Abstract
Herein, rare‐earth element (lanthanum)‐doped MIL‐125 is synthesized via the solvothermal method. The morphology, physicochemical structure, specific surface area, and other characteristics of the synthesized material are characterized via scanning electron microscopy, transmission electron microscopy, X‐ray diffraction, Fourier transform infrared spectroscopy, Brunauer Emmett Teller, X‐ray photoelectron spectroscopy, element mapping, etc. It is observed that appropriate La doping enhances the dielectric mismatch and conductive mismatch levels of the material. This enhancement leads to a stronger interface polarization capability, thereby influencing the material's dielectric properties. Ultimately, the electrorheological fluids with La‐doped MIL‐125 as the dispersive phase show an obvious electrorheological effect.
