Abstract

The invention discloses an ionic conductive electrochemical luminescent hydrogel for a luminescent displayer and a preparation method of the ionic conductive electrochemical luminescent hydrogel. Theelectrochemical luminescence hydrogel is a composite electrochemical luminescence hydrogel formed by adsorption of sodium chloride / ruthenium tripyridine chloride / tri-n-propylamine into a three-dimensional network structure of an anionic polyacrylamide hydrogel, specifically, monomer acrylamide, sodium monomer acrylate, cross-linking agent methylene diacrylamide, conductive medium sodium chloride,the electrochemical luminescence system ruthenium tripyridine chloride / tri-n-propylamine, initiator ammonium persulfate and accelerator tetramethyl ethidene diamine are mixed to form a red transparentsolution, and heated at the room temperature or in an oven to form the hydrogel. According to the prepared electrochemical luminescent hydrogel, electrochemical luminescence materials are effectivelyfixed, good light-admitting quality and stretchability of the hydrogel are retained, good conductivity, uniformity and electrochemical luminescence properties are further achieved, the ionic conductive electrochemical luminescent hydrogel can be used in the luminescent displayer and has the advantages that the ionic conductive electrochemical luminescent hydrogel is recyclable, and the trigger voltage is low.

Description

technical field [0001] The invention belongs to the field of composite material synthesis and application, and relates to an ion-conducting electrochemiluminescent hydrogel (NaCl / Ru(bpy) 3 Cl 2 / TPA / APAM hydrogel). Background technique [0002] Due to its high sensitivity, stability and simplicity, electrochemiluminescence has been widely studied in the fields of biological analysis and environmental analysis. Ru(bpy) 3 Cl 2 / TPA, as a classic electrochemiluminescent system, has good recyclability, stability and luminous intensity, and its application in electrochemiluminescent devices can better meet the growing demand for low-cost, disposable or reusable displays. It is expected to become a substitute for organic light-emitting diodes. [0003] Hydrogel is a general term for a class of cross-linked polymers that can swell in water but cannot be dissolved by water. Among them, anionic polyacrylamide (APAM) hydrogel has the characteristics of adsorption, flocculation, a...
