Method and device for preparing porous ionic gel

The invention discloses a porous ionic gel preparation method and device, the device comprises a bubble generation device, a mechanical movement device and a curing and drying system, the bubble generation device comprises a gas pump and a gas pipeline, nitrogen is controlled to be output by the gas pump, and a prepolymer solution is guided through the gas pipeline; the mechanical movement device comprises a crank sliding block mechanism and a motor, the motor controls rotation of a crank, up-down reciprocating motion of a sliding block is achieved, a gas pipeline fixed to the sliding block is driven to do periodic motion in the solution, and therefore bubbles with the controllable size are generated; the curing system comprises an ultraviolet irradiation box and a constant-temperature and constant-humidity box, an ionic gel prepolymer solution full of bubbles is subjected to illumination for one minute in the ultraviolet irradiation box, then the porous framework is preliminarily shaped, and then the porous
