| 摘 要： | 借鉴自然界生物矿化的形成机理,利用蒸发诱导自组装(EISA)的方法,以十六烷基三甲基溴化铵(CTAB)为结构导向剂,正硅酸乙酯(TEOS)为硅源,通过浸渍提拉在普通玻璃片上制备出高有序度、三维六方结构的介孔氧化硅薄膜,通过XRD、TEM、低温N2吸附/脱附等方法对薄膜进行了表征,并初步讨论了形成三维六方结构的机理.

| Abstract: | Imitating the mechanism of biomineralization,highly oriented 3D-hexagonal(P6_3/mmc) mesoporous silica thin films were prepared by evaporation-induced self-assembly(EISA) process using cetyltrimethyl ammonium bromide(CTAB) as the structure-directing agents and tetraethyl orthosilicate (TEOS) as the silica source.The films were deposited on glass substrates by dip-coating method.Their structure were characterized by small-angle X-ray diffraction(XRD),transmission electron microscopy(TEM) and nitrogen adsorption.A possible pathway has been proposed for the formation of 3D-hexagonal mesoporous silica thin films. |
