Cover Story: With the invention of novel colorful electrorheological (ER) fluids, ER performances are correlated with their colors to allow for the visual selection of the appropriate fluid for a specific application using naked eyes. A series of TiO2-coated synthetic mica materials colored white, yellow, red, violet, blue, and green are fabricated via a facile sol–gel method. The colors are controlled by varying the thickness of the TiO2 coating layer, as the coatings with different thicknesses exhibited different light interference effects. The underlying mechanism of colored ER fluids is explained in terms of electrical conductivity, dispersion stability, and ion concentrations of materials. View this paper
