Academician calls on graphene industry not to stage a "great leap forward"
Time：2023-05-06
"The development of the graphene industry should be solid, to do highly sophisticated 'killer' applications, can not be satisfied with only doing products regardless of the future, such as graphene underwear and belts now popular on the market, but also can not rush, vigorously engage in the 'great leap forward' movement of the graphene industry." Liu Zhongfan, an academician of the Chinese Academy of Sciences and a professor at Peking University, pointed to a picture of "steel refining" on the screen, prompting a tacit laugh from the audience. This is the scene of the "2017 China Graphite New Material Industry Development Forum" held in Harbin on January 10.
On the same day, more than 100 domestic scholars, discipline leaders and core enterprise leaders in the field of graphite new materials gathered in Harbin to participate in the "China Graphite New Material Industry Development Forum" sponsored by the China Graphite Industry Development Alliance. The forum aims to promote the industrialization process of scientific research achievements of new graphite materials and promote the graphite industry to enter a stage of healthy development.
"The ideal is very plump, the reality is very skinny." Academician Liu Zhongfan said that research in the recent period has shown that there is a big gap between ideal and reality for graphene materials. "Ideally, the single crystal graphene structure has a perfect honeycomb shape, but the actual graphene observed is a polycrystalline film or powder made up of single crystal fragments, like a torn piece of clothing, with a lot of dirty stuff," he said.
Harbin, Qitaihe, Suzhou... Academician Liu Zhongfan made a graphene industrial park distribution map, there are nearly 20 graphene industrial parks in the country, "whether it is developed areas, or remote areas, are under construction graphene industrial parks."
Academician Liu Zhongfan believes that the graphene industry is a big cake, but how much can be divided is still unknown, which requires researchers and related enterprises to pay attention to the core technologies that lead the future.
He said: "Graphene cannot be like a 'silver bullet', not all products need to use graphene." He felt that some graphene products lack technical content, different from the graphene belt and other products on the market, Academician Liu Zhongfan and his scientific research team are studying super graphene glass, using the direct growth technology of graphene on traditional glass, so that graphene can ride the glass carrier, obtain a new graphene glass, and give the glass new functions through graphene. Such as electrochromic Windows, liquid crystal smart Windows, glass radiators, high-efficiency cell culture dishes... These are the research results of Liu Zhongfan's team. He said that the cell culture dish made of graphene combined with glass, the cell proliferation efficiency is at least twice as fast as the ordinary dish.
For the number of graphene-related patents in China ranked first in the world, he pointed out that the state encourages the application of patents, but should pay attention to which patents really have protection value. He is optimistic about the development prospects of graphene in China, and believes that labeled graphene films are the only way for the development of graphene.
Academician Liu Zhongfan cited Gartner's technology maturity curve analysis that the graphene industry is still in its early stages. He suggested that the relevant enterprises work hard and persevere: "Graphene is a real industry, the most need is to persist." Graphene industry needs' craftsman spirit ', need time accumulation, need time investment."
"From the Stone Age to the Bronze Age to the Steel Age." At the forum, Academician Liu Zhongfan reviewed the history of human civilization, "Now entering the silicon era." He looks forward to and will actively participate in promoting the arrival of the "graphene era".
Academician Liu Zhongfan and Tsinghua University professor Gai Guosheng and other experts emphasized that the preparation determines the future, the future of graphene also depends on equipment manufacturing, only the development of graphene industry with equipment basis, there will be high-quality, high stability of graphene materials.
In January 5 this year, graphene industry experts for Heilongjiang Qitai River pulse carbon era graphene development future, academician Qian Yitai of the Chinese Academy of Sciences has also said that the development of graphene requires stability, not fast: "public opinion to build, but moderate."
