Polymer networks are complex systems consisting of molecular components. Whereas the
properties of the individual components are typically well understood by most chemists …

Taking a small step away from Newtonian fluid behavior creates an explosion in the range of
possibilities. Non-Newtonian fluid properties can achieve diverse flow objectives, but the …

Non-linear mechanical responses observed in networks of many biopolymers such as pectin
are important for their functioning as biological systems. Additionally, pectins derived from …

Associative polysaccharides, decorated by multiple but short, side-chain hydrophobic
stickers (typically 6–20 carbon long) that associate in solution, are used as thickeners for an …

Injectable poly (ethylene glycol)(PEG)-based hydrogels were reversibly cross-linked through
thia-conjugate addition bonds and demonstrated to shear thicken at low shear rates. Cross …

Polymers bearing associative groups can exhibit fascinating rheological behaviors. A
modified version of the Rouse model, which is originally used in block copolymers and …

Linear viscoelasticity (LVE) and nonlinear elongational behavior are examined for a series
of entangled ionomers based on poly (hexyl methacrylate) as the backbone and sodium …

The Liesegang pattern is a beautiful natural anisotropic patterning phenomenon observed in
rocks and sandstones. This study reveals that the Liesegang pattern can induce nonlinear …

Chemical crosslinking, physical associating, and filler filling play vital roles in nonlinear
responses of rubbers under large amplitude oscillatory shear (LAOS). Herein, a systematical …

Spiropyran molecular switches, in conjunction with transition metal ions, are shown to
operate as reversible polymer cross-linkers. Solutions containing a spiropyran …
