Creep and recovery behaviors of a polythiophene-based electrorheological fluid

Magnetic field intensity effect on plane electric capacitor characteristics and viscoelasticity of magnetorheological elastomer

“…The creep and recovery behavior [32][33][34][35] of the MR elastomer disks were also measured. Under a load of shear stress, the ideal elastic material (Fig.…”

Pickering emulsion polymerized poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/polystyrene composite particles and their electric stimuli-response

“…This suggests that τ 0 depends on the conductivity mismatch between the polarizable particles and the liquid for the PEDOT:PSS/PSbased ER fluid. Dynamic oscillation tests were also carried out to examine the 15 viscoelastic behavior of PEDOT:PSS/PS-based ER fluid. The amplitude sweep experiment in Fig.…”

“…Furthermore, the synthesized PEDOT:PSS/PS composite particles 10 were dispersed in silicone oil with a particle concentration of 10 vol%, and then their ER response was investigated in the presence of an external electric field. Because of the presence of PEDOT:PSS, which adhered to the surface of insulating PS spheres, the PEDOT:PSS/PS composite particles can be applied 15 as an ER material. …”

Hysteresis and strain hardening in the creep response of a polyaniline ER fluid

“…For magnetorheological [20] and electrorheological [21] fluids, it has been established that increase of applied stress, relative to constant field strength, causes an evolution from a linear elastic, to linear viscoelastic response, with the above three components of instantaneous elastic strain, retarded elastic strain and viscous strain, then to a nonlinear viscoelastic response, where the retarded elastic and viscous strains monotonically decrease and a plastic contribution to the instantaneous strain grows, followed by a viscoplastic solid behavior, with fully plastic instantaneous strain, and finally a transition from plastic solid to viscous flow when the yield stress is exceeded.…”
