The invention relates to the field of manufacturing of film materials and devices, in particular to rotary spraying film making equipment. The equipment can rapidly prepare a film material of a directional orderly designable microstructure from dispersion liquid or solutions of different materials. A core component of the equipment is composed of four basic parts comprising a rotary roller die, aliquid spraying assembly, a temperature control assembly and a safety protection assembly. According to the equipment, a solution or dispersion liquid is used as a raw material, large-area rapid preparation of a single-ingredient film or a composite film material with two or more ingredients of two-dimensional materials, organic polymer materials and other organic and inorganic nanometer materialscan be achieved, and the obtained film is highly orderly in microstructure, has designability, and can be used for research, development and industrial production of high-performance film materials.
