Embodiment 1
[0044] This embodiment includes the following specific steps:
[0045] S1. Preparation of organosilicon electrolyte matrix: in a 250mL dry four-necked flask with a thermometer, a condenser, and a stirrer fed with argon at the same time, 0.25mol of allyl polyethylene glycol (molecular weight 400) and 0.3mol of HSi (OC 2 H 5 ) 3 Add to the bottle, stir and heat up to 60 o C, drop 0.4mL of chloroplatinic acid solution, continue to react for 2h and then drop to room temperature and then discharge, remove unreacted HSi (OC) by vacuum distillation 2 H 5 ) 3 , to obtain the hydrosilylation product. Mix 0.1 mol of the hydrosilylation product, 0.1 mol of triethylamine and 50 mL of tetrahydrofuran, and then add it to a flask with a thermometer, a condenser, a stirrer, and a constant pressure funnel, and dissolve 0.12 mol of methacryloyl chloride in 30 mL of tetrahydrofuran. , pour it into a constant pressure funnel, stir and control the temperature at 50 °C, add it to the flask fo...
