  1. Super Hydrogen and Helium Barrier with Polyelectolyte Nanobrick Wall Thin Film

    Ping Tzeng, Elva L. Lugo, Garret D. Mai, Benjamin A. Wilhite and Jaime C. Grunlan

    Article first published online: 27 NOV 2014 | DOI: 10.1002/marc.201400559

    A 122 nm layer-by-layer (LbL) coating on polystyrene is shown to lower both hydrogen and helium permeability three orders of magnitude against bare polystyrene. This highly flexible coating represents the first demonstration of an LbL-deposited film with low hydrogen and helium permeability and is an ideal candidate for several packaging and protection applications.

  2. Strategic Modulation of the Photonic Properties of Conjugated Organometallic Pt–Ir Polymers Exhibiting Hybrid CT-Excited States

    Ahmed M. Soliman, Eli Zysman-Colman and Pierre D. Harvey

    Article first published online: 27 NOV 2014 | DOI: 10.1002/marc.201400542

    The replacement of X = H by F conveniently induces a blue shift of the absorption and emission bands arising from the hybrid-excited CT states compensating for the red shifting effect due to conjugation, and also decreases the emission quantum yields and lifetimes at 298 and 77 K.

  3. Thermorheological and Mechanical Properties of Copolymers of Lactide, Isosorbide, and Different Phthalic Acids

    Zucong Zhang, Hans Rytger Kricheldorf and Christian Friedrich

    Article first published online: 27 NOV 2014 | DOI: 10.1002/marc.201400489

    The mechanical properties of selected copolymer samples are characterized by tensile tests and compared to a commercial poly(methyl methacrylate) (PMMA) sample (=100.000 g mol−1). In this case, nonlinear mixing rules are found regarding the Young's modulus in dependence of different phthalates contents.

  4. Temperature-Triggered Phase Separation of a Hydrophilic Resilin-Like Polypeptide

    Linqing Li, Tianzhi Luo and Kristi L. Kiick

    Article first published online: 26 NOV 2014 | DOI: 10.1002/marc.201400521

    Hydrophilic resilin-like polypeptides: solutions of recombinant resilin-like polypeptides exhibit phase separation and form nanoparticles with increasing temperatures. The transition temperature and particles sizes can be modulated via salt identity, ionic strength, pH, and denaturants.

  5. Star-Pseudopolyrotaxane Organized in Nanoplatelets for Poly(ε-caprolactone)-Based Nanofibrous Scaffolds with Enhanced Surface Reactivity

    Murielle Oster, Anne Hébraud, Sébastien Gallet, Alain Lapp, Eric Pollet, Luc Avérous and Guy Schlatter

    Article first published online: 25 NOV 2014 | DOI: 10.1002/marc.201400533

    Thumbnail image of graphical abstract

    Star pseudopolyrotaxanes of α-cyclodextrin and star poly(ε-caprolactone) form stable nanoplatelet micelles in dimethyl sulf­oxide and are subsequently processed by coaxial electrospinning to obtain poly(ε-caprolactone):star pseudopolyrotaxanes core:shell fibers. The star pseudopolyrotaxanes shell ensures the presence of α-cyclodextrin hydroxyl functions on the fiber surface allowing efficient postfunctionalization while keeping intact the entire morphology of the fibrous scaffold in solvents.
