Self-healing poly(N-isopropylacrylamide) hydrogels
European Polymer Journal, 2015 Abstract Substitution the covalently crosslinked polymer chains by supramolecular ones is a promising strategy to design self-healing hydrogels. Approaches for the synthesis of supramolecular poly(N-isopropylacrylamide) (PNIPAAm) hydrogels with the ability to self-heal are rare because of the bulky side groups of the polymer hindering formation of ...

The Importance of Excess Poly(N-isopropylacrylamide) for the Aggregation of Poly(N-isopropylacrylamide)-Coated Gold Nanoparticles [PDF]
ACS Nano, 2016 Thermoresponsive materials are generating significant interest on account of the sharp and tunable temperature deswelling transition of the polymer chain. Such materials have shown promise in drug delivery devices, sensing systems, and self-assembly. Incorporation of nanoparticles (NPs), typically through covalent attachment of the polymer chains to ...
