Novel Shape‐Memory Polymer with Two Transition Temperatures
Abstract
Summary: This communication describes a novel kind of PMMA‐PEG semi‐interpenetrating network (semi‐IPN) which shows excellent shape‐memory behavior at two transition temperatures, the Tm of the PEG crystal and the Tg of the semi‐IPN. Based on a reversible order‐disorder transition of the crystals below and above the Tm of PEG, and the large difference in storage modulus below and above the Tg of the semi‐IPN, the polymer has a recovery ratio of 91 and 99%, respectively.

Liu et al. designed a novel PMMA-PEG semi-IPN prepared by radical homopolymerization and cross-linking in the presence of linear PEG.
“In 2005 a double dual-SME was described by Liu et al. They designed a novel kind of poly(methyl methacrylate)-poly(ethylene glycol) (PMMA-PEG) semi-IPN prepared by radical homopolymerization and cross-linking in the presence of linear PEG [60].”

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.
