Autor: Glenn H. Fredrickson, Nicolas J. Treat, Edward J. Kramer, Phillip D. Hustad, Yingdong Luo, Damien Montarnal, Matthew D. Christianson, Craig J. Hawker
Publikováno v: ACS Macro Letters
ACS Macro Letters, Washington, D.C : American Chemical Society, 2015, 4 (12), pp.1332--1336
In addition to the traditional parameters of chi (χ) and degree of polymerization (N), we demonstrate that the segregation strength of a diblock copolymer can be increased by introduction of an ionic unit at the junction of the two blocks. Compared

Producing Small Domain Features Using Miktoarm Block Copolymers with Large Interaction Parameters
Autor: Weichao Shi, Glenn H. Fredrickson, Wei Li, Craig J. Hawker, Edward J. Kramer, Yuichi Tateishi
Publikováno v: ACS macro letters. 4(11)
We demonstrate that small domain features (∼13 nm) can be obtained in a series of polystyrene (PS) and poly(lactic acid) (PLA) block copolymers, PS–(PLA)2 and (PS)2–(PLA)2, that combine miktoarm molecular architectures with large interaction pa

ACS Nano, American Chemical Society, 2016, 10 (2), pp.2054-2062. ⟨10.1021/acsnano.5b06215⟩
Nanolayered lamellae are common structures in nanoscience and nanotechnology, but most are nearly symmetric in layer thickness. Here, we report on the structure and mechanics of highly asymmetric and thermodynamically stable soft--hard lamellar struc

Allyl-Terminated Polypropylene Macromonomers: A Route to Polyolefin Elastomers with Excellent Elastic Behavior
Autor: Toshihiko Sugano, Hisashi Ohtaki, Anne M. LaPointe, Fumihiko Shimizu, Edward J. Kramer, Giang D. Vo, Geoffrey W. Coates, Fanny Deplace, Glenn H. Fredrickson
Publikováno v: Macromolecules. 48:7489-7494
We report the design, synthesis, and physical/mechanical properties of graft copolymers containing semicrystalline polypropylene side chains and amorphous ethylene/α-olefin copolymer backbones. These materials, a new class of semicrystalline, polyol

Publikováno v: Macromolecules. 48:6606-6616
The characterization of the microstructure and molecular orientation is critical to understanding the performance of conjugated polymer semiconductors. In this work, near-edge X-ray absorption fine structure (NEXAFS) spectroscopy was used to study th

Phase Separated Morphology of Ferroelectric–Semiconductor Polymer Blends Probed by Synchrotron X-ray Methods
Autor: Eunhee Lim, Gregory M. Su, Edward J. Kramer, Michael L. Chabinyc
Publikováno v: Macromolecules. 48:5861-5867
Control of the domain size and morphology of ferroelectric-semiconductor polymer blend thin films is essential for producing working organic ferroelectric resistive switches that can be used for low-cost, flexible memory applications. However, improv
