What are the closest graphene applications to practicality?

Graphene has too many advantages and has a wide range of applications, such as solar cells, sensors, nanoelectronics, high-performance nanoelectronic devices, composite materials, field emission materials, gas sensors and energy storage. As far as I know, its biggest application is in the field of semiconductors. However, at present, most of them are still theoretical, which needs to be studied in depth.

Graphene in circuit design helps solve thermal management problems that exist in advanced high-speed, high-integration-density chips.

Modulation that can be achieved with graphene circuits is necessary to otherwise not be able to achieve phaseshiftkeying and frequencyshiftkeying, which are widely used in wireless applications such as Bluetooth, RFID and Zigbee," Mohanram explained to NanoWerk magazine. Compared with the complex design techniques used in conventional designs, which are based on multiple unipolar transistors, our amplifiers have many advantages, such as simple structure, low parasitism, high bandwidth and low power consumption. The progress that has been made is in graphene-based films, which can be used to make transparent and printable electronics, such simple circuits with high performance and field configuration capabilities, which will inevitably lead to large-scale integration and industrialization."

The important applications of graphite include graphene integrated circuits, graphene batteries, graphene touch screens, graphene slag supermaterials, etc., which have important application prospects in materials science, micro-nano processing, energy, biomedicine and drug delivery.

1. Graphene integrated circuits, due to the super transmission performance of graphene and the very good thermal conductivity of the state, graphene is also considered to replace the material of silicon raw materials, and graphene should become the next circuit board material of the next generation.

2. Graphene battery, in the production of batteries, can be used as a high-end material for positive and negative electrodes, graphene can also be used as a conductive "additive" to increase the efficiency of the battery in the positive and negative electrodes, and the battery that increases graphene can generally improve the overall efficiency of the battery.

3. Graphene touch screen, the key component of a smartphone is a conductive and very transparent touch screen. Due to the extremely good flexibility and excellent conductivity of graphene, a material with excellent electrical conductivity, and very outstanding optical permeability, graphene can be used in the production of mobile phone screens, and graphene is also better than the current material indium tin oxide.

4. Graphene supermaterial, researchers use tiny tubular graphene to form honeycomb structure foam materials. It's as light as a balloon but strong as metal. In the future, it can be used to make bulletproof vests, tank armor, etc.

1. Lithium battery. Researchers at Rensselaer Polytechnic Institute in the United States have made the performance of high-speed channels for lithium ions in lithium-ion batteries. This graphene anode material can be charged or discharged up to 10 times faster than the graphite anode commonly used in lithium-ion batteries today.

China Metal Research Institute has developed a flexible lithium-ion battery that can be quickly charged and discharged with graphene as a current collector;

2. Mobile phone. In 2013, Nokia had planned to use graphene to replace the transparent indium oxide conductive layer widely used in LCD touch panels, as well as other high-frequency electronic components. Graphene is applied to circuit boards, flexible materials and simple stool integrated multi-point sensing platform;

3. Bandages, food packaging and even antibacterial T-shirts. Chinese researchers have found that bacterial cells cannot grow on graphene, while human cells are not damaged.

Graphene has a wide range of applications in life. The details are as follows:

Energy. Graphene has extremely high electrical and thermal conductivity, which can be used to make high-efficiency batteries and supercapacitors to improve energy conversion efficiency.

Electronics. Graphene has an extremely high carrier mobility and can be used to make high-speed, high-performance transistors and integrated circuits, as well as flexible displays and touch screens.

Biomedicine. Graphene has good biocompatibility and can be used to make biosensors and drug delivery systems, antimicrobial textiles and medical devices, etc. Materials science.

Graphene has high strength and toughness, and can be used to make high-strength materials, as well as hydrogen storage materials with high specific surface holding area.

In addition, graphene can also be used to make artificial organs and cell detectors, to provide patients with faster and more accurate solutions, as well as to manufacture various electronic devices.

Graphene in life, generally like the battery of an electric vehicle, is generally the first brand of Shida Debate Graphene. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano fabrication, energy, bypass biomedicine, and drug delivery, and is considered to be a revolutionary material in the future.

1.Anti-rust: Since graphene does not dissolve in water, polymers can be mixed for anti-rust coatings.

2.Graphene is insoluble in water and has ultra-high electrical conductivity, and if it is combined with steel, it can prevent steel from coming into contact with water and alleviate the electrochemical reaction of iron oxide to achieve anti-rust effect.

4.Capacitors can store electrical energy, such as the flash of a camera, which it relies on to provide energy.

5.Flexible electronic circuits: to increase the computing speed of computers by 50 times, the most important material for computer chips is silicon.

6.Graphene, on the other hand, conducts electricity better than silicon, uses less electricity, generates less heat, and can even eliminate cooling fans, and can be up to 50 times faster.

7.Speaker: The sound generation principle of this type of speaker is that graphene makes sound through the thermal energy generated by the transmission of electric current.

8.If you put a layer of graphene less than one nanometer thick on glass and two types of plastic (two different types), and then apply alternating current, you can hear the sound.

9.Instead of vibrating through a diaphragm, this speaker emits sound through graphene transporting an electric current, and its biggest advantage is that it is thin and flexible, and can be made into any shape.

10.Water purification: The strong adsorption capacity of graphene can effectively control water pollution.

11.The graphene filter element can filter out sediment, heavy metals, and chemical residues, and the sterilization rate can reach more than 90%, and the filtered water is sweet and delicious, and the service life is longer than that of activated carbon, which solves the trouble of frequent replacement of the filter element.
