We report an investigation of the influence of block copolymer architectures on formation of nanophases in epoxy thermosets via reactioninduced microphase separation approach. Toward this end, three binary block copolymers composed of polystyrene (PS) and poly(ε-caprolactone) (PCL) were synthesized via the combination of ring-opening polymerization (ROP) and atomic transfer radical polymerizati...

2014 A theoretical analysis of microphase separation in binary micelles is presented. We consider micelles consisting of two kinds of diblock copolymers such that the micellar corona contains two chemically distinct block types (A and B). Both intramicellar and intermicellar processes may occur. We focus on intermicellar segregation occurring after a quench yielding complete intramicellar micro...

Self-assembly of block copolymers into well-defined, ordered arrangements of chemically distinct domains is a reliable strategy for preparing tailored nanostructures. Microphase separation results from the system, minimizing repulsive interactions between dissimilar blocks and maximizing attractive interactions between similar blocks. Supramolecular methods have also achieved this separation by...

The microscopic polymer reference interaction site model theory is generalized and applied to study intermolecular pair correlation functions and collective structure factors of dense solutions and melts of spherical nanoparticles carrying a single tethered chain. The complex interplay of entropy (translational, conformational, and packing) and enthalpy (particle-particle attraction) leads to d...

Microphase separated block copolymers consisting of an amorphous poly~ethylene oxide! ~PEO!-based polymer covalently bound to a second polymer offer a highly attractive avenue to achieving both dimensional stability and high ionic conductivity in polymer electrolytes for solid-state rechargeable lithium batteries. However, due to the strong thermodynamic incompatibility typically found for most...

Polyanhydride copolymers based on 1,6-bis(p-carboxyphenoxy)hexane (CPH) and sebacic acid (SA) are bioerodible, semicrystalline polymers that have been used for drug delivery. In addition to their semicrystallinity, these materials also exhibit microphase separation in the amorphous phase. This complex phase behavior, combined with the disparity in the erosion rates of the two different chemical...

Herein, we have reported a para -fluoro thiol click reaction allowing control of the microphase separation and dielectric properties poly(pentafluorostyrene- b -acrylic acid) copolymers.
