  1. Achieving high electric energy storage in a polymer nanocomposite at low filling ratios using a highly polarizable phthalocyanine interphase

    Owing to the high polarizability of a tetrameric metallophthalocyanine (TMPc) interface layer, 3-phase P(VDF-HFP)/BaTiO3@TMPc-PMMA composites exhibit high relative permittivity and thus high electric energy storage at a volume-filling ratio as low as about 5 vol %. Their relative permittivity fits well to the theoretical prediction of a 3-phase composite with a 0.20 interface ratio. Therefore, these 3-phase nanodielectrics are promising to be melt-processed into thin composite films for advanced dielectric applications.

    Confined crystallization of polymers within anodic aluminum oxide templates

    Within nanoporous anodic aluminum oxide (AAO) templates, polymer crystallization changes upon infiltration. When perfect infiltration is achieved, crystallization only occurs at very low temperatures that are close to vitrification and the overall crystallization kinetics becomes dominated by nucleation. Hence, the kinetics of crystallization changes from order 3–4 (usual in homopolymers) to order 1. The nucleation changes from heterogeneous to surface or homogeneous nucleation, although the latter is more difficult to achieve.

  3. Partially sulfonated ethylene–vinyl alcohol copolymer as new substrate for 3,4-ethylenedioxythiophene vapor phase polymerization

    Andrea Martinelli, Lucio D'Ilario, Iolanda Francolini, Antonella Piozzi and Elisa Pizzi

    Article first published online: 22 JUL 2014 | DOI: 10.1002/polb.23556

    A new biocompatible partially sulfonated ethylene vinyl alcohol copolymer (EVALS32) was synthesized and used as a supporting insulating matrix for EDOT vapour phase polymerization. This sulfonated polymer is able to provide stability to the PEDOT film and to suppress the oxidant crystallization without the use of specific additives. A homogeneous EVALS32–PEDOT composite film layered on a glass slide characterized by a good conductivity (1.6 × 102 S cm−1), optical transparency, surface smoothness, and stability in water was obtained.

  4. Stimuli-triggered phase transfer of polymer-inorganic hybrid hairy particles between two immiscible liquid phases

    Chunhui Bao, Jonathan M. Horton, Zhifeng Bai, Dejin Li, Timothy P. Lodge and Bin Zhao

    Polymer brush-grafted particles (hairy particles) that can undergo stimuli-induced phase transfer between two immiscible liquids are an intriguing class of hybrid materials. This review focuses on recent advances in this burgeoning area, starting with a discussion of the mechanism of particle transfer across a liquid-liquid interface and progressing to the phase transfer of hairy particles induced by various external stimuli including temperature, pH, and light. The applications in phase transfer catalysis are presented.

  5. Miscible blends of polylactide and poly(methyl methacrylate): Morphology, structure, and thermal behavior

    Maurizio Canetti, Adriana Cacciamani and Fabio Bertini

    Article first published online: 17 JUL 2014 | DOI: 10.1002/polb.23544

    Polylactide (PLA) is a biodegradable polymer that is synthesizable from renewable resources and has received great interest. Blending of polylactic acid with poly(methyl methacrylate) (PMMA) offers a valuable route to improve its thermal and mechanical behavior. The miscibility between the components is investigated using the dependence of the nucleation on composition and the polymer-polymer interactions calculated according to the melting point depression.
