| titleOfInvention | Preparation method of ultrahigh-porosity porous silicon dioxide |
| abstract | The invention belongs to the technical field of materials, and particularly relates to a preparation method of ultra-light porous silicon dioxide with ultra-high porosity. The invention adopts the prepolymer of the organic silicon as the stabilizer of the water-in-oil emulsion, and the prepolymer of the organic silicon can be hydrolyzed to generate hydroxyl with hydroxyl after being contacted with water on an oil-water interfaceInterface activity and further condensation to generate silicon-oxygen-silicon bonds; after the organic silicon precursor is hydrolyzed and condensed, a porous framework structure is formed on an oil-water interface, then the oil phase and the water phase are simultaneously removed, and a silicon dioxide framework on the interface is left, so that the porous silicon dioxide material with ultrahigh porosity can be obtained. The method has simple operation process, the porosity of the obtained porous material can reach 99 percent, and the specific surface area can reach 755 m 2 /g。 |
