Sergei Sheiko of North Carolina at Chapel Hill will first delve into the nuanced properties of polymer networks, including their modulus, strain-stiffening behavior, and swelling tendencies, all of ...

First, they submerged the samples in a hydrogel solution containing small compounds that behave as liquid until they link up into polymer chains that absorb water and congeal into a gel. These ...

In laser swelling, a focused infrared laser is beamed at plastics used for eyeglasses. The laser, which functions as a local heat source, excites water molecules present inside the polymer.

THE problem of the swelling of gels has been the subject of a great deal of research, and still there does not appear to be any clear agreement between the views of different workers regarding the ...

Polymer electrolyte membrane (PEM ... water by a sponge is restricted when the sponge is confined between two plates. The energy required for swelling (or shrinking) of the membrane depends on the ...

However, polymer networks offer a unique solution ... viologen allows precise control over electron transfer by inducing swelling or shrinking at a constant temperature. Redox changes in the ...

A new study has unveiled the potential of hydrogen-bonding crosslinked supramolecular polymer materials derived from N-acryloyl glycinamide (NAGA).
