Templated Self‐Assembly of Block Copolymers: Top‐Down Helps Bottom‐Up
TL;DR: Templated self-assembly of block copolymers as discussed by the authors provides a path towards the rational design of hierarchical device structures with periodic features that cover several length scales, and provides a promising route to control bottom-up self-organization processes through top-down lithographic templates.

Ultra-high-strength polyethylene filaments by solution spinning/drawing
Paul Smith,PJ Piet Lemstra +1 more
TL;DR: In this paper, the influence of the draw ratio on the mechanical and thermal properties of polyethylene fibres was investigated, and it was found that the tensile strength tended to approach an upper limit at high draw ratios.

The spherulitic and lamellar morphology of melt-crystallized isotactic polypropylene
D.R. Norton,A. Keller +1 more
TL;DR: In this paper, the basic morphology of melt-crystallized isotactic polypropylene (iPP) was investigated using both optical and electron microscopy, and specific correlations were obtained between the structural entities on all scales of the structure hierarchy.
Journal ArticleDOI
The nucleation, growth, structure and epitaxy of thin surface films
TL;DR: A review of the evidence available on the mechanism of growth and the structure of thin deposited films is given in this article, where the main attention is devoted to the growth of metals onto single crystal substrates, particularly those formed by the evaporation technique.
Journal ArticleDOI
The molecular origin of lamellar branching in the α (monoclinic) form of isotactic polypropylene
Bernard Lotz,J. C. Wittmann +1 more
TL;DR: In this paper, the specific lamellar branching characteristic of isotactic polypropylene (iPP) in its α monoclinic modification, first investigated in detail by Khoury, is analyzed in molecular terms on the basis of the geometrical and structural models of Padden and Keith and of Binsbergen and de Lange, respectively.
Journal ArticleDOI
Polymer decoration: The orientation of polymer folds as revealed by the crystallization of polymer vapors
TL;DR: In this paper, a new technique of decorating the fold surface of polymer crystals is described, similar in methodology to gold decoration, but makes use of vapors of crystallizable polymers, principally polyethylene, as decorating material.
