Problems solved by technology

[0005] Existing gels are difficult to use at extreme temperatures above 60°C or below 0°C. They will lose water and shrink at high temperatures, and will freeze and lose flexibility at low temperatures.
Moreover, they are less air stable, prone to dehydration, and have a shorter service life, so they are not suitable for use as conductive media

Abstract

The invention discloses the application of a multifunctional organic gel as a conductive medium. The preparation raw materials of the multifunctional organic gel comprise a solvent, a monomer, a crosslinking agent, an electrolyte salt and an initiator, the volume ratio of the solvent to the monomer is 1:5 to 5:1, the molar ratio of the crosslinking agent to the monomer is 0.05% to 10%, the molar ratio of the initiator to the monomer is 0.1% to 10%, and the concentration of the electrolyte salt in a mixed solution of all the raw materials is 0.1 mol/L to 5 mol/L. When the organic gel is used asa conductive medium, since the organic gel has good electrical conductivity, a bulb can be lighted when the organic gel is used as a conductive line to energize the bulb, and an LED lamp bead can belighted when the organic gel is used as a conductive substrate to energize the LED lamp bead attached to the conductive substrate.

Description

technical field [0001] The invention relates to the field of ion conductors, in particular to the application of a multifunctional organic gel as a conductive medium. Background technique [0002] Flexible electronic devices have attracted worldwide attention and developed rapidly in recent years. With the increasing demand for flexible wearable devices and soft machines, some high-performance ionic conductors with unique functions are gradually favored by people. Different from electronic conductors, ionic conductors use ions as charge carriers to transmit signals, realizing many functions that are difficult for electronic conductors, thus making various modern technologies possible, such as fuel cells, alkaline batteries, electrochemical transistors, sensors, etc. Hydrogel is the most widely studied ion conductor at this stage, with good transparency, flexibility and conductivity, easy to obtain raw materials, and low price. However, the volatility of water is strong, it ...
