This project focusses on self-assembling rattle particles into supraparticles to produce structural colors that can be turned on and off, without suffering from angle dependent properties.
Currently, most colors in paints and coatings consists of pigments. Over time, these tend to chemically degrade resulting in a loss of color. An alternative would be to use structural colors which do not degrade over time. Currently structural colors are hindered by their angle dependence. In this project this angle dependence will be tackled by self-assembling particles into ordered supraparticles. The constituents of these supraparticles will have tunable properties that can be used to switch the structural color on and off by external fields. Via this additional functionality the supraparticles could be used for smart coating applications as well.
