Embodiment 1
[0051] Take 5g of sodium montmorillonite, add it to 20mL dimethyl sulfoxide (DMSO), react at 55°C for 2 hours, centrifuge to remove the mother liquor, then wash with ethanol and deionized water three times, and dry at 70°C. about 8 hours. Weigh 12.5 mg of montmorillonite / DMSO intercalate, add 10 mL of deionized water, and stir magnetically at room temperature for 1 hour; measure 50 μL of Si69, add it to 100 mL of ethanol, and magnetically stir at room temperature for 1 hour, then mix the two solutions Mix and stir magnetically at 65°C for 5 hours. After cooling the solution, the mother liquor was removed by centrifugation, washed repeatedly with deionized water for 3 times, and then ultrasonicated for 30 minutes to obtain a suspension. Vacuum filtration for 2-3 hours to obtain a montmorillonite film, dried at room temperature for 24 hours and then stored.
