Uniform Polyselenophene Block Copolymer Fiberlike Micelles and Block Co-micelles via Living Crystallization-Driven Self-Assembly

19-Jan-2018 | Emily L. Kynaston; Ali Nazemi; Liam R. MacFarlane; George R. Whittell; Charl F. J. Faul; Ian Manners, Macromolecules, 2018

We report the formation of near uniform block copolymer fiberlike micelles of controlled length with a crystalline polyselenophene core via the seeded growth process termed living crystallization-driven self-assembly (CDSA). Poly(3-decylselenophene)-block-poly(dimethylsiloxane) (P3DSe-b-PDMS) ...


Precision Synthesis of Polylactide-Based Thermoresponsive Block Copolymers via Successive Living Cationic Polymerization of Vinyl Ether and Ring-Opening Polymerization of Lactide

19-Jan-2018 | Yukiko Seki; Arihiro Kanazawa; Shokyoku Kanaoka; Tomoko Fujiwara; Sadahito Aoshima, Macromolecules, 2018

A new class of polylactide (PLA)-based block copolymers with thermoresponsive poly(vinyl ether) [poly(VE)] were precisely synthesized via successive living cationic polymerization of VE and ring-opening polymerization of lactide (LA). The synthetic route starts with precise end-functionalization ...


Testing the Universality of Entropic Segregation at Polymer Surfaces

19-Jan-2018 | P. Mahmoudi; W. S. R. Forrest; T. M. Beardsley; M. W. Matsen, Macromolecules, 2018

This study addresses entropic segregation effects at the surfaces of monodisperse and bidisperse melts. For the monodisperse melts, we focus on the segregation of chain ends to the surface, and for the bidisperse melts, we examine the segregation of short polymers to the surface. Universal shapes ...


Role of Thickness Confinement on Relaxations of the Fast Component in a Miscible A/B Blend

18-Jan-2018 | Ravi P. Sharma; Ban Xuan Dong; Peter F. Green, Macromolecules, 2018

Spatial compositional heterogeneity strongly influences the dynamics of the A and B components of bulk miscible blends. Its effects are especially apparent in mixtures, such as poly(vinyl methyl ether) (PVME)/polystyrene (PS), where there exist significant disparities between the component glass ...


Cyanostyrylthiophene-Based Ambipolar Conjugated Polymers: Synthesis, Properties, and Analyses of Backbone Fluorination Effect

18-Jan-2018 | Zuzhang Lin; Xiaotong Liu; Weifeng Zhang; Jianyao Huang; Qiang Wang; Keli Shi; Zhihui Chen; Yankai Zhou; Liping Wang ..., Macromolecules, 2018

Herein, we report the synthesis and characterization of a series of ambipolar cyanostyrylthiophene (CST)-based conjugated polymers without or with fluorine substituents, namely PD-CST, PD-3F-CST, PD-23F-CST, and PD-25F-CST. With the change of the number or incorporating position of fluorine ...


Surface Aligned Main-Chain Liquid Crystalline Elastomers: Tailored Properties by the Choice of Amine Chain Extenders

18-Jan-2018 | Hyeong-Ho Yoon; Dae-Yoon Kim; Kwang-Un Jeong; Suk-kyun Ahn, Macromolecules, 2018

A promising way to induce shape transformation in soft materials is via spatial variation in the orientation of the alignment of liquid crystalline elastomers (LCEs). Here, we improve the nascent thermomechanial shape transformation in main-chain LCEs prepared via aza-Michael addition reactions. ...


Copolymerization of Lactide and Cyclic Carbonate via Highly Stereoselective Catalysts To Modulate Copolymer Sequences

18-Jan-2018 | Xinli Liu; Xiufang Hua; Dongmei Cui, Macromolecules, 2018

The controlled ring-opening polymerizations of enantiopure (L-LA or D-LA) or racemic lactide (rac-LA) with achiral functionalized cyclic carbonates (TMCR) have been performed by using the aminobisphenolate yttrium and lutetium alkyl complexes or an organo-base catalyst DBU ...


Janus Particles Synthesis by Emulsion Interfacial Polymerization: Polystyrene as Seed or Beyond?

18-Jan-2018 | Jun-Bing Fan; Hong Liu; Yongyang Song; Zhen Luo; Zhongyuan Lu; Shutao Wang, Macromolecules, 2018

New strategies for synthesis of Janus particles are of essential importance in the advancement of material science and technology. However, it remains a great challenge to synthesize uniform Janus particles with controllable topological and chemical anisotropy. To overcome this challenge, we have ...


Topological Structure of Networks Formed from Symmetric Four-Arm Precursors

17-Jan-2018 | Tzyy-Shyang Lin; Rui Wang; Jeremiah A. Johnson; Bradley D. Olsen, Macromolecules, 2018

Gels formed by coupling two different four-arm star polymers lead to polymer networks with high strength and low spatial heterogeneity. However, like all real polymer networks, these materials contain topological defects which affect their properties. In this study, kinetic graph theory and Monte ...


Behavior of Weak Polyelectrolyte Brushes in Mixed Salt Solutions

17-Jan-2018 | Joshua D. Willott; Timothy J. Murdoch; Frans A. M. Leermakers; Wiebe M. de Vos, Macromolecules, 2018

Hydrophilic and hydrophobic weak polybasic brushes immersed in aqueous solutions of mixed salt counterions are considered using a mean-field numerical self-consistent field approach. On top of the solvent quality of the polymer, the counterion–solvent interactions are accounted for by ...
