摘要

<正>Colloidal photonic crystals (PCs) with desired wettabilities are of particular importance in various applications. Inspired by biological PCs, such as those of butterfly wings and peacock feathers, which all have evolved to have specific wettability, Professor Song Yanlin and his group in the Laboratory of New Materials, Institute of Chemistry, Chinese Academy of Sciences developed unique approaches to engineer colloidal PCs with desired wettability, based on the well-designed building blocks of latex particles. The range of wettability of these col- loidal PC films could be tailored from superhydrophobicity to superhydrophilicity and even superoleophobicity, by varying the surface
