本文综述了一种基于模板的纳米材料制备方法。该方法涉及在纳米多孔膜的孔内合成所需的材料。我们将这种方法称为模板合成，因为这些纳米孔膜中的孔可以作为模板来合成所需材料的纳米结构。由于这些膜内的孔是圆柱形的且直径均匀，因此可以获得所需材料的单分散纳米柱状物。根据孔壁和材料的化学成分，这些纳米柱状物可以是中空的(管状)，也可以是固体的(纤维或纳米线)。该模板工艺将被证明是由包括聚合物、金属、半导体、碳和其他材料在内的各种材料组成的纳米管和纤维的一种非常通用的制造方法。
This article reviews a general template-based approach for the preparation of nanomaterials. The method involves the synthesis of a desired material within the pores of a nanoporous membrane. We have termed this approach 'template synthesis' because the pores within these nanoporous membranes act as templates for the synthesis of nanostructures of the desired material. Because the pores within these membranes are cylindrical and of uniform diameter, monodisperse nanocylinders of the desired material are obtained. Depending on the chemistry of the pore wall and material, these nanocylinders may be either hollow (a tubule) or solid (a fibril or nanowire). This template process will be shown to be a very general approach in the fabrication of nanotubes and fibrils composed of a variety of materials including polymers, metals, semiconductors, carbons, and other materials.
