Abstract

The invention belongs to the technical field of sensor materials, and particularly relates to a double-network double-ion conductive transparent electronic skin sensor material and a preparation method thereof. The preparation method of the double-network double-ion conductive transparent electronic skin sensor material comprises the steps that the surface of nanocellulose is wrapped with anthocyanin and then added into a guar gum glycerin aqueous solution for uniform mixing after being absorbed by iron ions; and after borax solution gelation is carried out, the double-network double-ion conductive electronic skin sensor material is prepared. According to the double-network double-ion conductive transparent electronic skin sensor material and the preparation method thereof, a nanocellulose / anthocyanin composite is utilized to enable guar gum hydrogel to have ultra-sensitive electrical conductivity, so that the guar gum hydrogel can be used as a novel electronic skin sensor material.

Description

technical field [0001] The invention relates to a novel transparent electronic skin sensor material, in particular to a double-network dual-ion conductive transparent electronic skin sensor 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 mainly produced electronic skin materials have disadvantages such as poor sensing performance. Therefore, in order to meet the growing needs of new industries, it is of great significance to research and develop electronic skin sensor materials with ultrasensitivity. Contents of the invention [0003] The object of the present invention is to provide a double-network double-ion conductive transparent electronic skin ...
