Confined crystallization of polymeric materials

Michell, Rose Mary, Müller, Alejandro J.·2016·Progress in Polymer Science

Abstract

The interest in confined crystallization has greatly increased with the development and progress of nanotechnology applications. Polymeric confined crystallization has been studied in droplets, ultrathin films , nanolayers , nanostructures from solutions, blends, copolymers , polymers infiltrated within AAO templates and nanocomposites . As confinement increases, the crystallization temperature first decreases, then splits into several fractions (i.e., fractionated crystallization) and finally occurs in one step at the maximum possible supercooling, near the glass transition temperature . Two factors are responsible for these effects: (a) a change in nucleation mechanism , from heterogeneous nucleation to surface nucleation (or in extreme cases, homogeneous nucleation), (b) the dependence of the crystallization temperature on the volume or the surface (or interphase) of the crystallizable micro or nanodomains. The melting point also decreases with confinement but to a lesser degree. A preferential orientation of polymeric crystals is generally induced by one or two dimensional confinement. Avrami indexes decrease with confinement until values of 1 (or even lower) are achieved in the limit of isolated domains, as the material approaches a first order crystallization kinetics . This type of kinetics reflects that nucleation is the rate determining step in the overall crystallization of ideally confined polymers.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Fractionated crystallization has been reported for strongly segregated block copolymers, as well as for weakly segregated or miscible block copolymers.

    “fractionated crystallization [ 39 , 85 , 86 , 91 , 93 , 97 ] has been reported for strongly segregated block copolymers, as well as for weakly segregated or miscible block copolymers”

    From Fractionated crystallization in semicrystalline polymers (2021) · cites this paper as [97]

  • Some MDs will have the most active heterogeneities, other populations of MDs could have less active heterogeneities needing higher undercooling, and some MDs will be clean, in which case crystallization occurs via surface or homogeneous nucleation.

    “Some of the MDs will have the most active heterogeneities (like the bulk polymer), other populations of MDs could have less active heterogeneities which need higher undercooling for crystallization, and finally some MDs will be clean (without heterogeneities), in which case the crystallization occurs via surface or homogeneous nucleation”

  • The fractionated crystallization phenomenon has been explained based on the absence of sufficiently active heterogeneities in every MD.

    “The fractionated crystallization phenomenon has been explained based on the absence of sufficiently active heterogeneities in every MD [ 39 , 85 , 91 , 97 ].”

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.
