Problems solved by technology

[0004] (1) The film preparation under the existing technical conditions is either single homogeneous or layered, but these two structures have defects under the existing technical conditions. The defect of the former lies in the homogeneous structure. For The requirements for equipment and methods are extremely high, and manual assistance is required in the process of processing, and manual auxiliary processing is easy to leave marks on the surface of the film and destroy the integrity of the film surface, while the latter has poor mechanical properties due to poor continuity. And it can't meet the demand of homogeneity;
[0005] (2) Operation without an integrated structure under the existing technical conditions will easily lead to stagnation in the process of layering processing, resulting in damage to the membrane structure and poor continuity

Abstract

The invention discloses a device and method for producing a graphene perovskite nano-film. The device comprises a pedestal, a base plate and a muffle furnace are respectively fixedly mounted at two ends of the upper surface of the pedestal, a longitudinal support rod is fixedly mounted on the base plate, the longitudinal support rod is fixedly provided with three rotating shafts, the rotating shaft at the top is provided with a dropping pipette through a first clamping arm, the two rotating shafts at the bottom are respectively provided with a sleeve circular ring and a protective cover through second clamping arms, a rotating smearing plate is arranged on the sleeve circular ring, the bottom of the rotating smearing plate is movably connected with a rotation shaft through a rotating shaftbuckle, and the other end of the rotation shaft is connected with a rotating motor. The finished graphene perovskite nano-film is obtained through carrier plate pretreatment, graphene suspension preparation and smearing fixing. The film has good mechanical properties and a flat surface; and the whole process is continuous, a layered membrane structure is continuous, so the film has good continuity of the film, thereby the layered structure has the characteristics of a homogeneous membrane.

Description

technical field [0001] The invention relates to the technical field of nanocrystal preparation, in particular to a preparation device and method for a graphene perovskite nanofilm. Background technique [0002] Perovskite is an important mineral. Because of its special physical structure and good physical and chemical properties, it has more and more applications in various aspects, and the related research is also deepening. However, most of the research on perovskite is limited to powder, and the photocatalytic activity of its thin film is rarely studied. Since thin-film catalysis has no secondary pollution and is easy to recycle and reuse, making perovskite-type composite oxides into thin-film materials can promote its application in electrocatalysis, photocatalysis, etc. Graphene, which has been successfully discovered and synthesized in recent years, is a nanomaterial with two-dimensional carbonaceous planes, and has become a research hotspot in this field. With its u...
