Embodiment 1
[0038] In this Example 1, a preparation method of the above-mentioned liquid crystalline copolymer with electric storage properties, 0.5 g of monomer X, 0.8 g of monomer Y, 0.02 g of azobisisobutyronitrile and cyclohexanone 2 Add mL into a polymerization tube, react in an oxygen-free environment at 80°C for 12 h to 20 h, then pour the reaction product into methanol to precipitate a solid, and dry to obtain the copolymer. Wherein, azobisisobutyronitrile is used as a catalyst for the polymerization reaction; cyclohexanone is used as a solvent, and any one or more of toluene, dimethylformamide or dichloroethane can also be used to replace; an oxygen-free environment can be passed This is achieved by introducing an inert gas into the reaction vessel, and the inert gas that can be used includes any one or more of nitrogen, argon, and helium.
[0039] In this example 1, monomer X can be purchased from the market, and can also be prepared by the following method: the parts mentioned ...
Embodiment 2
[0043] An electric storage device using the liquid crystalline copolymer with electric storage properties obtained in Example 1, such as image 3 As shown, it includes a first electrode layer 1, an active layer 2 and a second electrode layer 3 from bottom to top, wherein the active layer 2 is the copolymer obtained in Example 1 with electrical storage properties. In this embodiment 2, the thickness of the active layer 2 is 100 nm to 200 nm; the first electrode layer 1 is conductive glass, the second electrode layer 3 is a metal electrode, further, the second electrode layer 3 is a magnesium electrode, silver electrode, calcium electrode or aluminum electrode.
Embodiment 3
[0045] A method for preparing the electrical storage device of Example 2, using ITO glass as the first electrode layer 1, using an organic solvent to ultrasonically clean the ITO glass, and drying to remove the organic solvent. In this Example 3, chloroform, Acetone and isopropanol were used to ultrasonically clean the ITO glass in turn; at room temperature, the liquid crystal copolymer with electrical storage properties prepared in Example 1 was dissolved in chloroform, and the configuration was 10 mg / mL-20 mg / mL Stir the solution at a stirring speed of 200 rpm to 1200 rpm for 6 h to 10 h to ensure that the liquid crystalline copolymer with electrical storage properties is fully dissolved; the prepared solution is stirred at a speed of 600 rpm to 4000 rpm Spin coating is on one side of ITO glass, forms the active layer 2 that thickness is 150 nm, and in present embodiment 3, spin-coating rotating speed is preferably 1500 rpm; ×10 -4 A 100 nm aluminum electrode is plated on ...
