“…In contrast to coating PANI on the PMMA and PGMA surface, the process of coating PANI onto the PS is much simpler. Kim et al [ 125 ] and Liu et al [ 126 ] coated PANI on the surface of PS by the diffusion and polymerization of aniline at the interface without a surfactant or surface modification of PS. Scheme 7 presents a graphical diagram of the synthetic process.…”

Functional core-shell-structured particles have attracted considerable attention recently. This paper reviews the synthetic methods and morphologies of various electro-stimuli responsive polyaniline (PANI)-coated core-shell-type microspheres, including PANI-coated Fe 3 O 4 , SiO 2 , Fe 2 O 3 , TiO 2 , poly(methyl methacrylate), poly(glycidyl methacrylate), and polystyrene along with their electrorheological (ER) characteristics when prepared by dispersing these particles in an insulating medium. In addition to the various rheological characteristics and their analysis, such as shear stress and yield stress of their ER fluids, this paper summarizes some of the mechanisms proposed for ER fluids to further understand the responses of ER fluids to an externally applied electric field.

“…[ 19 ] but probably to its convenience for synthesis of well-shaped nano/submicron/micron-sized particles being very suitable for the (nano)composites with specific applications. For example, micron/submicron-sized PS particles coated with doped PANI were used in electrostatic accelerators, which allowed accelerating the charged particles to hypervelocities [ 20 ] or in electrorheological fluids [ 21 ], etc. Similar to other core-shell (nano)composites [ 22 ] PS/PANI ones obviously have potential for sensing applications.…”

This work is concentrated on synthesis and investigation of new core-shell nanocomposites of polystyrene (PS) with doped polyaniline (PANI). The latex containing PS nanoparticles with sizes of 15–30 nm was prepared by microemulsion polymerization of styrene in water media. The PS/PANI nanocomposites were synthesized by chemical oxidative polymerization of aniline in the PS latex media in a presence of lauryl sulfuric acid (LSA), which served as both dopant and plasticizer. The real content of PANI in the synthesized nanocomposites was determined by UV-Vis spectroscopy method. The composition of the nanocomposites and oxidation state of the doped polyaniline were characterized by FTIR spectroscopy. The core-shell morphology of the nanocomposite nanoparticles was proved by transmission and scanning electron microscopy. It was found that conductivity and thermal behavior in air of these nanocomposites not only nonlinearly depended on the doped polyaniline content but also were strongly effected both by plasticizing properties of the acid-dopant and presence of the polyaniline shell. A possibility of application of these nanocomposites as sensor materials has been demonstrated.

“…Nonetheless, the PS/PANI microsphere system has seldom been adopted as ER materials. 20 In this work, we synthesized semi-conducting PANI coated polystyrene (PS) core/shell microspheres (PS/PANI) by means of a facile and controllable method 21 without using any stabilizer 22,23 or grafting agent. 24 We expect a better PANI coating onto PS with a p-p stacking interaction than previously reported coating onto poly(methyl methacrylate) microsphere.…”
