Problems solved by technology

[0003] There are currently two problems in the preparation and performance research of graphene-enhanced aluminum matrix composites. When graphene is added to the aluminum matrix, how to improve the dispersion of graphene; the wettability between graphene and the matrix is ​​poor
These two problems prevent graphene from playing a greater role in the aluminum matrix, so it is difficult to obtain high-quality graphene-reinforced aluminum matrix composites
