However, there are currently two major problems that have hindered the widespread application of graphene products: first, there is no mature technology in industrial production that can be used for large-scale production of graphene with special properties; second, traditional solid-state technologies for silicon-based processing are not applicable Processing of polymer materials graphene. The researchers showed new technology that induces a change in the chemical lattice of graphene through short green laser pointer pulses.
The duration of a single laser pulse is only a few seconds, and the polar molecules in graphene produce a continuous oscillation like a water wave. Researchers have discovered that during the oscillation process, external molecules or desired compounds can be added to graphene by cutting the graphene lattice.
The laser spot can be concentrated in a square with a side length of 1 micron or a smaller area, so that the entire adding process can be controlled with high precision. In the process of Green Laser Pointer’s new technology, a large amount of graphene can be cut at high speed and high precision, which opens up a new way for the widespread application of graphene.
