We use numerical and analytical models to investigate polymer films formed by tethering chains to flat surfaces and immersing the system in a poor solvent. Since the ends of the chains are immobilized on the surface, the polymers avoid the unfavorable solvent by clustering together into aggregates, or pinned micelles, on the surface. These micelles have a uniform size and spacing and form a distinct...
The ability to form blends of polymers offers the opportunity of creating a new class of materials with enhanced properties. In addition to the polymer components, recent advances in nanoengineering have resulted in the development of nanosized inorganic particles that can be used to improve the properties of the blend, such as the flammability and the mechanical properties. While traditional methods...
The interfacial properties of a homopolymer (polybutadiene (PB)) and a terpolymer (brominated poly(isobutylene-co-p-methylstyrene) (BIMS)) are reported. Neutron reflectivity was used to study the interfacial structure. The results were complemented by scanning transmission X-ray microscopy and atomic force microscopy, which were used to probe the morphology of these binary blends. Our results show...
