Electrorheological properties of a polyaniline–montmorillonite clay nanocomposite suspension

A new approach of enhancing the shear stress of electrorheological fluids of montmorillonite nanocomposite by emulsion intercalation of poly-N-methaniline

“…It are easy to polymerize them and control their conductance by varying the degree of doping. Based on this method, in our previous paper [26], we reported that the polyaniline/montmorillonite nanocomposites ER fluids have notable ER properties. In order to continue the study of organic polymer/clay nanocomposites' ER properties, we prepared poly-N -methaniline/montmorillonite nanocomposite ER particles (PNMA-MMT) using emulsion intercalation polymerization.…”

“…Commonly, it is well known that the parameters related to particle polarization, such as high dielectric constant, suitable conductivity, and dielectric loss, have been accepted as the physical basic factors which dominate high ER properties [26][27][28][29]. From the point of physical design, we proposed a method with which the effect of dielectric constant, conductivity, and dielectric loss on the ER fluid can be taken into account simultaneously [30][31][32].…”

“…Therefore, MMT has been widely used for preparing the organic-inorganic nanocomposite. On the basis of this point, some polymer/montmorillonite materials had been prepared [19][20][21][22][23], and some of them have also been used for ER fluids [22][23][24][25][26].…”

Styrene–butadiene–styrene/montmorillonite nanocomposites synthesized by anionic polymerization

“…Therefore, the nanocomposites possess unique properties that are not shared by conventional composites, such as excellent mechanical properties, high thermal stability, and enhanced barrier properties. In the past several years, many polymer/clay nanocomposites, such as polystyrene (PS)/clay, 7-11 rubber/clay, 12,13 polyurethane/clay, 14 -16 poly(ethylene oxide)/clay, 17,18 epoxy/clay, 19 -21 poly(methyl methacrylate), 22 polyamide/clay, 23 polyethylene/clay, 24 polypropylene/ clay, 25 polyaniline/clay, 26,27 and poly(lactic acid)/ clay, 28,29 have been found to show good properties. The styrene-butadiene-styrene triblock copolymer (SBS) has been widely used as a thermoplastic elastomer.…”

Preparation of intercalated polyaniline/clay nanocomposite and its exfoliation exhibiting dendritic structure

“…Recently, a solvent-free synthesis of polyaniline-clay nanocomposite is reported by mechanochemical intercalation method (Yoshimoto et al 2004). The electrorheological property of polyanilinemontmorillonite clay has been investigated extensively Lua and Zhao 2002). Apart from PANIclay nanocomposites, many other systems have also been synthesized based on intercalation method (Mortland and Pinnavaia 1971).…”
