Journal ArticleDOI
Fluctuations, conformational asymmetry and block copolymer phase behaviour
Frank S. Bates,Mark F. Schulz,Ashish K. Khandpur,Stephan Förster,Jeffrey H. Rosedale,Kristoffer Almdal,Kell Mortensen +6 more
TL;DR: In this paper, phase behavior near the order-disorder transition (ODT) of 58 model hydrocarbon diblock copolymers, representing four different systems, is summarized, and six distinct ordered-state microstructures are reported, including hexagonally modulated lamellae (HML), hexagonalally perforated layers (HPL), and a bicontinuous cubic morphology with Iatextdecoration:overline-3d space group symmetry.
Journal ArticleDOI
Epitaxial relationship for hexagonal-to-cubic phase transition in a block copolymer mixture.
TL;DR: These results identify block copolymers as model compounds for investigating the thermodynamics and dynamics of complex "soft" condensed matter.
Journal ArticleDOI
Phase behavior of polystyrene-poly(2-vinylpyridine) diblock copolymers
Mark F. Schulz,Ashish K. Khandpur,Frank S. Bates,Kristoffer Almdal,Kell Mortensen,Damian A. Hajduk,Damian A. Hajduk,Sol M. Gruner +7 more
TL;DR: In this article, the phase behavior of a series of polystyrene−poly(2-vinylpyridine) diblock copolymers (Mw ∼ 20,000 g/mol) using dynamic mechanical spectroscopy, transmission electron microscopy, smallangle neutron scattering, and small-angle X-ray scattering was characterized.
Journal ArticleDOI
Phase Behavior of Pure Diblocks and Binary Diblock Blends of Poly(ethylene)−Poly(ethylethylene)
Jin Zhao,Biswaroop Majumdar,Mark F. Schulz,Frank S. Bates,Kristoffer Almdal,Kell Mortensen,Damian A. Hajduk,Damian A. Hajduk,Sol M. Gruner +8 more
TL;DR: In this paper, the phase behavior of a series of model poly(ethylene)−poly(ethylethylene) (PE−PEE) diblock copolymers with poly(methylene) block volume fractions (fPE) ranging from 0.25 to 0.46 was determined.
Journal ArticleDOI
Correlation of binary polyolefin phase behavior with statistical segment length asymmetry
TL;DR: In this article, the segment-segment interaction parameter χ is reported as a function of temperature for four pairs of polyolefin based on polyethylene, poly(ethylenepropylene), poly(ethylethylene) and poly (ethylene-co-ethylthylene), and a correlation between the magnitude of χ and the statistical segment length asymmetry was established.
