Graphene is a two-dimensional crystal. Ordinary graphite is formed by stacking planar carbon atom layers arranged in a honeycomb shape. The interlayer force of graphite is weak, and it is easy to peel off each other to form graphite flakes. When the graphite flake is peeled off into a single layer, this single layer with only one carbon atom thickness is graphene.
The latest discovery is the most effective way to prevent corrosion. Commonly used polymer coatings are easy to be scratched, which reduces the protective performance; Graphene, as a protective film, significantly delays the corrosion rate of metals, making it stronger and more resistant to damage.
Graphene is not only a new star in the electronics industry, but also has an infinite future in traditional industries. Its application direction: marine corrosion protection, metal corrosion protection, heavy corrosion protection and other fields. Graphene has good thermal and electrical conductivity.
The flexible graphene heat dissipation film developed and produced by graphene can help existing laptops, smart phones and LED display screens. Graphene can greatly improve the heat dissipation performance.
The role of graphene
It has excellent optical, electrical and mechanical properties, and has important application prospects in the fields of material science, micro-nano processing, energy, biomedicine and drug delivery, and is considered as a revolutionary material in the future. Physicists Andre Geim and Konstantin Novoselov of Manchester University in England won the 20 10 Nobel Prize in Physics for separating graphene from graphite.
