The Practical Products Of Graphene Are Divided Into Two Categories First, graphene material profile Now the world is not a clear definition of graphene. 2004 British University of Manchester scientists Andrei Heim and Constantine Norfolkov found monolayer graphene. They were awarded the 2010 Nobel Prize in Physics for their excellent research work on graphene materials. Therefore, the initial graphene only refers to a single layer of carbon atoms from the single structure of the new material, is only one carbon atom thickness of the two-dimensional material. However, follow-up studies show that, from the electrical nature of the two and three, and even ten layers of carbon atoms also have their own special physical properties, the current thickness of 10 layers of carbon atoms within the sheet of graphite material is defined as graphene The argument is gradually recognized by academics. The recently established China Metalsene Union Standardization Committee found that the thickness of 10 layers of carbon atoms in the material belongs to the graphene range. Graphene is a magical material, as long as the addition of a little into other materials may have a magical effect, worthy of the material sector "super material." Graphene not only "thinnest, strongest", as a thermal conductor, it is better than any other material's thermal effect. Using graphene, scientists can develop a range of new materials with special properties. Because of its very low resistivity, electron migration is extremely fast, it is expected to be used to develop thinner, faster conductive chips, replacing silicon. Since graphene is essentially a transparent, good conductor, it is also suitable for making transparent touch screens, light plates, and even solar cells. Super capacitors and chips, is the world's focus on the study of graphene field, but also the future of the culmination of the revolutionary progress of graphene. The application of graphene must be a process that extends from the low end to the high end. The use of low-end applications of conductivity of graphene will rise in the past two to three years, and the use of photovoltaic cells and replace the silicon chip chip area, still takes a long time. Second, made of graphene The practical products of graphene are divided into two categories: graphene film and graphene powder. There are many ways to prepare graphene in the laboratory (see figure below). However, the way of mass production of graphene is mainly two kinds: one is the use of chemical vapor deposition in the metal surface to grow a single layer rate is very high, large area of graphene film material; one is the natural graphite through physical or chemical The method of crushing, the formation of graphene powder. The graphene powder looks like a very fine black powder. Domestic graphene powder and graphene film has been equipped with mass production capacity, is expected to a series of industrial applications of graphene will be large-scale roll out. As a high-tech material, graphene powder production process, research and development, technology and equipment are very important, the production of labor costs are very small. The annual production capacity of 50 tons of graphene powder business, the production process only a few workers only.

Praktični proizvodi grafena su podeljeni u dve kategorije Prvo, profil grafenskog materijala Sada svet nije jasna definicija grafena. Naučnici iz Britanskog univerziteta u Mančesteru 2004. Andrei Heim i Konstantin Norfolkov pronašli su monolojni grafen. Dobitnici su Nobelovu nagradu za fiziku 2010. godine za odlične istraživačke radove na grafenskim materijalima. Prema tome, početni grafen se odnosi samo na jedan sloj atoma ugljenika iz jedne strukture novog materijala, samo je jedna debljina ugljenikovog atoma dvodimenzionalnog materijala. Međutim, studije praćenja pokazuju da, iz električne prirode dva i tri, pa čak i deset slojeva atoma ugljenika takođe imaju svoja posebna fizička svojstva, trenutna debljina 10 slojeva atoma ugljenika u sloju grafitnog materijala je Definisani kao grafen. Argument postepeno priznaju akademici. Nedavno uspostavljeni odbor za standardizaciju sindikata metala u Kini otkrio je da debljina 10 slojeva atoma ugljenika u materijalu pripada grafenskom rasponu. Grafen je magični materijal, sve dok dodavanje malo u druge materijale može imati magični efekat, zaslužan od materijala materijala "super materijal". Grafen ne samo "najtanji, najjači", kao toplinski provodnik, već je bolji od termičkog efekta bilo kog drugog materijala. Koristeći grafene, naučnici mogu razviti niz novih materijala sa posebnim osobinama. Zahvaljujući veoma niskoj otpornosti, elektronska migracija je izuzetno brza, očekuje se da se koristi za razvijanje tankih, bržih provodnih čipova, zamenjujući silicijum. S obzirom da je grafen u osnovi transparentan, dobar provodnik, pogodan je za pravljenje transparentnih ekrana osjetljivog na dodir, svjetlosnih ploča, pa čak i solarnih ćelija. Super kondenzatori i čipovi, svetski fokus na proučavanju grafenskog polja, ali i budućnost kulminacije revolucionarnog napretka grafena. Primena grafena mora biti proces koji se proteže od donjeg do visokog kraja. Korišćenje low-end aplikacija provodljivosti grafena će se povećati u poslednje dve do tri godine, a korišćenje fotonaponskih ćelija i zamena površine čipova silicijuma, još uvijek traje dugo. Drugo, napravljeno od grafena Praktični proizvodi grafena podeljeni su u dve kategorije: grafen i grafen u prahu. Postoji mnogo načina za pripremu grafena u laboratoriji (pogledajte sliku ispod). Međutim, način masovne proizvodnje grafena je uglavnom dve vrste: jedna je upotreba hemijskog taloženja talasa u površini metala da bi se postigla jedinstvena stopa sloja je vrlo velika, velika površina grafenskog filma; Jedan je prirodni grafit kroz fizičku ili hemijsku metodu drobljenja, formiranje grafenskog praha. Grafeni prah izgleda kao fini crni prah. Domaći grafeni prah i grafeni film opremljeni su masovnim proizvodnim kapacitetom, očekuje se da će niz industrijskih primena grafena biti u velikoj meri. Kao visokotehnološki materijal, proces proizvodnje grafenog praha, istraživanje i razvoj, tehnologija i oprema su veoma važni, proizvodnja troškova rada je vrlo mala. Godišnji proizvodni kapacitet od 50 tona grafenskog praha, proizvodni proces samo nekoliko radnika.
