Product Details
Nitrogen-doped graphene can effectively modulate the structural properties of graphene through chemical modification of graphene, which is of great help to graphene and its applications in related materials.
Graphene is a single-layer two-dimensional crystal composed of carbon atoms, which exhibits excellent electrical, optical, thermal and mechanical properties. Modifying or modifying graphene through chemical or physical methods can improve the properties of graphene and expand its application fields. Among them, chemical doping is a very important and effective way to adjust and study the properties of graphene. Nitrogen is the most studied doping element for carbon materials.

Micromechanical exfoliation method
In 2004, Geim et al. successfully exfoliated and observed single-layer graphene from highly oriented pyrolytic graphite for the first time using the micromechanical exfoliation method. Geim's research group successfully prepared quasi-two-dimensional graphene using this method, observed its morphology, and revealed the reasons for the existence of the two-dimensional crystal structure of graphene. The micromechanical exfoliation method can produce high-quality graphene.
The mechanical exfoliation method is the method for producing the highest quality graphene, unlike other production methods which introduce defects into graphene.
Notes:
* Instructions for use: This product is used under oral conditions.
* Storage method: Store in a refrigerated and dry place, protect from radiation, protect from reducing agents, and keep away from light.
Shenzhen Turing Evolution Technology Co., Ltd. Company Profile
Shenzhen Turing Evolution Technology Co., Ltd. (abbreviation: Turing Technology) is located in Bao'an District, Shenzhen, with a registered capital of 31 million yuan. The company was initiated by Mr. Zhao Ping, a winner of the Second Prize of National Science and Technology Progress, and Professor Chen Hua, a well-known graphene expert in China. It is a leading domestic graphene enterprise, integrating the research and development, production, sales and application development of graphene. It ranks among the top in the industry in terms of technical level and brand popularity. It has successively been recognized as a "National High-Tech Enterprise", a talent unit of Shenzhen's "Double Hundred Plan", and a "Shenzhen Innovative Pilot Enterprise". It has passed the ISO9001 quality management system certification and is a director unit of the China Graphene Industry Technology Innovation Strategic Alliance, a director unit of the Guangdong Graphene Industry Technology Promotion Association, and a vice president unit of the Shenzhen New Materials Association.
Shenzhen Turing Technology firmly grasps the core technologies in graphene production and application, and is a pioneering and leading enterprise in the production of graphene powder using the physical method in China. All of the company's graphene products have independent intellectual property rights. It has applied for more than 40 graphene-related invention patents, and has obtained 21 national invention patent authorizations, 2 utility model patent authorizations, and two registered trademarks.
The company has carried out many pioneering works in the graphene industry. The company's team launched a graphene commercial research and development project in 2006, making it one of the earliest teams in China to start graphene commercialization projects. In 2009, it launched China's first batch of graphene products and China's first graphene enterprise standards, and is now actively participating in the drafting of industry and national standards for graphene. In 2010, Turing's pricing of graphene at 5,000 yuan per gram was called "graphene being 15 times more expensive than gold". In 2015, Turing Technology made a technological breakthrough, reducing the price of graphene powder to less than 1 yuan per gram, and it also built China's first graphene powder production line with an annual capacity of 5,000 tons, solving the industry-wide problem of high graphene production costs. The physical method for graphene production independently developed by Turing Technology solves the problems of waste acid and wastewater in graphene production, realizing clean production. Up to now, Turing Technology has developed the sixth-generation technology for producing graphene powder, enabling environmentally friendly, low-cost, and large-scale mass production of high-quality graphene.
Graphene can be widely applied in many fields such as new energy batteries, marine engineering, composite materials, thermal conductive materials, supercapacitors, seawater desalination, and biomedicine. In 2014, the company innovatively proposed the "Graphene+" concept, introducing graphene into application fields such as new energy, high-performance composite materials, and coatings, opening up a new situation for graphene applications. It has now launched graphene conductive agents dedicated to lithium batteries, graphene products dedicated to rubber and plastics, and graphene products dedicated to anti-corrosion coatings. Turing's graphene conductive agents for lithium batteries have successfully entered our daily lives.
Turing Technology, adhering to the corporate spirit of "Innovation Without Limits, Striving for Perfection", is creating a new chapter in the innovative application of graphene.
