Abstract

We synthesized poly(ethyleneglycol) based urethane (UPEG) end-capped with methanol (MUPEG) and with ethyl lactate (LUPEG), and carried out the rheological measurements with immiscible blends composed of (M,L)UPEG and polydimethylsiloxane (DMS). The viscosity of the UPEGs increased under an electric field. LUPEG shows higher viscosity than MUPEG at all shear rates examined. MUPEG is a Newtonian fluid under no field, while LUPEG behaves as a non-Newtonian fluid. It is considered that LUPEG forms initial structure under no field at low shear rate, which affects the ER effect.
