True Chemical Structure of Double Network Hydrogels
Abstract
We elucidate why the anomalous high strength of double network gels is obtained when the second network is polymerized without any cross-linkers. We have synthesized truly independent -DN gels (named “ t -DN” gels), which do not have any covalent bonds between the first and the second networks, and showed that the t -DN gels cannot be toughened by the un-cross-linked second network. It means that the high strength of usual DN gels without the cross-linker of the second network is actually achieved by the inter connection between the two networks through covalent bonds (so usual DN gels were named “ c -DN” gels). Further, we found that the t -DN gels become stronger than the c -DN gels when the second network is loosely cross-linked. As the t -DN gels have a more simple structure than the c -DN gels, we expect that the toughening mechanism of DN gels will be clarified by studying the t -DN gels in the future.

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.
