The objective of this work is to verify the rheological behavior of irradiated [Me3NC2H4OH]+[Zn 2Cl5]- and [Me3NC2H 4OH]+[Zn3Cl7]- ionic liquids in comparison to the unirradiated ones, the viscosities were measured by a strain-control experiment under different irradiation doses' samples(0, 10, 20, 50, 100 kGy) at different shear rates and temperatures. The curves of shear stress against shear rate present that the viscosity of ionic liquid is insensitive to shear rate;the viscosity of ionic liquids decreases with increasing temperature, and can be fitted by Arrhenius equation very well.
