Electro-rheological fluid comprising polyaniline-clay nanocomposite

摘要

The present invention provides an electro-rheological fluid based on an organic and inorganic nanocomposite, that is, polyaniline-Na^{-MMT clay nanocomposite, which is in a layered structure. The polyaniline-Na-MMT clay nanocomposite particles can be synthesized by an emulsion polymerization. New ER fluid comprising polyaniline-clay nanocomposite particles dispersed in a non-conductive medium shows that shear stress remains almost constant when increasing shear rate, as well as when being applied various electric fields, even in high shear region, and has a good thermal stability.}
