pH-induced shape-memory polymers
Abstract
A novel pH sensitive shape-memory polymer (SMP) is prepared by cross-linking the β-cyclodextrin modified alginate (β-CD-Alg) and diethylenetriamine modified alginate (DETA-Alg): The pH reversible β-CD-DETA inclusion complexes serve as a reversible phase, and the cross-linked alginate chains serve as a fixing phase. It is shown that this material can be processed into temporary shape as we needs at pH 11.5 and recover to its initial shape at pH 7. The recovery ratio and the fixity ratio were 95.7 ± 0.9% and 94.8 ± 1.1%, respectively. Furthermore, this material showed good degradability and biocompatibility. Because the shape transition pH value is quite close to that of our body fluid and this pH triggered shape-memory effect is convenient and safe to use, this material has a high potential for medical application.

In the citing paper
“Chemo-responsive SMPs, pH-, redox- and moisture- and solvent-induced, are one of the barely studied systems in the literature [57-59].”

In the citing paper
“On the molecular level, such systems were dual-component, similar to the heating-responsive SMPs. Alginate (Alg) chains cross-linked with calcium cations served as the fixation domain, while the switching domain was constituted of b -cyclodextrin ( b -CD) and diethylenetriamine (DETA) when introduced in the Alg matrix.”

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.
