“…A number of studies have confirmed surfactant adsorption onto nanoparticles through contact angle measurements, adsorption isotherms of surfactants on nanoparticles, zeta potential measurements and dispersion stability measurements as a function of concentration of surfactant and nanoparticles . Surfactant‐coated nanoparticles generate stable foams and emulsions in some cases where precursor nanoparticles or surfactants separately do not …”

Enhanced oil recovery (EOR) processes aim to recover trapped oil left in reservoirs after primary and secondary recovery methods. New materials and additives are needed to make EOR economical in challenging reservoirs or harsh environments. Nanoparticles have been widely studied for EOR, but nanoparticles with polymer chains grafted to the surface-known as polymercoated nanoparticles (PNPs)-are an emerging class of materials that may be superior to nanoparticles for EOR due to improved solubility and stability, greater stabilization of foams and emulsions, and more facile transport through porous media. Here, we review prior research, current challenges, and future research opportunities in the application of PNPs for EOR. We focus on studies of PNPs for improving mobility control, altering surface wettability, and for investigating their transport through porous media. For each case, we highlight both fundamental studies of PNP behavior and more applied studies of their use in EOR processes. We also touch on a related class of materials comprised of surfactant and nanoparticle blends. Finally, we briefly outline the major challenges in the field, which must be addressed to successfully implement PNPs in EOR applications. V C 2014 Wiley Periodicals, Inc. J. Appl. Polym.

“…Zeta potential, a very good index of the magnitude of the interaction between colloidal particles, is commonly used to assess the stability of colloidal systems. The dividing line between stable and unstable suspensions is generally taken at either +30 or −30 mV . Particles with zeta potential more positive than +30 mV or more negative than −30 mV are normally considered stable.…”

A core-shell fluorine-silicon modified polyacrylate hybrid latex was successfully prepared via emulsifier-free emulsion polymerization. The chemical composition and core-shell morphology of the resultant hybrid particles were investigated using 1 H NMR and Fourier transform infrared spectroscopies and transmission electron microscopy (TEM), respectively. TEM analysis indicated that the core-shell hybrid particles were uniform with narrow size distributions. The particle size and zeta potential decreased with an increase of alkylvinylsulfonate surfactant from 2.5 to 6.0 wt%. X-ray photoelectron spectroscopy revealed that fluorine concentrated preferentially at the film surface during a film-formation process. The film formed from the fluorine-silicon modified polyacrylate showed much higher thermal stability than a film formed from polyacrylate and fluorine-modified polyacrylate. Contact angle results showed that a finished fabric had remarkable water repellency.

“…Various researchers have explored the use of LSCM to investigate the nature of the solidliquid-gas interface in foams (Liu et al, 2009;Zhang et al, 2008;Fujii et al, 2006;Reed et al, 1997;Lau & Dickinson, 2005;Dong et al, 2010). Zhang and subsequently Liu investigated aqueous foam stabilized with Laponite particles modified by a surfactant.…”
