Top 10 applications and top 10 news of graphene in 2020
2020 has been a challenging year for any industry, and it is no different for the graphene industry. However, practitioners and academic researchers in the graphene industry have not slowed down the pace of scientific research, and many have quickly adapted to the status quo and created high-quality solutions and advanced technologies based on graphene.
Israel Graphene Information Network selected the top ten graphene application fields in 2020 according to the quantitative ranking of scientific and technological references indexed by the website. The most popular of these are undoubtedly the fields of medicine and sensors. The specific top ten graphene application rankings are as follows:
(1) Medical and Public Health; (2) Sensors; (3) Batteries; (4) Composites; (5) Automotive Applications; (6) Coatings; (7) Supercapacitors; (8) Thermal Conductivity Applications; (9) ) conductive ink; (10) electronic products.
In addition, due to the raging of the new crown epidemic, the development of all walks of life has consciously or unintentionally tilted towards the war. Among the top ten graphene news in 2020 selected by the Israel Graphene Information Network, most of the events are related to the use of graphene technology to fight against the new coronavirus, which also shows the importance of graphene in the medical and public health fields. effect. The details of the top ten news are as follows:
1. How can graphene help people fight the new coronavirus?
As researchers and companies around the world begin to battle the Covid-19 pandemic, many are revisiting graphene as the material with the most potential to win the fight. Graphene's known antibacterial/antiviral properties, its beneficial properties for medical devices, sensors, and related devices, etc., all prove to be useful.

Author's point of view: In 2020, due to the outbreak of the new crown epidemic, masks have become a key word throughout the year: it is Taobao's top ten best-selling products in 2020, with a cumulative search of more than 7.5 billion people; BYD relies on it to become a mask shipment The number one in the world; Trump lost the president because of the "election fraud" it caused, and Biden because it not only successfully regained power, but also basically gave the Democrats control of the Senate and the House of Representatives; China is helping it Xia was the first to break free from the quagmire of the epidemic. Masks have become a must-have item in our lives, both now and in the future. However, the shortcomings of disposable masks with short timeliness and insufficient epidemic prevention performance are gradually exposed. Although the price of masks is not expensive, it still causes pollution and waste. Graphene has good properties of blocking viruses and bacteria, and has become the best partner of this medical and health product. In 2020, many manufacturers around the world have launched graphene masks, which can be worn for a longer time, with stronger anti-virus and antibacterial effects, higher comfort, good dust-proof and anti-static properties, and even some products can achieve natural cleaning. reuse. The combination with the mask maximizes the low-cost application of graphene, thereby further expanding the influence of graphene and promoting graphene to play a larger and more important role in the field of public health and medical health. However, the short interlude will only affect the temporary development trend. In the future, the main application fields of graphene will still focus on high-end structural materials and electronic information functional materials.
At the beginning of the month, the overall price of flaky graphite in Shandong was stable. At present, the mainstream price of -195 was 6300-6500 yuan / ton, which was the same as last month.
The new material industry is a strategic and basic industry of the national economy
To keep the working temperature of each part of the PC within a reasonable range, in addition to ensuring that the temperature of the PC working environment is within a reasonable range, it is also necessary to Perform heat dissipation treatment.
As we all know, the working temperature of an electronic device directly determines its service life and stability.
