I think there are two fatal shortcomings of graphene:

1. High production cost: At present, the production cost of graphene is still relatively high, which limits its wide application.

2. it is difficult to mass-produce: high-quality graphene can be produced in the laboratory, and the production process of graphene needs precise control, but mass production often brings many unpredictable problems.

in the future, with the progress of science and technology, we may find a solution to the problem of graphene production. Its unique properties make it have great application potential in many fields.
