Layer-by-layer strategy for the general synthesis of 2D ordered micro/nanostructured porous arrays: structural, morphological and compositional controllability†
Abstract
In this paper, the general synthesis of two-dimensional (2D) ordered porous micro/nanostructured arrays by a layer-by-layer strategy based on the 2D colloidal template transfer are systematically studied. Using such a strategy, various 2D ordered porous films including hetero-pore sized, heterostructured and ion-doped porous films can be fabricated on any desired substrates. Moreover, the film thickness, chemical composition and packing geometry of the porous film also demonstrate a good manner of controllability. The formation mechanisms of these structures are briefly discussed. This synthetic route is highly expected to advance the synthesis of functional patterned 2D ordered porous
