Homogeneous Crystallization of Poly(Ethylene Oxide) Confined to Droplets: The Dependence of the Crystal Nucleation Rate on Length Scale and Temperature

Massa, Michael V., Dalnoki-Veress, Kari·2004·Physical Review Letters

Abstract

We present a study of homogeneous nucleation in polymer crystallization. Crystal nucleation is observed within discrete droplets of poly(ethylene oxide) that are formed by the dewetting of a thin film. The samples provide an ensemble of impurity-free droplets, with length scales that can easily be measured. Droplet crystallization is found in two distinct temperature regimes corresponding to homogeneous and heterogeneous nucleation. Here we focus on homogeneous nucleation and show that the nucleation rate scales with the volume of the crystallizable domain, indicating that we are observing homogeneous nucleation in the bulk of the droplets. In addition, the dependence of the nucleation rate on temperature is consistent with classical nucleation theory.

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

  • Dalnoki-Veress et al. pointed out that the homogeneous nucleation mechanism does not depend on molecular weight or chain length and that the formation of a nucleus is only influenced by its immediate surroundings.

    “Dalnoki-Veress et al. have pointed out that homogeneous nucleation mech-anism does not depend on the molecular weight or chain length and the formation of a nucleus is only influenced by its immediate surroundings [ 316 , 317 ].”

  • The probability of a homogeneous nucleus to be formed upon spontaneous aggregation of chain segments is proportional to the volume of undercooled polymer, whereas surface-induced nucleation depends on the system area.

    “In fact, the probability of a homogeneous nucleus to be formed upon spontaneous aggregation of chain segments is proportional to the volume of undercooled polymer.On the other hand, a dependence on the system area is found for the case of surface-induced nucleation.”

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.
