Research status and development trend of three-dimensional colloidal crystals

摘要

The three-dimensional colloidal crystal materials have unique optical properties and spatial structure due to their ordered arrangement and have great potential to prepare three-dimensionally ordered microporous (3DOM) materials. This review outlines various methods for preparing three-dimensional colloidal crystals (3DCCs). The preparation methods of commonly used colloidal particles are introduced in detail, and the effects of different parameters on the assembly of 3DCCs are discussed. On this basis, using the colloidal crystal template (CCT) method to prepare 3DOM materials. After that, the common stacking methods and defects of 3DCCs were analyzed. The latter part of this review discusses the main applications of 3DCCs, namely optical materials, adsorption materials, sensors, porous electrode materials, inverse colloidal crystal (ICC) scaffolds, and other popular applications in recent years.
