Phase behavior of repulsive polymer-tethered colloids.

We report molecular dynamics simulations of a system of repulsive, polymer-tethered colloidal particles. We use an explicit polymer model to explore how the length and the behavior of the polymer (ideal or self-avoiding) affect the ability of the particles to organize into ordered structures when the system is compressed to moderate volume fractions. We find a variety of different phases whose ...

Phase behavior of thermally responsive microgel colloids.

The phase behavior of poly-N-isopropylacrylamide (PNIPAM) nanoparticles dispersed in water is investigated using a thermodynamic perturbation theory combined with light-scattering and spectrometer measurements. It is shown how the volume transition of PNIPAM particles affects the interaction potential and determines a novel phase diagram that has not been observed in conventional colloids. Beca...

Effective Interactions, Structure, and Phase Behavior of Lightly Tethered Nanoparticles in Polymer Melts

We have generalized the microscopic polymer reference interaction site model (PRISM) theory to study the structure and phase behavior of polymer-tethered spherical nanoparticles in a dense homopolymer melt. In the absence of a polymer matrix, fluids of such hybrid nanoparticles show strong concentration fluctuations indicative of aggregate formation and/or a tendency for microphase separation a...

How do polydisperse repulsive colloids crystallize?

A modified version of the Gibbs-ensemble Monte-Carlo method reveals how polydisperse charged colloidal particles can build complex colloidal crystals. It provides general rules that are applicable to this fractionated crystallization that stems from size segregation. It explains the spontaneous formation of complex crystals with very large unit-cells in suspensions of nanoparticles with a broad...

A new class of tunable hypersonic phononic crystals based on polymer-tethered colloids

The design and engineering of hybrid materials exhibiting tailored phononic band gaps are fundamentally relevant to innovative material technologies in areas ranging from acoustics to thermo-optic devices. Phononic hybridization gaps, originating from the anti-crossing between local resonant and propagating modes, have attracted particular interest because of their relative robustness to struct...
