    Classical principles on the phase separation of two immiscible polymeric components in a mutual solvent have been applied to tailor the optical properties of a polymer semiconductor in an insulating matrix. This approach allows controlling the solidification of the blend from solution, leading to new opportunities for the systematic manipulation of central photophysical characteristics of organic semiconductors for optoelectronic applications.

    Monte Carlo simulations were performed with block copolymers to explore the hole shrink problem for lithographic applications. The balance between the natural periodicity of the block copolymer and the diameter of the hole is the key factor to obtain a polymer cylinder that extends through the hole. When the system is out of the ideal conditions, changing the wall/polymer interaction, deforming the hole, adding homopolymers, and overfilling the holes provide a method for obtaining a polymer that extends through the hole.

    Understanding the physical aging process in glassy polymers is critical for materials with end-use applications below Tg. The current work utilizes three separate techniques to study physical aging in amorphous poly(ethylene furanoate) (PEF), which is a recently introduced engineering thermoplastic with enhanced properties compared to poly(ethylene terephthalate). Differential scanning calorimetry aging experiments are used in addition to density and oxygen transport measurements to investigate the free volume reduction mechanism for physical aging in PEF.

  4. Characterizing polymers with heterogeneous micro- and macrostructures

    A practical need exists for distinguishing between polymer samples with chains that have homogeneous and heterogeneous populations of micro- and macrostructures. A combination of high resolution13C-NMR to determine the types and amounts of constituent short-range microstructures, as well as dilute solution electrical birefringence or Kerr effect measurements to locate them along the polymer chains, may be able to achieve this macrostructural distinction.

  5. Control of mechanically activated polymersome fusion: Factors affecting fusion

    In this study, the environmental effects on the salt mediated, mechanically assisted fusion of polymer vesicles are investigated. Concentration of salt, as well as valence, is shown to heavily affect the fusion process, though the species of salt itself is of little concern. The results indicate an Arrhenius-like relationship between concentration, agitation speed, and the extent of fusion, uncovering reliable techniques by which the fusion process can be controlled.
