摘要：
The electrorheological (ER) materials of pure SiO2(Sample 1), Ce-doping SiO2(Ce-SiO2, Sample 2) and Ce-SiO2adsorbed chitosan (Ce-SiO2-chitosan, Sample 3) were prepared using Na2SiO3, Ce(NO3)3and chitosan as starting materials. Their ER properties were studied. The results show that Ce-doping can enhance the ER activity of SiO2, and the ER activity of SiO2can be further improved by adsorbing chitosan on the surfaces of Ce-SiO2particles. The ER activity of a particle material is correlated with the average grain size, surface area, pore volume and average pore size of the material.
