Graphene and graphene oxide composites and their electrorheological applications

Abstract

Graphene oxide (GO) based composite systems have been fabricated and investigated as a novel electroresponsive electrorheological (ER) dispersed phase because of their proper electrical conductivity and polarizability for their ER application, in addition to graphene composites. This paper briefly reviews mechanisms of the fabrication of various graphene and GO based composites and their critical ER characteristics including flow curve, yield stress, and dynamic properties measured using a rotational rheometer. Relaxation time and achievable polarizability from dielectric analysis using a LCR meter are also discussed.
