Mass production of graphene is not easy. But making small blocks of graphene is doable in a few ways. [Robert Murray-Smith] decided to produce”Flash graphene.” This requires a large capacitor bank that is moderately expensive, so he decided to demonstrate a different technique he read about using an ordinary laser cutter. Check it out in the video below.
We’re a little disappointed that he didn’t actually do any graphene this time. However, he used other methods in other videos Create some form of graphene. In fact, he has many similar videos Quite a way As well as applications with concrete, capacitors and Further. We understand that this method does not create monolayer graphene, but actually creates a „foam” of graphene with interesting properties. [Robert] Recent papers talk about using this method to grow graphene on materials other than Kapton tape.
If you decide you want to give it a try, we’d love to see your results. [James Tour] Here is a video from Rice University Laser-induced graphene It might help you too. We have seen [Zachary Tong] Using this method, as well. The flash process is also interesting because it appears to be more scalable compared to other methods.
