摘　　要：近年来,由于具有特殊浸润性的胶体光子晶体膜在传感、检测、催化等方面的重要应用,胶体光子晶体膜的超浸润研究受到科研工作者的广泛关注.本文阐述了包括超亲液、超疏液、两亲性、梯度浸润性、可调控浸润性、图案浸润性等具有特殊浸润性光子晶体膜的制备及其相关应用,并讨论疏水、超疏水和亲-疏图案不同浸润性基底对所制备胶体光子晶体膜的功能性及其相关应用的影响.该工作对于发展新型功能型材料器件的制备具有重要的借鉴及指导意义.In recent years, the wettability of colloidal PCs has attracted much interest from researchers due to potential applications in printing, sensor, microfluidics and so on. In this paper, we present two kinds of research work related to PCs＇ wettability. On the one hand, the functional colloidal PCs have been fabricated from the modification of its wettability. Where, the wettability of PCs can be modified from superhydrophilic, superhydrophobic, amphiphilic, gradient wettability, controllable wettability and patterned wettability. Wettability is an important property of solid surface and can be generally controlled mainly by its surface chemical composition and surface topographic structure. Surface chemical composition determines surface free energy（i.e., hydrophilicity/hydrophobicity）, while the surface topographic structure can amplify hydrophilicity or hydrophobicity, based on the Wenzel and modified Cassie equation. Thus, PCs with specific wettability have been fabricated based on their intrinsic, well-ordered surface topographic structure, and chemical composition. The superhydrophilic and superhydrophobic PCs have been achieved based on the amplification effect of the surface well-ordered topographic structure. The gradient PCs have been fabricated by changing the topographic structure. The PCs with controllable wettability can be obtained when introducing a responsive group onto PCs＇ surface. The underwater oil-adhesion properties of PCs have been controlled by varying the latex from spherical or cauliflower-like to single cavity. On the other hand, functional PCs are fabricated from the substrate with specific wettability. Typically, high-quality and crack free PCs are achieved from superhydrophobic substrate, pattern PCs from the hydrophilic-hydrophobic substrate, PC dome with excellent wide-angle property is fabricated from hydrophobic substrate. Otherwise, gas-liquid or liquid-liquid interface has also been included as a special substrate for the fabrication of functional PCs, such as flower-sh
