Graphene, a substance that cannot be found in the real world and needs to be refined, is thought to bring great changes to the world. At present, industry experts said in an interview that there is no problem in the mass production of graphene, but the application remains to be explored.
Recently, Professor Gao Chao of Zhejiang University has developed a successful aerogel “carbon spongeâ€, which adds a new perspective to the application of graphene.
Shen Wanci, a carbon material expert and chairman of the China Non-Metallic Mining Industry Graphite Association Expert Committee, said in an interview with the Securities Times reporter that from the published parameters, the carbon sponge is still only a laboratory product, a graphene and carbon. The materials that are combined with nanotubes should be further studied for specific application. There are no mature products at home and abroad.
Feng Guanping, former dean of the Research Institute of Tsinghua University in Shenzhen, began to study graphene after 2008 and introduced the team from overseas. Feng Guanping told reporters that the current industrialization of graphene includes two paths, one is the mass production of graphene raw materials, and the other is large-scale investment into the application field. “Now the industry has initially had the ability to produce graphene raw materials in large quantities. The application of graphene is also clear in two areas.â€
According to Feng Guanping, there are two main methods for producing graphene in the mainstream, one is vapor deposition and the other is stripping. The graphene produced by vapor deposition is in the form of a large transparent film, which can be used as a mobile phone screen instead of ITO (Indium Tin Oxide) conductive glass. It has cost advantages and environmental benefits. It is expected that the graphene screen can be mass-produced within one or two years. Phone. The graphene produced by the oxidation method is a small piece of black, which can be used in the energy field in the future, but there are not many mature products at present. For carbon sponges, Feng Guanping believes that this is only a primary application of graphene, and the application prospects will not be great.
Professor Gao Chao, the maker of carbon sponge, said in an interview that he is using graphene to produce graphene. "Now there are companies talking to me. If you talk about it, you can quantify the production of graphene by entering the capital, and you can also quantify it into a carbon sponge." Gao Chao did not disclose the names of these companies, but he said that his transfer fee is not It will be higher than the price of the technology transferred by the Ningbo Institute of Materials of the Chinese Academy of Sciences to Shanghai Nanjiang Group.
Shen Wanci told reporters that the graphene produced by the oxidative stripping method is very small sheet, and how to apply it is a relatively big problem. Because reassembly will result in the boundaries of the splicing combination, which will affect the structure and strength of the material. The graphene produced by the vapor deposition method is a large piece, and the quality is good but the cost is high. The former requires technological breakthroughs while the latter requires cost solving.
