Available in PDF, EPUB and Kindle. Book excerpt: Wormlike micelles (WLMs) have become widely used in a number of industrial and consumer products and processes where they come in contact with colloidal species. Still, relatively little is understood regarding the interactions between WLMs and colloids and resulting changes in macroscopic properties. As such, the goals of this thesis are to uncover the mechanisms by which WLMs interact with colloidal particles, and to determine how these interactions affect changes in macroscopic properties for mixtures of model WLMs and colloidal nanoparticles. Aqueous mixtures of cetyltrimethylammonium bromide (CTAB) and sodium nitrate (NaNO 3) serve as a model system in which to study the self-assembly, phase behavior and rheology of WLMs. Characterization of CTAB/NaNO 3 solutions across a wide range of state variables enables full exploration of WLM phase behavior, including micellization, the sphere-to-rod transition, overlap, and entanglement. Combining rheological measurements and small angle neutron scattering (SANS) yields measurement of the relevant length scales of WLMs, and provides a microstructural basis for the resulting changes in WLM rheology. In the concentrated regime, CTAB micelles undergo shear banding, an important flow instability that occurs in a variety of WLMs. Combination of rheometry, velocimetry, and spatially-resolved flow-SANS shows that shear banding of CTAB results from a shear-induced isotropic-paranematic phase transition. The use of a constitutive model enables direct, quantitative coupling of shear banding to equilibrium phase behavior, and enables construction of non-equilibrium phase diagrams for shear banding fluids. Establishment of structure property relationships for model WLMs thus serves as a basis for examining the interactions and changes in the resulting properties of CTAB/NaNO 3 WLMs in the presence of model cationically modified silica nanoparticles. Structural and thermodynamic measurements of interactions at the colloid-surfactant interface show that adsorption of surfactant results in the formation of hemimicellar surface structures, which in turn interact with WLMs to form micelle-nanoparticle junctions. These junctions give rise to unique rheological modification of WLMs, such as significant increase in viscosity and viscoelasticity, and arise from the contribution of effective cross-linking of the micellar solution to form a viscoelastic network. Furthermore, micelle-nanoparticle junctions suppress shear banding due to hindered orientational mobility of the micelles. Conversely, the formation of micelle-nanoparticle junctions gives rise to new colloidal interactions mediated by the bridging of micelles between particles, leading to thermoreversible phase separation of the colloid. In order to better understand and describe these interactions, a statistical mechanical model has been developed to capture the phenomenology of wormlike micellar bridging. The model predicts strong-long range attractions arising from the distribution in length of the micelles. Because the model is based on experimentally measureable parameters, it yields a priori predictions of interaction potential, which are in good agreement measurements of the colloidal phase behavior and of the second osmotic virial coefficient. The results of this work demonstrate that rheological properties of WLMs can be uniquely tuned by the addition of particles, and conversely the interactions of colloids in the presence can be uniquely controlled through the self-assembly of WLMs and interactions at the surfactant-colloid interface.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Surfactant flooding is a chemical enhanced oil recovery technique which has shown promise as an EOR method for the recovery of oil from maturing oil fields. It involves the injection of the surfactant mixture (surfactant and co-surfactant or solvent) into the reservoir to reduce the interfacial tension between the oil and water by creating a third phase (microemulsion) that contains equal amounts of oil and water. This reduction in the interfacial tension will allow for the production of the immobile oil that was previously trapped in the reservoir pores. For a successful surfactant EOR operation, the optimum surfactant formulation is necessary. In order to obtain the correct formulation for the selected reservoir a proper understanding of the effect of the different parameters on the phase behavior is needed. This includes considering the effects of salinity, high temperatures, high pressures and the equivalent alkane carbon number (EACN) among other considerations. While a significant number of studies have been done on surfactants in the past, very few papers have been published dealing with the combined effects of pressure and temperature on the multiphase microemulsion system. In this study we performed an extensive array of surfactant experiments at varying conditions of temperature, salinity, concentration, water-oil ratio (WOR), pressure and EACN for the same surfactant, therefore providing a comprehensive set of experimental results on the effect of the varying parameters on the phase behavior and solubilities using the selected surfactant. The effects of both alcohol and salt partitioning between the phases was investigated, empirical relations were developed to model the partitioning coefficients and the results were included in the interpretation of the surfactant microemulsion phase behavior. The results indicated that both alcohol and salt partitioning can affect the phase behavior and excluding either one can result in inaccurate interpretation of the phase behavior results. High pressure experiments were conducted on the same surfactant system at differing compositions to study the effect of pressure on the phase behavior, which showed that pressure can have a significant effect on the changes on phase behavior, shifting it from three phases to two phases and vice-versa. The changes in phase type and the location of the phase boundaries have been shown to depend on several factors which include temperature, the range of the three-phase window and how far the selected composition point is from the phase boundary. The results of these experiments were used to capture the main parameters of the HLD-NAC EoS that is used in the simulation model for surfactant calculations. The model results after tuning the parameters show good agreement when compared to the examined experimental data.
