Self-healing poly(N-isopropylacrylamide) hydrogels
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]
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 ...

Characterization of Ball-milled Poly(Nisopropylacrylamide) Nanogels
Poly(N-isopropylacrylamide) (PNIPAM) hydrogels are one of the most commonly studied thermoresponsive biomaterials. In this work, we investigate ball milling as a method of producing PNIPAM nanogels and confirm that the temperature responsiveness is ...

Water flow in poly(N-isopropylacrylamide) gels
Friction between a polymer network of poly(N-isopropylacrylamide) gels and solvent water was investigated. The gel was mechanically constrained in a glass capillary at gelation, and hydrostatic pressure was directly applied to the cross section of the cylinder.
