Zinc ion uniquely induced triple shape memory effect of dipole-dipole reinforced ultra-high strength hydrogels
Abstract
In this study, we demonstrate that dipole-dipole interaction can be employed to not only tremendously enhance the mechanical properties of hydrogel, but also impart the gel to an amazing ability to memorize two temporary shapes. Cross-linked hydrogels synthesized by copolymerization of acrylonitrile, a dipole-dipole containing monomer and hydrophilic comonomer are shown to exhibit triple shape memory (SM) triggered by the dynamic association and dissociation of dipole-dipole pairing between cynao groups uniquely responding to zinc ion species and concentration. This approach contributes to design and fabrication of novel SM hydrogels in a distinct way from conventional SM materials.

ZnO SMCs include imidazole-zinc ion coordinated shape-memory hydrogel, triple-shape-memory poly(acrylonitrile 2-methacryloyloxyethyl phosphorylcholine) from dipole-dipole-zinc ion coordination, epoxy-based SMP containing metallosupramolecular unit, and ZnO NRs in PU matrix.
“They are containing imidazole-zinc ion for the production of coordinated shapememory hydrogel [174], triple-shape-memory poly(acrylonitrile 2-methacryloyloxyethyl phosphorylcholine) from dipoledipole-zinc ion coordination [175] or epoxy-based SMP containing metallosupramolecular unit formed by coordinating 2,6-bis( N -methyl-benzimidazolyl)-pyridine ligands to zinc di[bis(trifluoromethylsulfonyl)-”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
