Abstract

The invention discloses a composite material based on a melamine cyanuric acid hydrogen bond self-assembly structure, a preparation method and an application. In the invention, the composite material based on the melamine cyanuric acid hydrogen bond self-assembly structure is obtained by mixing the melamine aqueous solution, the metal salt solution and the cyanuric acid aqueous solution, and stirring and reacting. In the preparation method provided by the present invention, the pre-prepared chemical substance melamine capable of self-assembly behavior is mixed with an aqueous solution of cyanuric acid, and the two molecules are assembled together through hydrogen bond forces, and metal salt ions are adsorbed on the surface, and the obtained The metal ion or metal oxide composite material based on hydrogen bond self-assembly structure has a good antibacterial effect. The synthesis condition of the material is mild and convenient, the raw material price is low, and it is easy to be commercially developed. The composite material based on the melamine cyanuric acid hydrogen bond self-assembly structure of the present invention can also be applied to antibacterial in many fields such as environmental protection, construction, medicine, etc., and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of self-assembly synthesis, in particular to a composite material based on a melamine cyanuric acid hydrogen bond self-assembly structure, a preparation method and an application. Background technique [0002] Microorganisms are a general term for all tiny organisms that are difficult for individuals to observe with the naked eye. Microorganisms are an important part of the natural ecosystem. Among the microorganisms in nature, most microorganisms are harmless to humans, some are beneficial to humans, and only a few microorganisms can cause human diseases. However, the harm caused by this small amount of microorganisms cannot be ignored. Pathogenic microorganisms will multiply rapidly under suitable temperature and nutrients, resulting in material deterioration, corruption, mildew, and wound suppuration and infection, which seriously threaten human health. In recent years, microbial disasters have occurred...
