作为一类重要的二维材料,二维有序多孔薄膜受到人们的广泛关注.气液界面胶体球刻蚀法是近些年发展起来的一种以漂浮在液面上的单层胶体晶体为模板来制备二维有序纳米结构的方法,具有简单、高效、重现性好、适用范围广以及结构参数易调变等优点.近年来,我们课题组利用气液界面胶体球刻蚀法实现了包括多种无机物纳米网、纳米碗阵列和纳米网-纳米碗复合阵列在内的一系列自支撑二维有序多孔薄膜的可控制备,考察了其二维光子晶体性质,并研究了其在刻蚀掩膜、溶剂检测、生物传感、电阻开关器件、光电化学分解水等方面的应用.本文在重点介绍我们课题组研究进展的同时,也简要总结了该领域的整体发展状况并展望了该领域的今后发展方向.
As a kind of important two-dimensional material, two-dimensional ordered porous film has drawn much attention from people.The gas-liquid interface colloidal ball etching method developed in recent years is a single-layer colloidal crystal floating on the surface of liquid Template to prepare two-dimensional ordered nanostructures, has the advantages of simple, high efficiency, good reproducibility, wide application range and easy adjustment of structural parameters, etc. In recent years, our research group has implemented the gas-liquid interface colloidal ball etching The controlled preparation of a series of self-supporting two-dimensional ordered porous films including various inorganic nanowires, nanowell arrays and nanowire-nanowire composite arrays was investigated. The properties of the two-dimensional photonic crystals were also investigated. It is used in etching mask, solvent detection, biosensor, resistance switch device, photoelectrochemical decomposition water, etc. This article mainly introduces the research progress of our research group, at the same time it briefly summarizes the overall development of this field Looking forward to the field of future development.
