Hot Paper: Molecular theory of weak polyelectrolyte thin films

Read for free until 25 April>>

The recently developed Molecular Theory of Weak Polyelectrolyte Gels was extended to include hydrogel films in this Hot Paper. The theory was used to study the behaviour of a weak polyelectrolyte gel constrained by a surface, to understand the structure and properties and how they differ when the gel is in contact with a water solution as compared to a hard wall. This information is important as thin hydrogel films are excellent candidates for the development of micro- and nano-sized applications requiring fast and stable stimuli-responsive materials.
