Using SiO2 with a diameter of 12nm as the dispersed phase and polyethylene glycol (PEG200,PEG400) with different molecular weights as the dispersion medium,shear thickening fluid (STF) with different concentrations(26%,28%,30%,32%,34%) were prepared by mechanical stirring and ultrasonic vibration The steady-state rheological properties of STF were tested by Anton Paar MCR102 rheometer,and the influence of concentration and dispersion medium on the steady rheological properties was studied.The results shown that the maximum viscosity of STF increased with the increase of concentration,the response time of shear thickening decreased with the increase of concentration The rheological property of STF system with dispersion medium of PEG200 was better than that of PEG400.
