Description

technical field [0001] The invention relates to the field of films, in particular, the invention relates to an arylated graphene film and a preparation method thereof, an arylated graphene barrier film and a preparation method thereof. Background technique [0002] Quantum dots are three-dimensional clusters with nanoscale size, so they are also called nanodots or nanocrystals. With the rapid development of semiconductor quantum dot synthesis, its advantages such as low cost, high stability, high quantum yield and large-scale production make it considered a solid foundation for further research on many frontier applications. In particular, quantum dots exhibit unique luminescent properties because their diameter is close to the exciton Bohr radius, making them have good application prospects in luminescent materials, displays, and the like. However, due to the poor water vapor and oxygen resistance of quantum dots, it is easily oxidized by oxygen and water vapor in the air,...
