Summary of the various applications of nano graphene on mobile phones

Graphene nanopowder is a two-dimensional material. Carbon atoms are arranged in a hexagonal shape and are connected to each other to form a carbon molecule. Its structure is very stable. As the number of connected carbon atoms increases, the two-dimensional carbon molecule plane keeps expanding, and so does the molecule. A single layer of graphene nanoparticles is only one carbon atom thick, that is, 0.335nm, which is equivalent to 1/200,000 of the thickness of a hair. There will be nearly 1.5 million layers of graphene in 1 mm thick graphite. Graphene is the thinnest known material and has the advantages of extremely high specific surface area, superior electrical conductivity and strength. The existence of the above advantages is that it has a good market prospect. Various applications of nano graphene on mobile phones are as follows:

Screen

Graphene screens can use force sensors, bringing a new dimension to touchscreen technology. Furthermore, thanks to graphene’s high toughness, these new properties can be integrated into flexible screens, which are useful for wearable technology.

Phone case

Graphene is a high-strength material. Mixed with resins and plastics, or even just as a coating, graphene could be used to make safer helmets, stronger aircraft parts and more durable building materials. Combining graphene with a phone’s case could make it even stronger, and we might never have to worry about it falling off again!

Antennas and Communications

Graphene could boost optical data communications to unprecedented rates while reducing energy consumption and transmission errors. By 2020, the graphene flagship aims to link more than 400 gigabits of data per second. Graphene can also serve as the basis for flexible near-field communication (NFC) antennas, enabling new technologies such as electronic banknotes or smart wallets.

Sensors

Graphene sensors have many applications: linking to health sensors throughout our bodies, monitoring high-risk infections, oxygen and sugar levels, correcting our posture, and even helping us track neurological pathologies. Sensors can also detect and analyze our environment.

Processors and Electronics

Graphene’s electronic properties allow us to make faster and more reliable phone accessories. Graphene has high strength, conductivity, yet thin — just one atom thick, enabling thinner and faster microprocessors for smart products and the Internet of Things. Graphene and related materials are so flexible that devices can be integrated into textiles or even ‘stickers’ directly on the skin.

Battery

Graphene can be used to improve the capacity, efficiency and stability of batteries. Graphene batteries can have higher energy storage and better performance in terms of service life and charging time. Graphene and related materials can also be used to improve the performance of other energy storage solutions, such as supercapacitors. Another role of graphene in graphene-based lithium-ion batteries is to improve heat dissipation.

Headphones/Speakers

Graphene could make headphones and speakers more energy-efficient and lighter, while producing better sound. As membranes become lighter, they are often too FL releasable and generate unnecessary vibration and noise. Graphene is flexible and strong, so distortion is reduced and people can enjoy their favorite music sources with unprecedented clarity!

Graphene-Corrine

Graphene! corrosion-resistant property of a human hair thick coating can up to 3000 hours.

The thickness of 100 thousand layer graphene equals to the diameter of one human hair. Well, how it would work if applied on coating?
On the “Nano Graphene modified anticorrosion coating technical report” held in Jiangsu a few days ago, a company brought out a thinnest graphene heavy-duty coating, whose corrosion-resistant property could be up to 3000 hours, which was three times than that of American heavy-duty coating.
It’s all known that to provent metal corrosion is an international problem.The common method of anti-corrosion is to paint the metal to prevent it from contacting with air and water. Such method can only make metal not be corrision in a short time and it requires regular maintenance and has certain limitations.

Graphene is the lightest, thinnest, highest strength, best electrical conductivity and thermal conductivity of nano-scale new materials and can enhance the performance of raw materials in many applications.
Graphene heavy anti-corrosion coating making use of good conductivity and sheet lap characteristics of Graphene, adds the modified graphene into the anti-corrosion coating system, forming a good conductive network with Zinc powder and to achieve a breakthrough that still have excellent cathodic protection and corrosion resistance under the condition of the low Zinc.

According to expert said that the combination of graphene and coating made amount of Zinc nano powder only 1/3 of the traditional corrosion-resistant coating and it dramatically reduced the pollution of Zinc vapor. At the same time, graphene heavy-duty coating is the known thinnest corrosion-resistant coating, which can meet the demand of lightweight coating.

When you buy Nano Graphene Oxide and other carbon nanomaterials from Hongwu nanomaterial, you can be certain you’re getting the finest product at the best possible price.

Significant applications: Graphene is used to detect cancer cells for the first time!

Although graphene has not been widely used yet, but researches on it have never stopped.

Graphene is a planar film composed of carbon atoms in the hexagonal heterogeneous lattice of sp2 hybrid orbitals, and is a two-dimensional material with only one atomic layer thickness. Its conductivity, thermal conductivity, strength, stability are very strong, known as “the king of new materials”, may have a subversive impact on the entire industry.

Can graphene be used to detect cancer cells?
Researchers at the University of Illinois at Chicago have found that cells and graphene interact to distinguish active cancer cells from common cells by Raman imaging, which makes graphene promising for early detection of cancer. The study was published in the American Chemical Society “Applied Materials & Interfaces”.

What is the mechanism by which graphene can be used for cancer detection? “Graphene, the thinnest two-dimensional material known in the world today, is sensitive to changes in its surface,” says Vikas Berry, associate professor of chemistry at the University of Tokyo. “The interaction of graphene and cells leads to the distribution of charge in graphene rearrangement, changes the energy of atomic vibrations, such changes can be detected by Raman spectroscopy.As the cancer cells are more active, easily lead to a higher negative charge on the surface, which can distinguish whether there exist cancer cells.

The technology is still in the experimental stage of cancer mice. The results showed that the technology is very promising, and it will be further tested for patients with living tissue for testing. At the same time, the technology is also committed to distinguish between other types of normal cells and cancer cells. “Once the patient has a brain tumor, we can use this technique to see if the tumor recurs after surgery,” says Berry. “To do this, we need a sample of cells that can interact with graphene to see if cancer cells are still there.”

Earlier this year, Berry and his collaborators also studied nanoscale ripples in graphene, which showed different electrical conductivity in the vertical direction, which was useful for electronics.

With outstanding properties, such as large specific surface area, high conductivity and good flexibility, thinnest and strong strength, Graphene is supposed to make great contributions to human being in various aspects of life!
