preparation example Construction

[0037] A preparation method of multifunctional organic gel includes the following steps:

[0038] The first step: After uniformly mixing the solvent and monomer, add the crosslinking agent, initiator and electrolyte salt to make them fully dissolved;

[0039] The second step: irradiate the solution prepared in the first step under ultraviolet light to make it photocurable (in the case of using a photoinitiator) or heat it to be thermally cured (in the case of using a thermal initiator), and the resulting cured The product is an organic gel; when UV light is used for photocuring, the UV wavelength 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 It is 50-100℃, and the heating time is 2-24h.

[0040] The first step and the second step can also include: pressing the transparent release film tightly on two transparent glass plates, and then fixing the mold between the release film; in the ...

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 received widespread attention from all over the world in recent years and have been rapidly developed. With the increasing demand for flexible wearable devices and soft machines, some high-performance ion conductors with unique functions have gradually been favored by people. Different from electronic conductors, ionic conductors use ions as charge carriers to transmit signals, and realize many functions that are difficult for electronic conductors, thus making various modern technologies possible, such as fuel cells, alkaline batteries, electrochemical transistors, and sensors. Hydrogel is the most widely studied ion conductor at this stage. It has the characteris...
