Rheological properties of gamma irradiated Me3NC2H4OH+Zn2Cl5- and Me3NC2H4OH+Zn3Cl7- ionic liquids

摘要：

The objective of this work is to verify the rheological behavior of irradiated Me3NC2H4OH+Zn2Cl5- and Me3NC2H4OH+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. Gamma radiation causes a decrease of viscosity of Me3NC2H4OH+Zn3Cl7- by greater than 10%, but it does not impair the viscosity of Me3NC2H4OH+Zn2Cl5- (within the experimental error) except 20 kGy irradiated sample. The results show that the radiation stability of Me3NC2H4OH+Zn2Cl5- is higher than that of Me3NC2H4OH+Zn3Cl7T-.
