Well controlled core/shell type polymeric microspheres coated with conducting polyaniline: fabrication and electrorheology

Electrorheological, viscoelastic, and creep‐recovery behaviors of covalently bonded nanocube‐TiO2/Poly(3‐octylthiophene) colloidal dispersions

“…It was concluded that nanocube‐TiO 2 particles were successfully coated with conducting P3OT chains, formed strong fibrils and become an ER active material. These results are in accordance with the OM study carried out on nanosphere‐TiO 2 , nanosphere‐TiO 2 /PPy [7] and microsphere poly(methylmethacrylate)/polyaniline core/shell hybrid materials .…”

Carbonization of aniline oligomers to electrically polarizable particles and their use in electrorheology

“…The suspension based on the original sample prepared in 0.5 M NH 4 OH solution exhibits the lowest ER effect. It also shows the typical decrease in shear stress at low shear rates for an ER fluid with a small ER effect, which has been previously commented in the literature [42,43]. Such behavior is caused by breaking of internal structures together with their difficult reformation under the shear flow.…”

Stimuli-Responsive Polymers and Colloids under Electric and Magnetic Fields

“…Therefore, the shear stress generated decreases with increasing shear rate. Hydrodynamic repulsive interactions dominate in the high shear rate region, where fibril particle structures are fully destroyed without re-formation, and the suspension behaves like a pseudo-Newtonian fluid [84]. Compared to the Bingham model, the suggested CCJ model explained the experimental flow curves well, particularly at the low shear rate range.…”

“…In addition, the second one controls the fitting in a high shear rate region where the shear stress increases and then tends to converge to a uniform line as the shear rate reaches to an extremely high value. The exponent β has the range 0 < β ≤ 1, because 84]. Note that the CCJ model has been also adopted into various ER materials [85,86].…”
