According to Korean media news, the research group of Chungnam University in South Korea omitted the necessary transfer process when processing graphene, and used titanium to develop a new high-quality large-area graphene synthesis technology
at low temperatures.
The research results were published in ASC Nano, an international academic journal in the field of nanotechnology
.
It is understood that graphene has good electrical conductivity and thermal conductivity, high mechanical strength, softness and transparency
.
Therefore, it can be widely used in secondary batteries, displays and other fields
.
When synthesizing graphene by general chemical vapor deposition method, it is necessary to carry out transfer engineering on other substrates, but many problems will arise in this process, such as the need to overcome internal bonding, adhesion problems with substrates, the area size and control interface of graphene crystal surfaces, and low characteristics due to folds on the graphene surface
.
The research team found that titanium has the same crystalline structure as graphene and is very strong in binding to carbon
.
Using the research results of titanium to remove graphene folds, graphene synthesis technology
was developed on a 10nm thick titanium layer.
This technology can synthesize high-quality graphene under low temperature conditions of 150 degrees, which greatly improves the efficiency and application of
engineering.
The research group said that the research can make up for the shortcomings of existing graphene materials, and can directly develop a new concept large-area graphene manufacturing technology
.
Graphene can not only be applied to transparent and soft electronic components, but also replace existing metal electrodes
such as gold and copper.
