Although perovskite-structured materials have primarily been widely employed in solar cell applications, limited studies conducted the field of electrorheology (ER). In this study, various halide perovskite materials, including FAPbBr3, FAPbI3, MAPbBr3, MAPbI3, CsPbBr3, and CsPbI3 were synthesized for first time to evaluate their applicability ER time. Initially, morphological chemical properties these characterized confirm successful formation structures. addition, as-synthesized dispersed silicone oil (3.0 wt %) suitability as dispersants fluids. Among these, CsPbI3-based fluid exhibited optimal dielectric greatest dispersion stability systems examined. demonstrated highest performance, achieving a shear stress 99.4 Pa, owing synergistic effects its intrinsic rod-like structure properties, which promoted polarization. The aspect ratios rods further controlled by modifying synthetic process, resulting generation both shorter longer rods. Notably, fluids based on via hydrothermal method yielded structures with high ratio 20, leading an enhanced activity 128.0 Pa. These results highlight potential use applications.
