Crystalline Morphology of Homopolymers and Block Copolymers
Abstract
The crystallization of homopolymers yields a hierarchical structure in polymer materials, which substantially controls their physical properties. Therefore, the crystalline morphology of homopolymers has been one of the important research subjects in polymer science. This chapter summarizes the crystalline morphology formed in homopolymers, which is usually explained in many textbooks of polymer science. It describes more complicated morphology, that is, the crystalline morphology of block copolymers. The chapter also describes the characteristics of the crystal structure, lamellar morphology, and spherulite structure from the viewpoint of interrelation among them, and also experimental methods to quantitatively analyze these morphologies. The lamellar morphology formed in miscible blends is usually observed using small-angle X-ray scattering (SAXS) because its typical repeating distance is in the order of ˜10nm. The spherulite is a sphere-shaped superstructure, and usually observed when crystalline polymers are quenched or slowly cooled from a homogeneous melt into low temperatures.

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.
