Graphene is a relatively special new material, forming a single-layer two-dimensional honeycomb lattice structure composed of closely packed carbon atoms. With its exceptional optical, electrical, and mechanical properties, many scientists believe that graphene will play a significant role in materials science, energy, biomedicine, and drug delivery, considering it a revolutionary material for the future. As early as 2004, physicists Andre Geim and Konstantin Novoselov from the University of Manchester in the UK used a micromechanical exfoliation method in their experiments. They attached graphite flakes separated from graphite onto adhesive tape and repeatedly tore the tape apart, splitting the flakes into thinner pieces. Through this process, they successfully obtained an extremely thin layer of graphene composed of carbon atoms. For this groundbreaking work, they were awarded the Nobel Prize in Physics in 2010. Inspired by their method, subsequent researchers often adopted this exfoliation technique to extract graphene, eventually developing various production methods such as oxidation-reduction and SiC epitaxial growth. This demonstrates the high level of attention researchers have given to graphene. Given its rich physical and chemical properties, graphene is expected to become a next-generation material in various applications. To expand its application fields and develop more advanced preparation techniques, the pace of industrial application has been rapid from the outset. Building on established research achievements, graphene has played a pioneering role in areas such as mobile devices, aerospace, and new energy batteries. What specific characteristics make graphene so highly regarded by researchers? From a physical perspective, due to its unique internal structure, graphene exhibits excellent electrical conductivity and optical properties. It also possesses notable electronic effects and thermal properties, with an exceptionally high thermal conductivity coefficient. Combined with its outstanding optical characteristics, graphene plays an indispensable role in physics research and the manufacturing of large-scale equipment. From a chemical perspective, its chemical properties are similar to those of graphite, allowing it to adsorb or desorb various atoms and molecules. When combined with other substances, it often forms new compounds. However, this does not mean graphene lacks stability. On the contrary, its internal structure is highly stable, with carbon atoms naturally shielding against certain external disturbances, minimizing their impact. Of course, graphene's unique characteristics extend far beyond these, which explains why so many researchers are eager to experiment with and develop it. However, why hasn't graphene achieved broader development? The reason is closely related to its inherent properties. Nearly 70% of the world's graphene patents come from China, the country with the largest graphite reserves in the world.
