Problems solved by technology

But there are still many problems to be solved: 1) the graphene used in the experiment often has defects, which seriously affect the performance of graphene; 2) the wettability between graphene and some metal substrates is not good, which makes the interface of composite materials The bonding strength is not good, and sometimes the interface will react to form other phases with poor performance; 3) Graphene is easy to agglomerate in the metal matrix, and its morphology and uniformity are difficult to control; 4) Graphene and metal The strengthening mechanism between the matrix is ​​not clear, the experimental process is time-consuming and labor-intensive, and the experimental results are accidental
