Novel RGO/MXene composite film and preparation method thereof

The invention discloses a novel RGO/MXene composite film and a preparation method thereof, and the method comprises the following steps: carrying out reduction processing on GO through DA to prepare RGO; stripping MAX by using a LiF and HCl mixed solution to obtain a two-dimensional MXene material with a clear lamellar structure; ultrasonically mixing an MXene dispersion solution and an RGO dispersion solution, constructing the RGO/MXene composite film on a PVDF film substrate in a vacuum filtration manner, and applying the RGO/MXene composite film to processing of industrial wastewater. According to the method, the synergistic film-forming mechanism and the separation mechanism of the RGO and the MXene are explored in detail, and some reference significance is provided for further widening the application range of the MXene and developing and constructing more novel high-performance film materials. From the perspective of improvement of the structure of the film material, the processing efficiency and the re
