Self-assembly of Block Polymers: Self-Consistent Field Theory and Monte-Carlo Simulations
Block polymers are a class of soft materials that self-assemble at mesoscopic length scales to form a wide variety of ordered structures. The resulting nanostructures have been instrumental in the development of several advanced technologies such as separation membranes and photonic crystals. This …

Structure-property behavior of free radical synthesized polydimethylsiloxane-polystyrene block polymers and polytetramethyleneoxide based ionene elastomers
… (PDMS) - polystyrene and PDMS-styrene derivative block polymers have been studied. The block polymers were provided by Dr. J. V. Crivello from GE. Two different types of segmented polytetramethyleneoxide (PTMO) based ionene elastomers were also investigated. The PTMO-dihalide ionenes were obtained …

Understanding self-assembly and flow heterogeneities in poloxamer wormlike micelles
… Although the structure of WLMs resembles that of polymers, WLMs are differentiated by their ability to break and recombine at rest and in response to deformations. This unique property has led to their ubiquitous use in a variety of applications such as consumer products and oilfield recovery. …

Thermodynamics of Micellar Lyotropic Liquid Crystals
… liquid crystals, giant-shape surfactants, and block polymers. The observation of these complex morphologies across different soft material classes stabilized by varying non-covalent interactions begs the question of universality in the principles that govern FK phase formation. The formation of …
