Abstract

The invention discloses a preparation method of a hydrotalcite-based magneto-optical thin film material. The process utilizes metal ion adsorption deposition, obtains a hydrotalcite-based magneto-optical thin film precursor under vacuum conditions, and then uses inert gas washing, ultraviolet curing and other processes A finished film material is obtained. The prepared hydrotalcite-based magneto-optical thin film material has the advantages of simple manufacturing process, uniform and compact texture of the thin film material, superior electrical properties, and good application prospects.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to a method for preparing a hydrotalcite-based magneto-optical film material. Background technique [0002] The layer-by-layer assembly method is an important film-forming technology that assembles different building blocks alternately based on weak interactions to construct ordered composite ultra-thin films. In the past few years, layered double metal hydroxide (also known as hydrotalcite, LDHs) composite functional thin film materials based on layer-by-layer assembly technology have shown important application value in many fields, such as anti-reflection coating, electrochemical Energy storage and conversion, fluorescent sensing, and drug slow / controlled release systems, etc. However, the previous research work was mainly based on electrostatic interactions. The positively charged LDHs nanosheets were assembled with negatively charged polyelectrolytes after peeling off. ...
