Abstract: GER fluids are improved by the addition of a polar molecule additive. By addition of a polar molecule additive, yield stresses under electric field are improved by over 50% while the current density is reduced to less than a quarter of the original GER. The reversible response time still remains the same, and the sedimentation stability is greatly enhanced. The zero field viscosity of the modified GER fluid remains the same as that of the original GER fluid without the additive. The improved GER characteristics improve general functionality as an electrical-mechanical interface, attendant with applications to car clutches, fluid brakes, and vehicle shock absorbers.
