Pickering emulsion polymerized smart magnetic poly(methyl methacrylate)/Fe₂O₃ composite particles and their stimulus-response

Abstract

Smart polymer/inorganic composite magnetic particles were synthesized by Pickering emulsion polymerization using magnetic iron oxide (Fe2O3) particles as a solid stabilizer.

Self-assembly of amphiphilic poly(styrene-b-acrylic acid) on magnetic latex particles and their application as a reusable scale inhibitor

“…The only feasible choice for the nanoparticles to locate is on the oil droplets, rather than in the water phase, by adsorbing to the oil-water interface and forming a dense lm (monolayer or multilayer) on the droplets. [24][25][26] At high amounts of OA-MNPs (12.0 w/v%), a threedimensional network is formed by particle-particle interactions, suppressing coalescence and generating a stable emulsion without the use of organic surfactants. This explanation is supported by dynamic light scattering (DLS) results, which reect that the prepared clusters have an average size of 165 nm with monodispersity (Fig.…”

Ultrasonic Studies of Emulsion Stability in the Presence of Magnetic Nanoparticles

“…However, it is possible to obtain a stable magnetic emulsion without surfactant stabilization. Magnetic nanoparticles, for example, magnetite particles suspended in a ferrofluid, can be used to stabilize the Pickering emulsion [11][12][13][14][15][16]. This is how a magnetic Pickering emulsion is formed.…”

Magnetorheology of a magnetic fluid based on Fe3O4immobilized SiO2core–shell nanospheres: experiments and molecular dynamics simulations

“…Several successful examples such as the PS/Fe 2 O 3 , PMMA/Fe 2 O 3 nanospheres were developed by Pickering emulsion polymerization. 34,35 Interestingly, the static yield stress of the above suspensions displayed a linear magnetic elddependency instead of the quadratic eld-dependency of the pure Fe 2 O 3 based MR uid. Therefore, the study of the magnetic uid based on the Fe 3 O 4 -immobilized particles became a pressing need in both applications and mechanism analyses.…”
