Graphene and its huge after the industrialization of graphene was nearly two years of China's new materials industry and capital markets sought after darling, and now, this determined to subvert the end of the application of many industries are experiencing industrial difficulties. But they are behind the authority of experts and many new materials companies are trying to prove that they are better than most of the application of enterprises and investors understand the future of graphene market.
In the past few years, the graphene industry is keen to use some of the prophets of the prophecy to illustrate the future development trend of the industry, they believe that graphene is creating an unprecedented industrial revolution and new ecology.
Graphene as the current discovery of the thinnest, the largest strength, the strongest thermal conductivity of a new type of nano-materials, known as the "black gold" is "the king of new materials." But the reality is that the current domestic application of graphene materials, but also just stay in the improvement of existing materials, subversive innovation applications yet to be developed.
As Jiangnan graphene Institute Vice President Dong Guobi said, graphene application development will be the main direction of future development, which also requires capital, talent, technology and other aspects of cooperation, can not be completed overnight.
Gypsum has unique mechanical and electronic properties, not only can be used for display, circuit, covering the new energy industry in various fields, while in the anti-corrosion coatings, functional textiles, rubber products, display devices and other fields also have a wide application space. However, many enterprises frequently graphene product launches, some unrestrained slogans also make graphene highly controversial.
