利用具有有序凸起排列的金属模具，通过纳米压痕对钛进行预织构，得到了理想有序的阳极多孔二氧化钛。在随后的阳极氧化过程中，通过纳米压痕制备的浅凹作为空穴形成的起始点，生成了理想的六方有序的多孔状或纳米管状的二氧化钛。通过改变预织构图案可以控制理想有序的二氧化钛的空穴间距。该工艺是朝着需要理想有序的无缺陷孔或孔布置的各种类型的功能器件的制备的关键步骤。(C)2014爱思唯尔B.V.保留所有权利。
Ideally ordered anodic porous TiO2 was fabricated through the pretexturing of Ti by nanoimprinting using a metal mold with an ordered array of convexes. The shallow concaves prepared by nanoimprinting acted as initiation sites for hole development during the subsequent anodization and generated ideally hexagonally ordered porous or nanotubular TiO2. The hole interval of the ideally ordered TiO2 could be controlled by changing the pretexturing pattern. This process is a key step towards the preparation of various types of functional devices requiring ideally ordered defect-free hole or pore arrangements. (C) 2014 Elsevier B.V. All rights reserved.
