From Homogeneous to Heterogeneous Nucleation of Chain Molecules under Nanoscopic Cylindrical Confinement

Woo, Euntaek, Huh, June, Jeong, Young Gyu, Shin, Kyusoon·2007·Physical Review Letters

Abstract

The crystallization of monodisperse linear polyethylene confined in nanoporous alumina is investigated with the calorimetric measurements. We observe a drastic change in crystallization behavior, specifically nucleation, with a decrease in the pore diameter. Crystallization in relatively larger pores with the diameters of 62 and 110 nm occurs at lower temperatures within a very narrow range, whereas crystallization in smaller pores with diameters of 15-48 nm occurs at a higher and broad range of temperatures. Nucleation and crystallization kinetics in nanopores is discussed based on classical nucleation theory as well as the Avrami theory.

  • Within 110 nm AAO templates, the PE crystallization temperature dropped to 80 °C.

    “Within 110 nm templates, the T c dropped to 80 °C (peak B).”

  • For 48 nm AAO, another broad PE peak appeared at about 80-110 °C, and this higher Tc shifted to lower temperatures with decreasing AAO diameter.

    “Another broad peak appeared at ∼80-110 °C for 48 nm AAO.This higher T c shifted towards lower temperatures with decreasing AAO diameter.”

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.
