Abstract

The invention relates to a preparation method of a high-strength self-repairing polyelectrolyte composite material, and belongs to the technical field of electrolytes. The method takes the polyallylamine hydrochloride as a core material and takes the calcium carbonate as a wall material to prepare the high-strength self-repairing polyelectrolyte composite material. A microcapsule is a spherical carrier, and the contact with potential damage can be realized in an omnibearing and dead-angle-free manner, therefore, the triggering success rate can be improved. In addition, the size of the microcapsule can be designed according to the research requirements to meet different requirements, therefore, a good wrapping means is provided for putting a repairing agent into the microcapsule. The polyallylamine hydrochloride can migrate to a broken part through capillary siphonage to fill a crack, so that the good adhesion is realized, the repair is completed, and the polyelectrolyte has the good self-repairing effect. Moreover, the polyacrylamide hydrochloride can be crosslinked with the sodium polyelectrolyte polystyrene sulfonate to form network combination, so that the mechanical strength and the mechanical property of the self-repaired polyelectrolyte can be enhanced.

Description

technical field [0001] The invention relates to a preparation method of a high-strength self-repairing polyelectrolyte composite material, belonging to the technical field of electrolytes. Background technique [0002] Electrochemical energy storage is now becoming more and more important due to the rapid development of various flexible and wearable electronic devices. It is one of the essential properties for flexible energy storage devices to maintain electrochemical performance under various mechanical strains, especially for bending and shearing strains. This does place more demands on the electrode materials as well as other components in the device such as electrolytes, separators and current collectors, as well as the interfacial bonding between different materials. However, to achieve device flexibility, the unique properties of the materials used for different components should be considered to mitigate the inevitable strain mismatch and delamination during deforma...
