Graphene oxide nanocomposites and their electrorheology

• GO-based PANI, NCOPA and PS nanocomposites are prepared.
• The nanocomposites are adopted as novel electrorheological (ER) candidates.
• Their critical ER characteristics and dielectric performance are analyzed.
• Typical ER behavior widens applications of GO-based nanocomposites.

Graphene oxide (GO), a novel one-atom carbon system, has become one of the most interesting materials recently due to its unique physical and chemical properties in addition to graphene. This article briefly reviews a recent progress of the fabrication of GO-based polyaniline, ionic N-substituted copolyaniline and polystyrene nanocomposites. The critical electrorheological characteristics such as flow response and yield stress from rheological measurement, relaxation time and achievable polarizability from dielectric analysis are also analyzed.
