Synthesis and characterization of new electrorheological fluids by carboxymethyl starch nanocomposites

Electrorheological fluids are new materials with good properties such as dielectric constant, dielectric loss or conductivity. These materials find practical applications in various industries. In this paper have been studied a ternary nanocomposite as rheological fluid based on Carboxymethyl starch and dimethylsulfoxide with feldspar particles. These nano composite was prepared by the two-step composite method. Firstly, the polar DMSO compound was directly intercalated into the interlayer of nano ferric oxide and then the intercalated complex was composite with CMS by the solution method. The composites, thus synthesized have been characterized by Fourier transfer infrared (FT-IR) spectrophotometer and X-ray diffraction. The morphology of these composites was studied by scanning electron microscopy.
