Abstract

The present invention relates to the preparation process of composite superlattice material with alternate organic and inorganic thin layers, and relates to composite material and functional material. By means of the feature that surfactant can form laminated film in weak alkaline microemulsion, the kinds and concentration of surfactant and inorganic ion in the solution is regulated to realize the direct assembling, synthesis, dispersion and fixing of semiconductor quantum points between laminated surfactant films. The composite material is one regular laminated superlattice structure, has hydrophilic and lipophilic property, and may be used in the preparation of cosmetics, rubber product, etc. to lower the production cost. The composite material has high configuration stability, easy preparation and wide latent application.

Description

[0001] The invention is a new method for preparing a layered superlattice film composite material in a microemulsion, and relates to the fields of composite materials and functional materials. Specifically, it involves the use of the characteristics that surfactants can form multilayer films in microemulsions, and intercalation and synthesis of various functional inorganic nano-quantum dots between films, thereby preparing surfactant films and semiconductor quantum dot particle films alternately. Stacked superlattice materials. Background technique [0002] Self-assembly synthesis is an eye-catching cutting-edge synthesis technology in recent years. The self-assembly system of nanostructures refers to weak and less directional non-covalent bonds, such as hydrogen bonds, van der Waals bonds and weak ionic bonds. Synergy links atoms, ions or molecules together to build an ordered nanostructure. The synergistic effect produced by the presence of a sufficient number of non-covale...
