The trade-off between processability and performance in commercial ionomers

Strong ionic interactions between macromolecular chains improve physical and mechanical properties beyond those of the base polymer. Associating groups strongly affect the rheological properties and therefore the polymer processing window.

Quantifying the errors due to overfilling for Newtonian fluids in rotational rheometry

The errors on rheological measurements due to overfilling of Newtonian fluids using parallel plate and cone-plate setups in rotational rheometry are quantified. Overfilled sample causes an additional drag force, thereby increasing the measured …

Phase behavior and dynamics of Pluronic®-based additives in semidilute solutions of poly(ethersulfone) and poly(N-vinyl pyrrolidone): rheological and dynamic light scattering experiments

The phase behavior and dynamical properties of a pristine Pluronic® F127 and a Pluronic®-based multiblock copolymer, respectively, in semidilute solutions of poly(ethersulfone) (PESU) and poly(N-vinyl pyrrolidone) (PVP) in N-methyl-2-pyrrolidone …

Investigating the dynamics of droplet breakup in a microfluidic cross-slot device for characterizing the extensional properties of weakly-viscoelastic fluids

A microfluidic device, deemed the Plateau-Rayleigh microfluidic extensional rheometer (PRIMER), is presented that uses a cross-slot geometry to observe a two-phase droplet-breakup event in which the viscoelastic fluid is in the dispersed (or …

Rheology of bacterial suspensions under confinement

As a paradigmatic model of active fluids, bacterial suspensions show intriguing rheological responses drastically different from their counterpart colloidal suspensions. Although the flow of bulk bacterial suspensions has been extensively studied …
