Enhanced electrorheological characteristics of titanium oxide@H2Ti2O5 nanotube core/shell nanocomposite

Abstract In this work, an electrorheological (ER) fluid containing titanium oxide@ H 2 Ti 2 O 5 nanotube core/shell nanocomposite was prepared via the combination of hydrothermal and solvo-thermal method. The morphological evolution was studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques. Furthermore, the structural characteristics of the as-obtained core/shell nanoparticles were confirmed by x-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) and nitrogen adsorption measurements respectively. Titanium oxide@H 2 Ti 2 O 5 nanotube core/shell nanocomposite is showed to possess tube-like and core-shell structure and enhanced ER properties under external electric fields.
