Examples
Embodiment 1
[0022] (1) Mix 60 mg PEO- b - PMMA dissolved in 9 g tetrahydrofuran. Then 3 g of 2M aqueous HCl was added to obtain a clear and transparent solution. Then add 0.3-0.6 g of tetraethyl orthosilicate and stir evenly.
[0023] (2) Volatilize the clear solution in the above steps under normal pressure at 25°C.
[0024] (3) With the volatilization of the solvent, the solution transitions from colorless and transparent to light blue, then white, and finally a large amount of white precipitate. The precipitate was separated by centrifugation or filtration, and washed 2-3 times with distilled water. Dry at 60°C.
[0025] (4) Calcinate the white solid obtained in the previous step at 550 °C for 5 h in a muffle furnace.
Embodiment 2
[0027] (1) Mix 60 mg PEO- b - PMMA dissolved in 9 g tetrahydrofuran. Then 3 g of 2M aqueous HCl was added to obtain a clear and transparent solution. Then add 0.3-0.6 g of 1,2-bis(trimethoxysilyl)ethane and stir well.
[0028] (2) Volatilize the clear solution in the above steps under normal pressure at 25°C.
[0029] (3) With the volatilization of the solvent, the solution transitions from colorless and transparent to light blue, then white, and finally a large amount of white precipitate. The precipitate was separated by centrifugation or filtration, and washed 2-3 times with distilled water. Dry at 60°C.
[0030] (4) Calcinate the white solid obtained in the previous step at 550 °C for 5 h in a muffle furnace.
Embodiment 3
[0032] (1) Mix 60 mg PEO- b -PS was dissolved in 9 g THF. Then 3 g of 2M aqueous HCl was added to obtain a clear and transparent solution. Then add 0.3-0.6 g of methyl orthosilicate and stir evenly.
[0033] (2) Volatilize the clear solution in the above steps under normal pressure at 25°C.
[0034] (3) With the volatilization of the solvent, the solution transitions from colorless and transparent to light blue, then white, and finally a large amount of white precipitate. The precipitate was separated by centrifugation or filtration, and washed 2-3 times with distilled water. Dry at 60°C.
[0035] (4) Calcinate the white solid obtained in the previous step at 550 °C for 5 h in a muffle furnace.
