摘要：
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 nanostructures, which will find potential applications in sensors, optoelectronic devices, separation science and smart filters/flowmeters.
