Synthesis and Electrorheological Properties of SiO2/Polyaniline Nanocomposites Prepared by In Situ Polymerization

Abstract:

SiO2/polyaniline (PANI) nanocomposites were obtained by chemical oxidative polymerization using ammonium peroxydisulfate as oxidizing agent. The FE-SEM and TEM images showed that nanocomposites presented the core-shell structure with raspberry morphology. The electrorheological (ER) effect of those materials was enhanced by using the ammonium hydroxide to deprotonate the corresponding PANI base. It was found that the yield stress of those ER fluids and its near linear dependence on the electric field were different from the conventional ER fluids.
