[0042] 1. Sample preparation
[0043] (1) The preparation of embodiment 1 sample is carried out according to following steps and technology:
[0044] Step 1: Dissolve 1.0 g of cetyltrimethylammonium bromide in 500 mL of distilled water, then add 4 mL of NaOH (2M) into the solution. Gradually raise the temperature to 80Β° C., drop 20 mL of ethyl orthosilicate into the above solution, and continue to stir and react at constant temperature for 4 h. After the end, the solvent was removed by centrifugation, and the obtained precipitate was repeatedly washed with methanol, and dried in vacuum at 60Β° C. for 8 hours to obtain white powder A.
[0045] Step 2: Add 4.0g of powder A and 11.5mL of coupling agent Ξ³-aminopropyltriethoxysilane into 600mL of toluene, ultrasonically oscillate for 10min, then gradually raise the temperature to reflux, and continue stirring for 20h. After the reaction, the solvent was removed by centrifugation, an...

[0067] 1. Sample preparation
[0068] (1) The preparation of embodiment 2 sample is carried out according to following steps and technology:
[0069] The 1st~5 step technology are with embodiment 1.
[0070] Step 6: Add powder E, plasticizer propylene carbonate, and lithium perchlorate into the polymethyl methacrylate matrix, and prepare a composite gel-type polymer electrolyte membrane through a solution-casting process. The distribution ratio of each component: the mass ratio of the plasticizer to the matrix is ββ30:100, the mass ratio of the lithium salt to the matrix is ββ50:100, and the mass ratio of the powder E to the matrix is ββ10:100. Preparation process: first dissolve the polymer matrix in THF to prepare a uniform polymer solution I (concentration is 40% by mass); then add plasticizer, lithium salt and powder E in THF in proportion, and use ultrasound to It was uniformly dispersed, and the solvent was further remov...
