Excerpt

Recently, Wei et al. [1] synthesized polyaniline–barium titanate (PAn–BaTiO3) nanocomposites by inorganic–organic in-situ complex technique and reported that the PAn–BaTiO3 nanocomposites based electrorheological (ER) fluid showed very high shear stress (2800 Pa) at 3.5 Kv/mm DC field compared with both the pristine PAn, and pure barium titanate. They attributed this superior ER performance to the interaction of PAn and BaTiO3. In this comment, we reanalyzed their ER data of shear stress which corresponds to dynamic yield stress as a function of applied electric field strengths via both the polarization and conductivity models. It is found that our universal yield stress equation collapses their data onto a single curve. …
