| Abstract: | Field-induced rheological properties were studied for pure magnetic fluids (MFs) and 5% MF–cetyltrimethylammonium bromide (CTABr) emulsion for varying CTABr concentration (0–0.1 M) at different temperatures. The zero-field rheological study for 5% MF–CTABr emulsion shows maximum viscosity for 0.01 M CTABr concentrations. In-field viscosity results for 0.01 M CTABr–MF emulsion shows nearly 10 times more change in viscosity than the pure fluid, indicating the interaction between micelles and magnetic particles. |
