Among the many materials available, only a very small subset of materials had the so-called "subversive genes", and graphene was one of them. As one of the most popular materials, it could be combined with almost any other material.
At least that was how it was in theory.
To a large extent, what restricted the development of modern materials technology wasn't the lack of innovative ideas. It was to find a way to realize the ideas.
With the current technology available, it would be almost impossible to achieve a composite of silver nanoparticles and graphene with a particle diameter of 1-5 nm.
Whether it was a laboratory preparation method or a developed industry technology, Lu Zhou and Yang Xu couldn't think of any good methods. After some discussion, the two eventually reached a research consensus.
