Thermo-responsive gels that absorb moisture and ooze water
Nature Communications, 2018 Most smart hydrogels are used in their wet state and determination of their phase transition behaviour in the dried state is lacking. Here the authors investigate the thermo-responsive behaviour of an interpenetrating polymer network gel comprising of ...

Carbodiimide‐Driven Toughening of Interpenetrated Polymer Networks
Angewandte Chemie, 2023 AbstractRecent work has demonstrated that temporary crosslinks in polymer networks generated by chemical “fuels” afford materials with large, transient changes in their mechanical properties. This can be accomplished in carboxylic‐acid‐functionalized polymer hydrogels using carbodiimides, which generate anhydride crosslinks with lifetimes on the order ...
