ER Effect of PMMA Wrapped Alumina-Siloxane Gel Doped with Rare Earths
摘要
PMMA wrapped alumina-siloxane gel was obtained by using poly (methyl methacrylate) (PMMA) to wrap alumina-siloxane sol which was made from water glass, aluminum nitrate and α-methacrylic acid. Meanwhile, rare earth ions were used to dope in the course of reaction, and stable suspensions was produced by putting PMMA wrapped microcapsule powder doped with rare earths into methy-silicon oil. It is found that its electrorheological (ER) effect improves strikingly after loading electric field. At a certain concentration, the immediate viscosity increases from 95 to 178 Pa*s compared to the system without doping.
