Structurally Colored Aerogels
Structural color is a fascinating method employed in nature to achieve vibrant hues. Examples abound, from Iridescent opals to the delicate hues of butterfly wings, and the shimmering scales of beetles1 (Figure 1 a-c). Unlike conventional pigments, structurally colored materials boost resilience against photobleaching and can be easily designed to circumvent environmental and chemical hazards. This characteristic renders them an attractive sustainable alternative for various photonic applications.2,3 Renowned for their ultralow thermal conductivity and open pore structure, Aerogels find widespread use scenarios in thermal insulation, catalysis, environmental remediation, and optics.4 Among these applications, currently, thermal insulation stands out prominently, and an aerogel with intrinsic structural color holds the promise for sustainable and smart coloring endeavors.

Here we aim to create aerogels from colloidal building blocks of 200-300 nm sizes that are on the order of visible light and, therefore, are expected to emerge colors tuneable by the size of the particles used. The project is a collaboration between EMPA Dübendorf and the University of Fribourg groups with expertise in aerogels and structural color, respectively.
