Electrorheological properties and creep-recovery behavior of polythiophene/polyoxymethylene-blend having PT(50%)/POM(50%) composition were investigated.Particle size,conductivity and dielectric values were measured to be 24.77μm,3.85×10~(-5) S·m~(-1) and 26.75,respectively.Sedimentation ratio was measured to be 64%at the end of 16 days.The effects of dispersed particle volume fraction,external electric field strength,shear rate,frequency and temperature on ER properties and storage modulus of PT/POM-blend/silicone oil(SO) suspensions were examined.Enhancement were observed in the electric field viscosities of the suspensions and thus they were classified as a smart material.Shear thinning non-Newtonian viscoelastic behavior was determined for PT/POM-blend/SO system.Further,time-dependent deformation was examined by creep-recovery tests and recoverable viscoelastic deformation established.
Electrorheological properties and creep-recovery behavior of polythiophene / polyoxymethylene-blend having PT (50%) / POM (50%) composition were investigated. Particle size, conductivity and dielectric values were measured to be 24.77 μm, 3.85 × 10 -5 ) S · m ~ (-1) and 26.75, respectively. Sedimentation ratio was measured to be 64% at the end of 16 days. The effects of dispersed particle volume fraction, external electric field strength, shear rate, frequency and temperature on ER properties and storage modulus of PT / POM-blend / silicone oil (SO) suspensions were examined. Enhancement were observed in the electric field viscosities of the suspensions and thus they were classified as a smart material. Hear thinning non-Newtonian viscoelastic behavior was determined for PT / POM-blend / SO system. Future, time-dependent deformation was examined by creep-recovery tests and recoverable viscoelastic deformation established.
