Caicedo-Casso Purdue MSE Ph.D. Final Exam Advisor: Professor Kendra A. Erk ABSTRACT The successful transformation of microstructured (complex) fluids into commercial products often relies on the ability to understand and control their rheological behavior. However, the implementation of rheological frameworks to drive business decisions is challenging. Majority of these fluids contain a wide variety of mesoscopic phases that contribute to a convoluted and distinct rheological response. Therefore, it is essential to combine flow characterization techniques with proper physical measurements to fully elucidate the root causes of the rheological behavior of microstructured fluids. In this order of ideas, this doctoral dissertation shows the development of three protocols of applied shear rheology. These protocols aim to advance the transformation of novel self-assembly block copolymers, concentrated surfactant solutions, and water-soluble polymers into real products. A robust set of experimental evidence is used to bridge the mesoscopic signatures of each microstructured fluid to their flow behavior. This talk focuses on the demonstration of the critical factors (chemical, physical, or thermodynamical) that could potentially drive the rheological behavior thus the successful transformation of the studied microstructured fluids. The novelty of this work lies in the integration of simple rheological measurements, scattering characterization techniques, mass transfer measurements, and advanced rheo-flow velocimetry to draw meaningful conclusions relevant to current industrial demands Date: Wednesday, April 17, 2019 Time: 3:00 P.M.
