Living organisms construct various forms of laminated nanocomposites through directed nucleation and growth of inorganics at self-assembled organic templates at temperatures below 100°C and in aqueous solutions. Recent research has focused on the use of functionalized organic surfaces to form continuous thin films of single-phase ceramics. Continuous thin films of mesostructured silicates have also been formed on hydrophobic and hydrophilic surfaces through a two-step mechanism. First, under acidic conditions, surfactant micellar structures are self-assembled at the solid/liquid interface, and second, inorganic precursors condense to form an inorganic-organic nanocomposite. Epitaxial coordination of adsorbed surfactant tubules is observed on mica and graphite substrates, whereas a random arrangement is observed on amorphous silica. The ability to process ceramic-organic nanocomposite films by these methods provides new technological opportunities.
生物有机体通过在低于100℃的温度下于水溶液中在自组装有机模板上进行无机物的定向成核和生长来构建各种形式的层状纳米复合材料。最近的研究集中在使用功能化有机表面来形成单相陶瓷的连续薄膜。介孔结构硅酸盐的连续薄膜也已通过两步机制在疏水和亲水表面上形成。首先，在酸性条件下，表面活性剂胶束结构在固/液界面处自组装，其次，无机前体缩合形成无机-有机纳米复合材料。在云母和石墨基板上观察到吸附的表面活性剂小管的外延配位，而在无定形二氧化硅上观察到随机排列。通过这些方法加工陶瓷-有机纳米复合薄膜的能力提供了新的技术机会。
