Embodiment 1
[0049] Preparation and application of a two-dimensional polymer film based on discotic triboron core molecules such as figure 1 , 2 , 5, wherein the preparation includes the synthesis of 3(NHN), 3B(NF) 2 The synthesis of and the preparation of 2D-3BN, the structure of 3(NHN) is shown in formula (I):
[0050] Wherein, in the present embodiment R1 is hexyl, 3B(NF) 2 The structure of is shown in formula (II):
[0051] Among them, R2 is the same as R1;
[0052] Applications include the preparation of semi-solid gel electrolytes and the preparation of 2D-3BN@MSCs, each step is as follows:
[0053] (1) Synthesis of 6,12,18-tris(hexylamine)-5,11,17-triazatrinaphthalene (3(NHN))
[0054] 6,12,18-trichloro-5,11,17-triazatrinaphthalene (1.0 equivalent) was dissolved in n-hexylamine ( figure 2 R0 in the mixture is hexyl) at a temperature of 132-135° C., stirred and refluxed at a speed of 20-40 r / min for 3 days. After cooling for 1 h to room temperature, the mixture was precip...
Embodiment 2
[0065] The 2D-3BN prepared in Example 1 is used to prepare 2D-3BN-3@MSCs, and the preparation route is also as Figure 5 As shown, the specific steps are as follows:
[0066] (i) Preparation of semi-solid gel electrolyte
[0067] First, dissolve 3g of polyvinyl alcohol (PVA) in 30mL of deionized water, and heat it to 98°C on a stirring table at a speed of 50-60r / min to fully dissolve the polyvinyl alcohol. After the PVA is completely dissolved, then The mass concentration of 3g diluted is 0.1mg mL -1 The LiCl solution was slowly added dropwise to the polyvinyl alcohol solution, and continued stirring to dissolve it completely. After the solution was cooled to room temperature for 2 hours, a semi-solid gel PVA-LiCl electrolyte could be obtained.
[0068] (ii) Preparation of 2D-3BN-3@MSCs
[0069] 2D-3BN-3@MSCs are prepared by simple magnetron sputtering coating and laser etching technology, the specific operation steps are as follows: first, put the 3 layers of completely drie...
