Problems solved by technology

The traditional metal solid interface is stable, but it is difficult to completely separate the prepared material from the interface, and the metal solid interface is expensive. After each film is prepared, it is not easy to carry out the next step of cleaning for repeated use
The liquid interface is generally cheap, and the prepared film is also easy to transfer from the interface, but the liquid interface is unstable and easily disturbed by the outside world.

Abstract

The invention discloses a nitrogen-containing two-dimensional polymer film, the general formula of a structural unit of the film is shown in the specification, or a preparation method of the polymer film comprises the following steps: 1, dissolving a cyanuric chloride monomer in an organic solvent which is insoluble with water to obtain an organic solution; 2, dissolving alkali and amine monomersin water to obtain an alkaline solution, and freezing the alkaline solution; and 3, placing the organic solution on an iced alkaline solution to form an interface, performing standing for 1-60 days atthe icing temperature of the alkaline solution to generate the nitrogen-containing two-dimensional polymer film at the interface, and melting the iced alkaline solution to obtain the nitrogen-containing two-dimensional polymer film. The polymer film is large in transverse dimension and small in thickness, can be used for preparing a field effect transistor, and can also be used as a catalyst forhydrogen production by electro-catalytic water splitting. The preparation method of the polymer film is mild in condition and simple to operate.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a nitrogen-containing two-dimensional polymer film and its preparation method and application. Background technique [0002] Two-dimensional polymer films have properties such as nanoscale thickness, large specific surface area, multiple active centers, and porous structure. These properties make two-dimensional polymer films have important applications in energy storage, electronic information, chemical and environmental protection, and other fields. [0003] At present, two-dimensional polymer films with large lateral areas are mainly prepared by interfacial methods, such interfaces include metal solid interfaces and liquid interfaces (such as toluene). The traditional metal solid interface is stable, but it is difficult to completely separate the prepared material from the interface, and the metal solid interface is expensive. After each film is prepared, it is no...
