Synthesis and Electrorheology of Semiconducting Poly(naphthalene quinone) Radical Particles

Electrorheologically intelligent polyaniline and its composites

“…So, the focus has been turned to organic materials, and conducting polymers which possess conjugated π 60-62 bonds have been gradually adopted as ER materials because this type of materials possesses the capability of being polarized under an electric field, thus indicating high dielectric constant. [63][64][65][66][67][68][69][70][71][72][73][74] Besides this, those which have high polarizable functional groups on the molecular backbone can also be applied as an ER material. Among all the applicable conducting polymers, the PANI has been regarded as an essential candidate for the ER materials owing to its high conductivity, easy synthesis, good environmental stability, and various potential applications such as electrochromic devices, chromatography, electrostatic discharge protection and corrosion-protecting paint.…”

Preparation of polyaniline coated poly(methyl methacrylate) microsphere by graft polymerization and its electrorheology

“…Among the many promising materials for ER suspensions, conducting polymers in a semiconducting regime including polyaniline (PANI) [9,10], copolyaniline [11], poly(p-phenylene) [12], polythiophene [13], polyphenylenediamine [14], poly(acene quinine) radicals [15], and polymer-inorganic nanocomposite [16,17], have been adopted as anhydrous dry-base ER fluids because of their ease in handling and superior physical properties, compared to various hydrous wet-base ER materials [18].…”

Scaling of Yield Stress of Polythiophene Suspensions under Electric Field

“…[2][3][4][5] Typically, the steady-state rheological properties have been investigated for most ER fluids. [6][7][8][9][10][11][12][13][14] The steady-state rheological response in shearing flows is commonly modeled as a Bingham fluid, [15,16] with an electric field dependent yield stress, t y (E 0 ),…”
