Graphene, known as the “miracle material”, is a two-dimensional crystal with only one atomic thickness separated from graphite and composed of carbon atoms. Graphene has high performance in multiple dimensions such as electricity, heat, light, and force that no other material can match. With the continuous breakthroughs in industrial technology and the continuous development of various downstream applications, the commercial application process of graphene materials will continue to accelerate. The future graphene market has huge prospects and is expected to give rise to a trillion-level new market.
Increase application volume and drive downstream markets
The China Graphene Industry Alliance predicts that the current global graphene annual production capacity will reach 100 tons, and will reach 1,000 tons in the next 5 to 10 years. By 2020, the global graphene market will exceed 100 billion yuan, of which the supercapacitor market in the new energy industry will exceed 53.4 billion yuan; the composite materials market will exceed 37.2 billion yuan; and the electronic information industry will reach 26.7 billion Yuan. China will play a leading and core role in the global graphene industry, accounting for 50% to 80% of the global market.
China’s graphite ore reserves are more than 55 million tons, accounting for about 77% of the world’s total, and its resource advantages are obvious. At present, China has a certain foundation for the development of graphene industry. It is reported that China accounts for about 40% of the world’s patents in the field of graphene, and has made certain achievements in industrialization. At present, graphene processing costs have dropped to one-tenth of those in 2011, and the quality rate and consistency have also been greatly improved, which is conducive to the expansion and development of downstream application fields.
Bulletproof and stealth, showing their talents in the field of military aviation
As early as two years ago, Spain’s “Abbesa” reported that graphene, a magical material, might become a military material that is harder than steel and can stop bullets. A recent bullet shooting experiment conducted by a team of American scientists also showed that graphene can quickly disperse the impact force and interrupt the abduction wave passing through the material. Its ability to withstand impact is far better than that of steel and aramid fiber composite material Kevlar (strength It is more than 2 times that of the same steel (5 times). Moreover, while improving bulletproof capabilities, it also greatly reduces the weight of bulletproof equipment.
In January 2016, Canada’s SUNVAULT Energy Company developed a graphene-reinforced resin protective sheet. It was tested with the world’s most lethal AK47 assault rifle bullet (which can penetrate 6mm steel plates within a range of 100 meters). It could not penetrate at all. , showing excellent protective properties. Based on the lightweight properties of this graphene-reinforced resin, researchers are further testing it against current British police body armor standards to determine its level of ballistic resistance.
In addition, graphene also has the ability to become invisible. In 2013, the University of California prepared a graphene-based infrared stealth coating, which achieves infrared stealth by changing the wavelength of reflected light. This material can be coated on large areas of structures and platform surfaces to achieve military camouflage.
A research team from Rice University in the United States combined epoxy resin coating with graphene nanoribbons to obtain a special coating material. Coat it on the edge of a helicopter rotor blade and apply a small voltage. The coating surface generates extremely high temperature electric heat, which can melt ice covering more than 1cm thick. In addition, this coating can provide electromagnetic shielding for aircraft and protect them from lightning strikes.
Far-infrared heating, the “light of life” in the field of health care
The St. Louis Times of the United States once published an article by Dr. Jiang Xinsheng of Oriental Rehabilitation Center on the medical effects of graphene’s far-infrared effect. The article mentioned that far-infrared rays with a wavelength of 5.6 to 15 μm in sunlight are essential for biological survival. The phenomenon of biological activation is called the “light of life” by experts, and the 8-14 μm far-infrared rays generated by graphene during the heating process are exactly the band suitable for human health. Therefore, carrying graphene products with such functions, It’s like asking an acupuncturist to regulate your meridian immune system. Undoubtedly, this is good news for computer users, mobile phone owners, drivers who sit for a long time and people with cervical spondylosis.
The upcoming graphene home smart heating painting only needs a small mural to bring warmth to the room. In addition to emitting infrared rays and intelligent temperature control features, it can also directly use solar cells to convert electricity. Data research has shown that it can save 70 million yuan. % of energy.
Based on this graphene heating technology, the “Fan Nuan Nuan” smart lunch box developed by Naomi New Material Technology is based on the principle of adding graphene powder to plastic, which can evenly simmer through the far-infrared spectrum under safe, low voltage and low power consumption. The heating mode can continuously heat for 3 hours without destroying the molecular structure of food, locking in nutrients and making the food taste good, solving various technical problems of traditional lunch boxes.
Charging king, flexible screen, leading the mobile world
A graphene battery only 1cm thick can fully charge a smartphone in 5 minutes, making it a charging king; the foldable LED transparent flexible screen can be used to watch movies, make phone calls and browse the web; RFID tags can be printed on ordinary paper. It can be folded repeatedly 150,000 times without loss of performance.
