Researchers develop ultra-high speed laser technology for large-scale production of graphene materials

Researchers at the AIMEN Technology Center in Spain recently demonstrated new technology for ultra-high speed laser processing of graphene materials that makes it possible to produce graphene on a large scale. Relevant research papers published in the "Applied Physics Letters". Graphene has unique electronic and optical properties and its industrial production may bring a new era of fast, reliable, low-power communications and information processing. However, there are currently two major problems that hinder the widespread use of graphene products: firstly, there is no mature technology in industrial production for mass production of graphene with special properties; secondly, the conventional solid state technology for silicon-based processing does not apply to Polymeric material graphene processing. Researchers at AIMEN showcased new technologies that induce changes in the chemical lattice of graphene through short laser pulses. The duration of a single laser pulse lasts only a few seconds and polar molecules in graphene produce a constant oscillation like water waves. The researchers found that during the oscillation, external molecules or desired compounds can be added to the graphene by cutting the graphene lattice. The spot of the laser light can be concentrated in a square with a side length of 1 μm or in a smaller area so that the entire addition process can be controlled with high precision. In the process of new technology, a large number of graphene can be cut under high-speed and high-precision conditions, which opens up a new way for the extensive application of graphene. Using this technique, graphene micron-sized will be more than 1 meter per second. In addition, the technology also shows the chemical process of controlling heat absorption by adjusting laser changes. At low energy output, multiphoton absorption plays a dominant role in the chemical reaction between carbon and atmospheric molecules, giving new optical properties to graphene, which also helps to make it more functional by altering the optical potential of graphene The The researchers said the performance of this technology in the industrial area needs to be further verified. Current research is based on industrial production considerations with the goal of studying in depth the feasibility of graphene in chemical and physical changes while attempting to control its industrial production with electronic equipment programs.
