Researchers from the Moscow State University of Russia's Moscow State University of Technology researched and developed nano-microporous pore-forming technology on the surface of graphene sheets to control the pore size of nano-micropores. The successful development of this technology is the application of graphene Opens up a broader perspective, and the corresponding results appear in the 'Carbon' scholarly journal.
The researchers first theoretically studied the mechanism of nanoporous pore formation on graphene sheets and the relationship between pore size and ion energy on the surface of graphene sheets under accelerated ionization, while experiments using carbon, oxygen, silicon, gold, iodine, xenon, tantalum The ions of different mass elements bombard the graphene sheets under different energies.The energy of ion bombardment can be adjusted and its maximum energy reaches 91 MeV.The experimental results show that the energy of the ions determines the nanopores on the surface of the graphene sheet Of the pore size can be adjusted by the ion bombardment energy to set the size of the nano-pore aperture formed to make it in the 1-4 nm change between the results of the successful study of the specific structure of the graphene material has taken a An important step.
Nowadays, researchers of graphene materials all over the world are studying the methods of graphene controllable modification, including the defects in the structure of graphene to change the microelectronics and conductivity of graphene. Which is magnetic.Russian researchers are improving the process in order to form a controlled distance from the surface of the graphene sheet nano-porous, so that it can be transformed into semiconductor materials used in the microelectronics industry.
Graphene with nano-pores has a very wide range of applications in many fields, for example, can be used for liquid purification, gene sequencing.
