| 摘要 |
The present invention relates to the field of material, and in particular to fabrication of disordered porous silicon dioxide materials and the use of fatty alcohol polyoxyethylene ether in such fabrication. Said fatty alcohol polyoxyethylene ether has a formula of RO-(CH2CH2O)n-H is used as an additive for fabricating disordered silicon dioxide porous materials, wherein R is C8-24, n=9-30. As compared with the material fabricated by the existing methods, the silicon dioxide materials fabricated in the present invention have an excellent mono-dispersity, a uniform and adjustable size, a simple fabrication process, a relatively short production cycle, a tendency for mass production, and a wide application field. Furthermore, an inclusion material like nanometer Au, Pt, light-emitting quantum dots, or magnetic particles can be embedded in advance or introduced after preparation of the material, and the surface functional group can be modified, so as to further expand the application field. |
