Abstract

Inorganic-conducting polymer particles were prepared to enhance physical and chemical properties by forming hybrid nanocomposites, which would improve the electrorheological (ER) effect of their suspensions. Polypyrrole (PPy)–SnO2–methylcellulose nanocomposite particles were synthesized by controlling the ratio of pyrrole, SnO2, and methylcellulose during the polymerization. The ER and dielectric properties of the PPy–SnO2–methylcellulose nanocomposite suspensions were investigated. The ER response increases with the increase in the SnO2/pyrrole ratio and also depends on the amount of methylcellulose amount during the polymerization, showing a maximum ER behavior.
