Fabrication of ordered microstructures based on self-assembled colloidal crystals

有关胶体晶体自组装以及以胶体晶体为模板制备有序图案化微结构方面的研究,由于方法简便、结构多样、重复性好等优点,近年来受到越来越多的关注.本文系统总结了我们在胶体微球和胶体晶体领域开展的研究工作,主要包括:无机或聚合物胶体微球的设计制备、纳米复合及功能化;结合聚合物材料可溶涨、可拉伸、热形变等特性构筑图案化胶体晶体、非球形对称胶体晶体、非紧密堆积胶体晶体等特殊结构;以胶体晶体为模板制备三维大孔骨架、纳米环、纳米碗阵列等有序微结构等.

Recently, much attention has been paid to self-assembled colloidal crystals and ordered microstructures fabricated using colloidal crystals as templates, because they possess such merits as convenient procedures, various possible structures and good repeatability. In this paper, we review our recent work on colloidal microspheres and colloidal crystals, that is the design, preparation, nanocomposite and functionality of inorganic and polymer colloidal microspheres; fabricating the patterned, nonspherical, non-close-packed and other complex colloidal crystal structures by utilizing the physical properties of polymer materials, such as swellable, stretchable and thermal transformable; fabricating the three-dimensional porous materials, nanorings, nanowell arrays and other microstructures by using colloidal crystals as templates.
