A Computer Simulation and Molecular-Thermodynamic Framework to Model the Micellization of Ionic Branched Surfactants in Aqueous Solution
Surfactants, or surface active agents, are chemicals exhibiting amphiphilic behavior toward a solvent. This amphiphilic character leads to increased activity at interfaces and to self-assembly into micellar aggregates beyond a threshold surfactant concentration, referred to as the critical micelle concentration (CMC), in bulk solutions. As a result of these unique attributes, surfactants are us...
متن کاملSelf-Assembly Structures of Nonionic Surfactants at Graphite/Solution Interfaces
The interfacial self-assembly structures of a series of poly(oxyethylene) n-dodecyl ether (C12En) nonionic surfactants on graphite has been imagedby atomic forcemicroscopyusing only the steric stabilization force as the contrast mechanism. Aggregates are arranged in parallel stripes perpendicular to the underlying graphite symmetry axes for C12E5-C12E10. These are interpreted as hemicylindrical...
متن کاملA Brief Review of Polymer/Surfactant Interaction
This brief review of polymer-surfactant interaction opens by describing how polymers behave in solution. Then we survey the literature on the interaction of nonionic polymers with surfactants, and the interaction of polyelectrolytes with ionic surfactants of opposite charge. After a brief discussion of polymer adsorption at interfaces, we consider the implications of these interactions on the d...
متن کاملBlock copolymer assembly to control fluid rheology
Recent experimental studies on the rheology of block copolymer micelles are reviewed. Where appropriate, we draw analogies between the viscoelastic properties of polymeric micelles and those of colloidal dispersions. We also present some important differences between these two classes of complex fluids, namely the ability to tune self-assembly through solvent polymer interactions. Finally, new ...
متن کاملInvestigation of the effects caused by applying voltage in Layer-by-Layer self-assembly method
Recently, Layer-by-Layer (LbL) self-assembly method under applied voltage (voltage-applied LbL) attracts great attention. It is reported that the method enables more abundant film adsorption than conventional LbL method. However, a small proportion of experimental results about adsorption of polyelectrolytes by voltage-applied LbL have been reported. In this study, voltage-applied LbL method us...
