  1. Self-Regulation in Flow-Induced Structure Formation of Polypropylene

    Peter C. Roozemond, Martin van Drongelen, Zhe Ma, Anne B. Spoelstra, Daniel Hermida-Merino and Gerrit W. M. Peters

    Subjecting a polymer melt below its melting point to high shear stress can create strongly oriented crystal structures. It is shown that, in channel flow, this crystalline structure does not depend on spatial coordinate or flow condition due to a self-regulating effect, as evidenced by the crystallization kinetics.

  2. Chitosan-PEG Hydrogel with Sol–Gel Transition Triggerable by Multiple External Stimuli

    Ching Ting Tsao, Meng Hsuan Hsiao, Mengying Y. Zhang, Sheeny Lan Levengood and Miqin Zhang

    Article first published online: 17 DEC 2014 | DOI: 10.1002/marc.201400586

    Smart hydrogels play an increasingly important role in biomedical applications, since materials that are both biocompatible and multi-stimuli-responsive are highly desirable. A biocompartible hydrogel is introduced that exhibits a controllable multi-stimuli-responsive property. The effect of multiple environmental variables on the sol–gel transition of the hydrogel is evaluated and the underlying mechanisms of polymer gelation are discussed.

  3. The Effect of Stabilizer on the Mechanical Response of Double-Emulsion-Templated Polymersomes

    Woo-Sik Jang, Seung Chul Park, Miju Kim, Junsang Doh, Daeyeon Lee and Daniel A. Hammer

    Article first published online: 16 DEC 2014 | DOI: 10.1002/marc.201400472

    Stabilizers are used to increase the stability of polymersomes templated by double emulsion. The comprehensive experimental study of effect of stabilizer on the mechanical response of double-emulsion-templated polymersomes membrane using micropipette aspiration is presented. Stabilizer-free polymersomes show purely elastic behavior regardless of aging while polymersomes with stabilizer exhibit in­elastic behavior in the early stage of solvent removal.

  4. Surface-Initiated Anionic Polymerization of [1]Silaferrocenophanes for the Preparation of Colloidal Preceramic Materials

    Johannes Elbert, Haiko Didzoleit, Claudia Fasel, Emanuel Ionescu, Ralf Riedel, Bernd Stühn and Markus Gallei

    Article first published online: 15 DEC 2014 | DOI: 10.1002/marc.201400581

    Surface-initiated ring-opening polymerization of [1]silaferrocenophane from the surface of organic particles leads to novel metallopolymer core/shell architectures. The ferrocene-containing particle shell features the capability of conversion into iron silicide ceramic materials with ferromagnetic properties after thermal treatment.
