Electric Field-Responsive Mesoporous Suspensions: A Review

Nanomaterials (Basel). 2015 Dec 15;5(4):2249-2267. doi: 10.3390/nano5042249.


This paper briefly reviews the fabrication and electrorheological (ER) characteristics of mesoporous materials and their nanocomposites with conducting polymers under an applied electric field when dispersed in an insulating liquid. Smart fluids of electrically-polarizable particles exhibit a reversible and tunable phase transition from a liquid-like to solid-like state in response to an external electric field of various strengths, and have potential applications in a variety of active control systems. The ER properties of these mesoporous suspensions are explained further according to their dielectric spectra in terms of the flow curve, dynamic moduli, and yield stress.

Keywords: electrorheology; mesoporous; nanocomposite; suspension.
