(1) The preparation process of the gel electric actuating membrane solution comprises the following steps:
starting the magnetic stirrer, setting the temperature at 50 ℃ and the stirring speed at 50% of the maximum stirring speed, placing a beaker filled with 50ml of distilled water in a water bath environment on the magnetic stirrer, and heating to 50 ℃. 1.25g of sodium alginate powder was weighed out using an analytical balance and slowly dissolved in 50ml of distilled water at 50 ℃. After the sodium alginate is completely dissolved, 4ml of ionic liquid [ EMIm ] is dripped]BF 4 And heating and stirring in water bath at 50 deg.C for 15min. Then 0.2g of sodium dodecyl sulfate is added into the solution evenly, and the solution is heated and stirred continuously until the solution is heated and stirredAnd completely dissolving. Measuring 3ml of glycerol with a disposable rubber-tipped dropper, slowly dripping into the above solution, and continuously heating and stirring for 20min to ensure that the humectant is uniformly mixed. And then pouring a certain amount of water into an ultrasonic cleaning machine, setting the defoaming time to be 10min, placing the prepared solution in the ultrasonic cleaning machine for vibration defoaming, and repeating for 4-5 cycles. The solution after vibration defoaming treatment was slowly and uniformly poured into a horizontal glass mold 50mm × 50mm × 5mm using a glass rod, and then allowed to stand for 20min to ensure the solution level.
(2) The preparation process of the porous gel electric actuating membrane comprises the following steps:
the freeze-casting machine was started and the gel electroactive film solution after standing was placed in a tray, and a temperature sensor was placed next to it. And then placing the freezing molding frame in a cold trap, tightly covering a sealed glass cover above the freezing molding frame, setting the refrigerating function of a freezing casting machine to be 60 ℃ below zero, and freezing the gel electric actuating membrane solution in the cold trap for 7 hours. After the freezing forming is finished, the frozen and pre-formed ice-shaped gel electric actuating membrane is quickly taken out from the freezing chamber and is placed on a bracket above the freezing chamber, the bracket is a casting frame, a glass cover is immediately covered, and a vacuum pump is started to form a negative pressure vacuum internal environment. In addition, the refrigeration function of whole process, to keep the open mode all the time, then cryogenic cold trap catches and adsorbs the vapor that the sublimation came out by oneself. After 24 hours, the semi-finished product of the porous gel electric actuating membrane is prepared, and the drain valve is opened to drain water.
(3) The processing process of graphene composite strengthening and toughening comprises the following steps:
preheating at 50 deg.C, vacuum drying for 30min, placing the other side in a culture dish container of 12cm, and placing porous gel electric-actuated membrane semi-finished product. With reference to fig. 2 and 3, 50ml of the graphene aqueous dispersion after the second dispersion is extracted by a needle tube and is slowly and uniformly cast into a culture dish along a glass rod until the gel electroactive film semi-finished product is immersed. Then horizontally placing the culture dish in a vacuum constant temperature drying oven, setting the temperature at 50 ℃, the vacuum degree at-0.090 MPa, standing for 4h, closing a switch of the drying oven to carry out natural cooling and drying to obtain a finished product of the porous gel electric actuating membrane, wherein the casting thickness of the finished product is 0.8-1.0mm.
The specific working principle is as follows:
as can be seen from FIG. 4, the ionic liquid [ EMIm]BF 4 In sodium alginate solution, all ionizes to anions [ BF ] 4 ] - With cations [ EMIm] + . Part of anions and cations are strongly coordinated with hydroxyl in sodium alginate molecules through synergistic action to form a large number of hydrogen bonds, so that the sodium alginate molecules are further self-wound through the hydrogen bonds to form a gel polymer, and the plasticizing effect is achieved, so that the internal resistance is reduced, the specific capacitance is improved, and the elastic modulus is reduced. Meanwhile, the other part of the remaining anions and cations are retained in a three-dimensional network structure in the gel film, can move freely and are always in a disordered free state. Under the action of an external direct current electric field, the gel electric actuating membrane can generate directional migration, and the large deformation and the improvement of the response speed of the gel electric actuating membrane are facilitated.
Furthermore, the novel graphene composite toughened porous gel electric actuating membrane has a unique electric actuating mechanism, namely, the novel graphene composite toughened porous gel electric actuating membrane can show long-term practical performance and has stable electrochemical characteristics to water and air under the conditions of open air and dry non-external solvents. Specifically, under the action of an external direct current electric field, free cations in the electric actuating membrane can directionally migrate to the negative electrode interface of the electric actuating membrane; meanwhile, the free anions are continuously enriched to the interface of the positive terminal. When the accumulation amount of the charged ions is enough, the volume of the negative electrode side is expanded and is larger than that of the positive electrode side (a serious volume difference is generated) because the radius of the positive ions is obviously larger than that of the negative ions, and the actuation deflection effect of the gel electric actuation film is further promoted because the electrostatic repulsion action exists among the same-polarity ions.
While the present invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof as defined in the appended claims.
