This article demonstrates the method of computer numerical simulation of polymer-surfactant flooding. According to the feature of polymer-surfactant flooding, account is taken of the adsorption and dispersion of polymer component and surfactant component in stratum and mathematical model of each component has been established. The difference method has been adopted to solve mathematical model and...
In this work, homogeneous dispersion of multiwall carbon nanotubes (MWCNTs) in the hydrophilic polymer poly (vinyl)alcohol (PVA) in the presence of organic surfactant sodium dodecyl sulfate (SDS) was achieved. Further, thermal analysis shows that carbon nanotubes increase the glass transition temperature Tg and nucleate PVA crystallization. The observed results from Raman spectra recorded with 785...
Surfactants have been used for different industrial and cosmetic purposes for decades. Most industrial formulations are complex mixtures of many different chemicals. Often, more than one component is surface active. In this paper we present the results of studies on the colloid stability and dispersion of metal oxide powders in anionic surfactant solutions with nonionic or long chain anionic surface-active...
