A study of the poly(vinyl methyl ether) (PVME) segmental dynamics of bulk miscible blends of polystyrene (PS) and PVME reveals that while at high temperatures, T, there is evidence of a single α-relaxation process, at lower T, two separate dominant

The segmental dynamics of a low glass transition temperature Tg polymer under different conditions of morphological confinement are shown to manifest the influence of the frustration of the local “packing” of chain segments at interfaces of varyi

The influence of morphology on the dc conductivity σdc, the charge carrier density n and the out-of-plane mobilities μ were investigated in conjugated polymer films of poly(3-hexylthiophene) (P3HT) using impedance spectroscopy (IS). IS was used for

We demonstrate how to tailor the spatial distribution of gold nanoparticles (Au-NPs) of different sizes within polystyrene (PS) thin, supported, film hosts, thereby enabling the connection between the spatial distribution of Au-NPs within the polymer

We study the formation and organization of micelles, of polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) diblock copolymer chains, in thin film hosts composed of (1) blends of long and short chain polystyrenes, PSL and PSS, of degrees of polymerizatio

Many types of microsystems and microelectromechanical systems (MEMS) devices exhibit improved performance characteristics when operated below room temperature. However, designers rarely pair such devices with integrated cooling solutions because they

We recently showed that a suspension of micrometer-sized polystyrene (PS) particles in a PDMS liquid, mixed with small (1 wt %) amounts of a nanocage, sulfonated polyhedral oligomeric silsesquioxane (s-POSS), exhibited significant electrorheological

Regioregular poly(3-hexylthiophene) (RR-P3HT) is a widely used donor material for bulk heterojunction polymer solar cells. While much is known about the structure and properties of RR-P3HT films, important questions regarding hole mobilities in this

A lot of interesting and sophisticated examples of nanoparticle (NP) self-assembly (SA) are known. From both fundamental and technological standpoints, this field requires advancements in three principle directions: (a) understanding the mechanism an

An important challenge in the field of electrorheology is identifying low-viscosity fluids that would exhibit significant changes in viscosity, or a yield stress, upon the application of an external electric field. Our recent research showed that opt
