Example Embodiment

[0027] Example 1

[0028] (1) Weigh 9.1 g of double trifluoromethanesulfonyl amide and 7 ml of tetraned diol dimethyl ether in a glass bottle, and the sealing is stirred for 12 h to give a slightly viscous solvation ionic fluid.

[0029] (2) 3 ml of acrylate, 1 ml of ethoxyethoxyethyl escetyl ester, 2 ml of the above prepared solvate ionic fluid and 10 μl of polyethylene glycol diacrylate and 0.04 g of 1-hydroxycyclohexylphenyl group The ketone is added to the small glass bottle to stir, so that it is mixed uniform to obtain an ion gel precursor solution.

[0030] (3) Weighing 0.1 g of ammonium bicarbonate added to 2 mL of the above prepared ion gel precursor solution, stirred for 1 h, making it mixed uniform. Under the transparent mold of a pipette to a tracery film, then place the molded mold on the heater that has been preheated to 100 ° C, adjust the ultraviolet lamp to irradiate power, and select a gradient power irradiation mode. 10W was irradiated for 30 seconds, 5 W for 1 min

Example Embodiment

[0031] Example 2

[0032] (1) Weigh 5.2 g of double trifluoromethane sulfonylimide and 4 ml of tetranedethydrol dimethyl ether in a glass bottle, and the sealing is stirred for 12 h to give a slightly viscous solvate ionic fluid.

[0033] (2) 2.66 mL of propyl acrylate, 1.33 mL of ethoxyethoxyethyl escetyl escetyl ester, 2 ml of the prepared solvated ionic liquid and 10 μL of polyethylene glycol triacrylate and 1.25 g 1 - Hydroxy cyclohexylphenyl ketone is added to the small glass bottle to stir, so that it is mixed uniform to give an ion gel precursor solution.

[0034] (3) Weighing 0.1 g of ammonium bicarbonate added to 2 mL of the above prepared ion gel precursor solution, stirred for 1 h, making it mixed uniform. In the transparent mold of 1 ml to a tracery film with a pipette, the power of the ultraviolet lamp was 10 W under room temperature, and the solution was allowed to obtain a porous ion gel electrode after 2 minutes.

Abstract

The invention discloses a porous solid ionic gel electrode and a preparation method and application thereof. The porous ionic gel electrode is obtained by uniformly mixing an acrylate monomer, a solid ionic salt, a solvated ionic liquid, a cross-linking agent, a photoinitiator and a foaming agent according to a certain proportion, pouring the mixture into a mold and carrying out a photopolymerization reaction under the irradiation of an ultraviolet lamp. Compared with other ionic gel electrodes, the porous ionic gel electrode has higher sensitivity to tension and pressure, and the high sensitivity can be attributed to the porous structure in the ionic gel. The porous ionic gel electrode has application prospects in the fields of multifunctional strain sensors, man-machine interaction and the like.
