Since the first publications of large amplitude oscillatory shear (LAOS) responses of
polymeric materials in the 1960s, different approaches have been developed to express …

Comb and bottlebrush polymers present a wide range of rheological and mechanical
properties that can be controlled through their molecular characteristics, such as the …

Highly branched “bottlebrush” polymers are a class of macromolecules characterized by
side chains that are densely grafted from a backbone that is typically linear. Their unique …

Single polymer dynamics offers a powerful approach to study molecular-level interactions
and dynamic microstructure in materials. Direct visualization of single polymer chains has …

Monodisperse comb polystyrenes (comb-PS) with loosely to densely grafted architectures
up to loosely grafted bottlebrush structures were synthesized via anionic polymerization …

The POM–POM architecture is the simplest yet defined branched architecture, showing both
strain hardening in elongation and strain softening in shear. The molecular structure …

The recyclability of opaque PET, which contains TiO2 nanoparticles, has not been as well-
studied as that of transparent PET. The objective of this work is to recycle post-consumer …

We present a systematic investigation of the linear viscoelasticity and nonlinear start-up
shear flow response of a well-characterized H-polystyrene, an archetype branched polymer …

Strain hardening of long-chain branched polymers in elongational flow occurs due to the
stretch of the backbone chain between branch points. With an increasing number of side …

Rheological properties highly impact the foaming behavior of polymers, as a high melt
strength and low shear viscosity support cell expansion by reducing cell coalescence and …
