Abstract

The invention provides a method for preparing a transparent fluorescent ultra-thin film composite material by using a layered vermiculite material and an organic fluorescent molecular material. The transparent fluorescent ultra-thin film composite material is prepared through a supramolecular assembly method, so that the prepared organic-inorganic fluorescent ultra-thin film composite material overcomes the defects of a pure organic material and a pure inorganic material and has the advantages of both, assembly of anions and anion bodies is achieved, and the prepared fluorescent composite material has a longer fluorescent service life, has the advantages of transparency and solidification and has very high promotion and application value.

Description

technical field [0001] The invention relates to a preparation method of a fluorescent material, in particular to a preparation method of a vermiculite fluorescent film composite material, and belongs to the technical field of inorganic non-metallic mineral material processing. Background technique [0002] Supramolecular assembly is defined as a multi-molecular group composed of non-covalent bonds. It can be as simple as two molecules. They can be spherical, rod-shaped or sheet-shaped samples. The purpose of studying supramolecular assembly is to A series of new materials have been obtained. Most of the building blocks studied by supramolecular assembly focus on the molecular and nanoscale, or the assembly between micron and micron-scale objects, etc., which can effectively control the performance of new materials and achieve a leap in product quality. [0003] Vermiculite is one of the non-metallic minerals with good resource prospects and potential advantages in my country...
