when you don’t know much about technology. It is becoming more popular among detailers because of its toughness and anti-static qualities. Furthermore, its anti-static qualities prevent dust from settling on the surface coated with it. Exciting, isn’t it? Read on to know more!
Graphene's coating is a surface covering that is applied to an item. Graphene's coatings are among the most recent breakthroughs to hit the auto industry. One may use it for ornamental, utilitarian, or both purposes. Coatings are everywhere that you can see - on walls, furniture, cables and printed circuit boards (PCBs), the exterior of buildings and automobiles, and much more. Furthermore, the ornamental functions of coatings cover a wide range of applications. Colour, texture, and other aesthetic properties are the primary reasons decorative coatings are utilized. Functional coatings are used to modify the surface attributes, such as adhesion, wettability, corrosion resistance, wear resistance, and others. The coating adds an entirely new attribute to the end object in certain circumstances, such as magnetic response or electrical conductivity. Coatings can be employed in various methods, including vapour deposition, spraying, chemical and electrochemical procedures, roll-to-roll coating processes, and others.
