Abstract

The invention discloses ionic conductive hydrogel and a preparation method and application thereof. The ionic conductive hydrogel comprises gelatin, aldehyde beta-cyclodextrin, polyacrylamide and inorganic salt, and the preparation method comprises the following steps: 1) adding water into the gelatin, the acrylamide and the aldehyde beta-cyclodextrin to prepare a solution, adding a cross-linking agent and the inorganic salt, and stirring for dissolving to obtain a viscous solution; and 2) adding an initiator and a catalyst into the viscous solution, pouring the viscous solution into a mold, and curing to obtain the ionic conductive hydrogel. The ionic conductive hydrogel has the advantages of high conductivity, high mechanical strength, high linear sensitivity, high reliability, bacteriostasis and the like, is simple in preparation process, and has a very good application prospect.

Description

technical field

[0001] The invention relates to the technical field of sensing materials and sensors, in particular to an ion-conductive hydrogel and its preparation method and application. Background technique

[0002] Flexible electronic devices (including circuits, sensors, electrodes, chips, liquid crystal displays, energy storage devices, etc.) The essential. At present, commonly used metal materials, carbon materials, conductive polymers and other materials are usually rigid or have limited stretching ability, and the electrical conductivity of the prepared electronic devices will drop rapidly after being deformed under stretching or bending conditions, making it difficult to Meeting the performance requirements of flexible electronics requires the development of new materials.

[0003] Ionically conductive hydrogel is a semi-solid ion conductor with good mechanical properties and excellent electron and ion transport capabilities, making it an ideal material for buil...
