超疏水表面是基于涂有多层嵌段共聚物胶束的二氧化硅胶体制备的（见图）。分级表面粗糙度可以通过调节聚合物链段的pH值和分子量来调节。如图所示，疏水核中包含量子点或有机染料，从而赋予薄膜光学功能。[图形]
Superhydrophobic surfaces are prepared based on silica colloids coated with multiple layers of block copolymer micelles (see figure). The hierarchical surface roughness can be tuned by adjusting the pH and molecular weight of the polymer segments. Optical functionality is imparted to the films by the inclusion of quantum dots or organic dyes in the hydrophobic cores, as depicted in the figure.[GRAPHICS]
