| titleOfInvention | Silica aerogel microsphere wrapping/releasing oily substances and preparation method thereof |
| abstract | The invention discloses a silicon dioxide aerogel microsphere for wrapping/releasing oily substances and a preparation method thereof, wherein the aerogel is spherical and has a unique composite structure: the spherical shell is compact, the interior is porous, and the barrier property exceeds that of the microcapsule with a core-shell structure. Can wrap oily substances, and the oily substances can be released through micropores and mesopores on the spherical shell under the external stimulation. The preparation method comprises the following steps: 1 synthesizing a polyalkoxy siloxane prepolymer; 2, uniformly mixing the prepolymer, the oily substance and water, and then adding alkali to obtain white emulsion; and 3, separating, washing, concentrating or drying the white emulsion to obtain aerogel microsphere dispersion liquid or aerogel microsphere powder. The preparation of the aerogel and the wrapping of the oily substance are synchronously finished, the method is simple and efficient, the cost is low, the wrapping efficiency is close to 100%, and the wrapping amount can reach 95%. The aerogel microspheres have strong mechanical properties, and the surface and internal hydrophilicity and hydrophobicity can be adjusted. The aerogel microspheres can be widely used in the industries of construction, textile, cosmetics, biomedicine and the like. |
