  1. Influence of side chain linker length on ion-transport properties of polymeric ionic liquids

    We present simulation results exploring the mobility of counterions in polymerized-single-ion ionic liquid (IL) electrolytes with varying side chain linker length. We demonstrate that the diffusivity increases with increasing linker length. We rationalize this phenomenon to be a consequence of an increasing frequency of intermolecular hopping events for longer linkers, which is inversely correlated to the distance between intermolecular polymer–ionic moieties. Such a mechanism is supported by evidence that ion mobility in polymeric ILs of varying linker lengths is correlated to the lifetime of ion associations.

    In the ternary mixture of PLLA/PVAc/PEO, phase separation produces PLLA-rich phase and PVAc/PEO mixed phase. In the former, tiny crystals and amorphous matrix act as the fixed phase and reversible phase, respectively. In the latter, PEO plays the role of pore-forming agent and results in the connected nanopores and interpenetrated channels upon water etching.

  3. High diffusion barrier and piezoelectric nanocomposites based on polyvinylidene fluoride-trifluoroethylene copolymer and hydrophobized clay

    The addition of hydrophobized clay particles to a piezoelectric fluorinated polymer and annealing of the resulting exfoliated composites considerably decrease the gas permeability of the material and the associated activation energy. Moreover, the piezoelectric coefficient d33 of the exfoliated and annealed composites is 20–40% higher than that of the as-cast polymer. Such remarkable combination of gas barrier and piezoelectricity is of interest for creating self-sensing liners for high-pressure gas storage vessels.

  4. High strength reversible adhesive closures

    Closures such as buttons, clasps, and zippers play important roles in commercial items such as clothing and hand bags. Despite many recent advances in reversible adhesive technology, these methods have not been updated. Here, we introduce adhesive closures based on scalable reversible adhesives, inspired by the climbing ability of the gecko. These adhesives can support large adhesive strengths, greatly exceeding the performance of current closure technologies.

  5. Thickness dependence of structural relaxation in spin-cast polynorbornene films with high glass transition temperatures (>613 K)

    Elizabeth A. Lewis and Bryan D. Vogt

    Version of Record online: 5 SEP 2017 | DOI: 10.1002/polb.24434

    Polynorbornene films with high Tg's exhibit rapid aging (∼10−3) even at temperatures 300 K below their bulk Tg. For thin films, the thickness change was nonmonotonic during isothermal aging at lower temperatures. This phenomenon was attributed to the chain conformations that develop in the thin films on casting.
