Synthesis and Electrorheological Characterization of Polyaniline/Barium Titanate Hybrid Suspension

Abstract

Abstract As organic/inorganic composites having attracted much attention due to their heterogeneous physical properties, conducting polyaniline (PANI) and barium titanate (BaTiO 3 ) which possesses large electronic resistance and excellent dielectric strength, were utilized to synthesize PANI/BaTiO 3 hybrid which is applicable for an electrorheological (ER) material via ‘in‐situ’ oxidative polymerization. Physical properties of the obtained PANI/BaTiO 3 composites were characterized via Fourier‐transform infrared spectra (FT‐IR), thermogravimetry analysis (TGA), and scanning electron microscopy (SEM). The ER behaviors were investigated via a rotational rheometer, and their shear stresses were fitted using our previously proposed rheological equation of state.
