Problems solved by technology

[0005] If the existing gels are used for the preparation of sensors, because the 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, their air stability is poor, they are easy to lose water, and their service life is short. In addition, they are easy to react with water and oxygen in the air, and then corrode the metal, resulting in damage to the device, so it is not suitable for the manufacture of sensors.

Abstract

The invention discloses application of a multifunctional organogel in a sensor. The multifunctional organogel comprises raw materials of a solvent, a monomer, a cross-linking agent, an electrolyte salt and an initiator, the volume ratio of the solvent to the monomer ranges from 1:5 to 5:1, the mol ratio of the cross-linking agent to the monomer ranges from 0.05% to 10%, the mol ratio of the initiator to the monomer ranges from 0.1% to 10%, and the concentration of the electrolyte salt in a mixed solution of all raw materials ranges from 0.1 to 5 mol / L. The multifunctional gel is used to manufacture the sensor by using the characteristic that the multifunctional gel does not corrode metal and is high in weather resistance, and a resistive sensor as well as a double electric layer capacitivesensor can be manufactured.

Description

technical field [0001] The invention relates to the field of ion conductors, in particular to the application of a multifunctional organic gel in sensors. 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 is difficult...
