The electrorheological property of a polyaniline-coated copolystyrene particle suspension

Electrically Induced Microstructures in Micro- and Nano-Suspensions and Related Physical Properties

“…Anhydrous ER fluids based on composite particles were also reported. [33][34][35] For a favorable level of induced stress, a series of surface-modified particles of sulfonated poly(styrene-co-divinyl benzene)s was developed by Asako et al 36 Recently, a suspension based on dry titanium dioxide (TiO 2 ) nano-particles has been reported by Tanaka et al 37 The suspended particles were remarkably stable against sedimentation and electrical breakdown. The nano-suspension also showed a good fluidity with a gap of 50 mm.…”

Electrically conducting suspensions formed by polyaniline

“…If it were to take liquid form, new functionalities could be conceived such as electric conduction and heat propagation in electrorheological properties [3][4][5]. The liquid polyaniline would possess not only electric conduction in liquid-like mercury but also redox properties.…”

The Effect of Polyaniline Content Deposited on Silica Gel Particles on the Electrorheology of Silicone-Oil Suspensions

“…Among them, semi-conducting polymers, such as polyaniline (PANI), polypyrrole, polythiophene, poly-p-phenylene and various copolymers have been shown to be most promising [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Especially the structured particles with different core/shell dielectric properties have been objects of recent investigation [21][22][23]. In our previous study [22] of various silicas coated with PANI, we have found that the polarizability of particles is not significantly affected by the shape and size of the core.…”
