Synthesis of Transparent and Field‐Responsive BaTiO₃ Particle/Organosiloxane Hybrid Fluid

Abstract

A smart fluid containing BaTiO3 nanoparticles was synthesized by a chemical solution process. The transparent and homogeneous fluid (see picture) changes its rheological properties in response to an electric field. Formation of aligned structures from nanoparticles under shear stress (arrow) was confirmed by 3D confocal fluorescence microscopy (white dots: fluorescein-modified nanoparticles).
