Surface modification of dielectric materials changes the dipole–dipole interactions under electric fields, thereby controlling electrorheological (ER) response. The introduction metal oxides onto mica templates and further coating dyes is expected to simultaneously improve color clarity ER performance. Dye-coated TiO2 platelets on are synthesized for high-performance colorful fluids. A sol–gel method utilized grow prepare precursor light-colored mica/TiO2 materials, which coated with appropriate enhance vividness as determined by Commission Internationale de clairage L*a*b* system. expression improvement explained via light interference effect presence chromophores. uniform layers can be obtained low pH conditions controlled nucleation kinetics. addition increases surface area porosity introduces heteroatoms that act positive factors. In practical applications, dye-coated TiO2-based fluids exhibit higher performances compared corresponding vivid-colored could provide an easy selection a wide range rheological systems requiring specific magnitude stress confirming color.
