Overview:​How to prepare high quality, large size and low cost graphene on a large scale is an urgent problem to be solved in industrialization. Despite the rapid advancement of graphene research in the scientific community, which has attracted investment and attention, researchers are still cautious about its industrialization.

How to prepare high quality, large size and low cost graphene on a large scale is an urgent problem to be solved in industrialization.


Despite the rapid advancement of graphene research in the scientific community, which has attracted investment and attention, researchers are still cautious about its industrialization.


At present, many applications of graphene are still in the laboratory stage. Whether its magical properties can be fully demonstrated in application still needs further analysis and testing by scientists.


Most enterprises in the industry are still at the stage of tentative exploration. An important bottleneck is that the preparation of high quality, large size and low cost graphene for industrialization is not mature.


Nobel Prize winners Heim and Novoschlov obtained graphene in a way known as micromechanical stripping, which is still an important means of obtaining graphene for basic research in the laboratory. The graphene obtained by this method is of high quality, small size, labor-intensive and high cost. In the early stage of graphene research, the price of 1 square micron graphene prepared by micromechanical peeling even reached about one euro.


Other methods, such as chemical vapor deposition, can produce large areas of graphene, but the quality still needs to be improved, and the process is more complex. Solvent stripping method can achieve large-scale preparation of graphene, but it contains many defects.

Ballasted Solar Mounting Made In China

In 2009, Gao Hongjun team obtained high quality and large area graphene materials on the surface of ruthenium single crystal, and made a major breakthrough in the preparation method. However, Gao Hongjun believes that graphene can not replace silicon, in some ways, it may replace some of the functions of silicon. He said that silicon materials have been developed for decades, and their application is mature. It is not a new material that can be replaced or surpassed in a short time.


In the 1990s, carbon nanotubes (CNTs) became the star of the carbon nanomaterials family because of their excellent photoelectric properties. It is precisely because of the difficulties in their large-scale industrial applications that CNTs have not been able to meet people's expectations.


In some applications of graphene, it needs to be transferred to suitable substrates, and the interaction with substrates may cause some changes in graphene properties.


In order to realize industrial application of graphene, not only how to prepare high quality and large area materials, but also some key problems in device integration of graphene need to be solved. At present, neither of them has been well solved.
