Abstract

The invention relates to a transparent conductive ionic gel composition capable of realizing 3D printing as well as preparation and application of the transparent conductive ionic gel composition. Theconductive ionic gel is prepared from a composition and comprises polyurethane urea with a linear structure, ionic liquid and an organic solvent, and the ionic liquid accounts for 5%-80% of the massfraction of the polyurethane urea with the linear structure. Ionic conductive gels of different structures can be constructed through direct writing 3D printing, and the conductive ionic gel has goodmechanical strength (the stress is as high as 2.55 MPa, and the strain is as high as 2200%), high transparency (as high as 98%), high conductivity (as high as 3.18 S.m < 1 >) and a wide working temperature range. The conductive ionic gel has excellent electromechanical properties, so that the conductive ionic gel has good strain induction capability, can be used for preparing strain sensors and isused for monitoring various motions of a human body.

Description

technical field

[0001] The invention relates to the field of transparent and flexible conductive gels, in particular to a 3D printable and transparent conductive ion gel and its preparation and application. Background technique

[0002] With the rise of wearable devices, the demand and research of flexible sensors are increasing, which need to have strong stretchability, ductility, bendability and durability, low power consumption and quality, if it is skin-friendly Non-toxic sensors must also be biocompatible. Flexible sensors can be used in human health monitoring, human motion monitoring, human-computer interaction and soft robotics, etc. Traditional flexible and stretchable devices are based on a mixture of conductive fillers and elastomers, which have problems such as mismatching of mechanical properties, poor interfacial compatibility, and poor transparency, which limit their many potential applications. Stretchable conductive hydrogels have attracted extensive atten...
