Abstract

The invention discloses a preparation method of diphenylamine sulfonate intercalated hydrotalcite material which belongs to the technical field of preparation of inorganic and organic compound function materials, and application of the material serving as an oxidation-reduction discolored material and an electrochromic material. The technical scheme disclosed by the invention is as follows: the diphenylamine sulfonate intercalated hydrotalcite material which is uniformly dispersed in hydrotalcite layers is obtained by intercalation through a coprecipitation method by adopting a hydrothermal reaction and taking NaOH as an alkaline reagent. The material can fully utilize the space limited range effect of the hydrotalcite layers to immobilize an object, so that the material is used as the oxidation-reduction discolored material and the electrochromic material. The composite material oxidized or reduced is substantially unchanged in structure, and the cyclic voltammetry curve verifies that compared with pure diphenylamine sulfonate, the composite material has good oxidation-reduction reversibility and potential application value in the fields such as the oxidation-reduction discolored material and the electrochromic material.

Description

technical field [0001] The invention belongs to the technical field of preparation of inorganic-organic composite functional materials, and in particular provides a diphenylamine sulfonate intercalation hydrotalcite material, and its application as a redox color-changing material and an electrochromic material. Background technique [0002] Due to its wide application in electrochromic, display, military and other fields, electrochromic materials are considered to be one of the most promising smart materials. Polyaniline conductive polymer is one of the most typical electrochromic materials due to its advantages of easy processing, easy protonic acid doping, and rich color changes. The good stability and film-forming properties of organic / inorganic composite conductive polymer materials make them have great application prospects in electrochromic materials. Sodium diphenylamine sulfonate is a soluble aniline with good redox and water solubility. It is used as a redox indica...
