Recently, the team of Professor Yu Jie of the School of Materials Science and Engineering of Harbin Institute of Technology has made significant progress in graphene material growth technology, and the research results were published in the internationally renowned materials journal "Advanced Materials", and the paper is "Thermochemical vapor deposition growth of three-dimensional graphene fibers"
.
It is understood that graphene has many superior properties due to its unique monoatomic layer structure, which has attracted wide attention in recent years and has great
application prospects.
However, because graphene is flaky, it is easy to agglomerate during application, thereby losing its superior properties derived from the monoatomic layer structure, and the preparation of three-dimensional graphene with a three-dimensional network structure is an effective way
to solve this problem.
Under the guidance of his supervisor Yu Jie, Zeng Jie, a doctoral student in the School of Materials Science and Engineering, successfully realized the vertical directional growth of graphene sheets on the surface of electrospun nanocarbon fibers by thermochemical vapor deposition (CVD), and obtained a new type of three-dimensional graphene continuous fiber material, the main structure and performance indicators are greatly improved
than the existing three-dimensional graphene materials.
This work pioneered a three-dimensional graphene continuous fiber material, broke through the problem that thermal CVD cannot grow vertical graphene, found a rapid growth catalytic pyrolysis method, and carried out large-size block material growth demonstration, eliminating the main obstacle to the large-scale application of vertical graphene, and it is expected to quickly achieve large-scale production
.
It is reported that the research group has successfully extended this technology to other substrates to grow vertical graphene, such as carbon fiber, oxide/carbide/nitride fiber, carbon foam, carbon black, silicon particles, etc.
, which can be widely used in thermal/electrical/high-strength composite materials, flexible conductors, electromagnetic shielding, sound absorption, energy storage, catalysis, adsorption purification and other fields, demonstrating great application potential
.
The achievement has applied for Chinese invention patent and PCT patent right
