Abstract: A pigment comprising a plurality of photonic crystal particles dispersed in a medium, each photonic crystal particles containing a plurality of spectrally selective absorbing components dispersed within each photonic crystal particle that selectively absorb electromagnetic radiation without substantially absorbing electromagnetic radiation near a resonant wavelength of each photonic crystal particle, wherein each photonic crystal particle has a predetermined minimum number of repeat units of a photonic crystal structure, wherein the predetermined minimum number of repeat units is related to the resonant wavelength, the full-width at half maximum of the resonant wavelength, and the refractive index contrast in the photonic crystal.

Abstract: A structurally colored pigment is described that contains a plurality of photonic crystal particles dispersed in a medium, where each photonic crystal particles contains a plurality of spectrally selective absorbing components dispersed within the photonic crystal particle. In certain embodiments, each photonic crystal particle has a predetermined minimum number of repeat units of the photonic crystal structure. The structurally colored material provides improved reflectance, long-term stability, and control of the desired optical effects. The fabrication techniques described herein also provide high throughput and high yield allowing use in wide ranging applications from cosmetics, paints, signs, sensors, to packaging material.

Abstract: Methods and compositions disclosed herein relate to liquid repellant surfaces having selective wetting and transport properties. An article having a repellant surface includes a substrate comprising fabric material and a lubricant wetting and adhering to the fabric material to form a stabilized liquid overlayer, wherein the stabilized liquid overlayer covers the fabric material at a thickness sufficient to form a liquid upper surface above the fabric material, wherein the fabric material is chemically functionalized to enhance chemical affinity with the lubricant such that the lubricant is substantially immobilized on the fabric material to form a repellant surface.
