High-strength self-repair conductive magnetic electronic skin material and preparation method thereof

Abstract

The invention belongs to the field of biotechnology, and concretely relates to a high-strength self-repair conductive magnetic electronic skin material and a preparation method thereof. The method ischaracterized in that the surface of nano cellulose is coated with polypyrrole, Fe3O4 magnetic particles are immobilized, the materials are added in an agarose aqueous solution for uniform mixing, andthe high-strength self-repair conductive magnetic electronic skin material is prepared. A nano cellulose / polypyrrole / Fe3O4 compound is used so that an agarose hydrogel has intensity, conductivity andmagnetic performance, three disadvantages of low intensity, no conductivity and non magnetic performance of the common agarose hydrogel are improved, and the high-strength self-repair conductive magnetic electronic skin material can be taken as a novel multifunctional electronic skin material.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and in particular relates to a high-strength self-repairing conductive magnetic electronic skin material and a preparation method thereof. Background technique

[0002] Electronic skin, a system that allows robots to generate a sense of touch, has a simple structure and can be processed into various shapes. It can be attached to the surface of the device like clothes, allowing the robot to perceive the location, orientation and hardness of the object. At present, the electronic skin mainly produced has the disadvantages of single function. Therefore, in order to meet the growing industrial needs, it is of great significance to research and develop self-healing, conductive, and magnetic electronic skin materials.
