preparation example Construction

[0037] A preparation method of multifunctional organogel, comprising the following steps:

[0038] Step 1: After mixing the solvent and the monomer evenly, add the crosslinking agent, initiator and electrolyte salt respectively to fully dissolve them;

[0039] The second step: the solution prepared in the first step is irradiated with ultraviolet light to make it photocured (in the case of using a photoinitiator) or heated to make it thermally cured (in the case of using a thermal initiator), and the resulting solidification The product is organic gel; when using ultraviolet light for photocuring, the wavelength of ultraviolet light used is 320-400nm, the irradiation power is 30-400W, and the irradiation time is 1-120min; when heating is used for curing, the heating temperature The temperature is 50-100℃, and the heating time is 2-24h.

[0040] It can also include between the first step and the second step: stick the transparent release film on two transparent glass plates, a...

Abstract

The invention discloses a multifunctional organogel, and a preparation method thereof. The raw materials of the multifunctional organogel comprise a solvent, a monomer, a crosslinking agent, an electrolyte salt, and an initiator; the volume ratio of the solvent to the monomer is controlled to be 1:5-5:1; the molar ratio of the crosslinking agent to the monomer is controlled to be 0.05 to 10%; themolar ratio of the initiator to the monomer is controlled to be 0.1 to 10%; and the concentration of the electrolyte salt in a mixed solution of all the raw materials ranges from 0.1 to 5mol / L. The multifunctional organogel possesses high transparency, high stretching performance, and high conductivity; the temperature resistance and the stability are better than those of conventional hydrogel materials; the temperature resistant range is very wide; the elongation at break is 1219% or higher; and the application prospect in the field of flexible electron and flexible machine is promising.

Description

technical field [0001] The invention relates to the field of ion conductors, in particular to a multifunctional organic gel and a preparation method thereof, in particular to a stretchable transparent conductive organic gel and a preparation method thereof. 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, ea...
