| 摘 要： | 早在几百万年以前,自然界就通过生物矿化过程形成了结构高度有序的有机/无机复合材料,如哺乳动物的牙床、骨骼以及贝壳珍珠层等[1]。随着对天然生物材料生物矿化过程研究的逐渐深入,材料研究者从中得到极为重要的启示:先形成有机物自组装体,无机先驱物在自组装聚集体与溶液相的界面处发生化学反应,在有机自组装体的模板作用下,形成有机/无机复合体,再将有机模板去除即可得到具有一定形状与组织结构的无机材料。这种模仿生物矿化中无机物在有机物调制下形成过程的材料合成,称为仿生合成(biomimetic synthesis)[2]。仿生合成过程中,通过选择有…

| Abstract: | Ordered mesoporous silica inorganic films were prepared in an acid solution at the air-solution interface by the biomimetic synthesis method, during which the hydrolysis of tetraethoxy silane (TEOS) was directed by cetyltrimethyl ammonium bromide (CTAB) supramolecule self-assemblies. The effects of material ratio, pH and sampling time on the qualities of silica films were investigated. Fourier transform infrared (FTIR) spectrophotometer, High resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED) were used to measure the biomimetic synthesized silica films extracted with 0.50 mol·L-1 hydrochloric acid ethanol solution. The results indicate that the structure of hexagonal ordered mesoporous is maintained, while the surfactant is removed effectively in mesoporous silica films. |
