Abstract

The polymer chain conformation under confinement and the morphology of the nanohybrid materials are investigated in hydrophilic polymer/layered silicate nanocomposites. A series of poly(ethylene oxide)/sodium montmorillonite hybrids were synthesized utilizing melt intercalation with compositions covering the complete range from pure polymer to pure clay. Intercalated nanocomposites with mono- and bilayers of PEO chains are obtained in all cases. The intercalated chains as well as the ones adsorbed on the outer surface of the clay particles remain purely amorphous; their conformation, however, exhibits different characteristics from those of the amorphous neat polymer melt. It is only for compositions where a large amount of excess polymer exists outside the completely full galleries that the polymer crystallinity is recovered.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Xc is nearly constant for PEO/SiO2 and PEO/Na+-MMT nanocomposites with low filler content and begins to decrease above a certain concentration (10-30 vol% SiO2 depending on nanoparticle size or 10 vol% Na+-MMT).

    “The X c is nearly constant for PEO/SiO 2 and PEO/layered sodium montmorillonite (Na + -MMT) nanocomposites with low filler content and it begins to decrease above a certain concentration (10-30 vol% SiO 2 depending on the size of nanoparticles or 10 vol% Na + -MMT).”

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.
