“…In order to overcome the shortcomings of solid state synthesis method, such as high sintering temperature, large grain size and low purity, hydrothermal synthesis method is used to fabricate BaTiO3 particles. [30][31] In this process, the precursors are put into a stainless steel autoclave and react under heating and pressure. [32] Hydrothermal synthesis method fabricates BaTiO3 particles with low dielectric loss at low synthesis temperature.…”

“…Since EREs combine the advantages of both electrorheological fluid and elastomer, it can overcome the shortcomings of easy to precipitate and weak stability for 2 ordinary hydrogel. The dispersed particles in ERE would form specific anisotropic structures under electric field, which caused mechanical modulus changed significantly and showed potential for the application in electric field-modulated wave-absorbing material [17][18][19][20]. However, high ERE rheological activity for close level of electrorheological fluid has become a major challenge.…”

As a member of smart materials, electrorheological elastomers (EREs) formed by pre-treating active electrorheological particles are attracting more and more attention. In this work, four Mg-doped strontium titanate particles with spherical, dendritic, flake-like and pinecone-like morphorlogies were obtained by hydrothermal and low-temperature co-precipitation. XRD, SEM, Raman and FT-IR were used to characterize the obtained products. The results showed that the sizes of Mg-doped strontium titanates are about 1.5‒2.0 μm, and the phase structure are dominated by cubic crystal. These Mg-doped strontium titanates were dispersed in a hydrogel composite elastic medium. Then, Mg-doped strontium titanate/glycerol/gelatin electrorheological composite hydrophilic elastomers were obtained with or without electric field. The electric field response properties of Mg-doped strontium titanate composite elastomers were investigated. It concluded that dendritic Mg-doped strontium titanate composite elastomers is high-performance EREs. And the maximum value of energy storage modulus of Mg-doped strontium titanate composite elastomers has achieved 8.70 MPa. This high electrorheological performance of the products is helpful for their applications in vibration control, force transducers, smart structures, dampers, and other fields.
