      Cover: Biaxial melt-drawing produces a high-performance poly(tetrafluoroethylene) (PTFE) membrane with excellent mechanical properties and superior transparency, compared to those of commercial PTFE sheet prepared by skiving technique. One of the possible applications of such transparent but robust PTFE is a stadium roof membrane, which state-of-art is composed of PTFE raw powder and glass fiber textiles, thus is cloudy white and difficult to recycle. Further details can be found in the article by Hiroki Uehara,* Yuuki Arase, Ken Suzuki, Yasumasa Yukawa, Yoshiaki Higuchi, Yasuhiko Matsuoka and Takeshi Yamanobe on page 669.

    1. Highly Transparent and Robust Poly(tetrafluoroethylene) Membrane Prepared by Biaxial Melt-Drawing (pages 669–673)

      Hiroki Uehara, Yuuki Arase, Ken Suzuki, Yasumasa Yukawa, Yoshiaki Higuchi, Yasuhiko Matsuoka and Takeshi Yamanobe

      Article first published online: 2 DEC 2013 | DOI: 10.1002/mame.201300310

      Biaxial melt-drawing produces a high-performance poly(tetrafluoroethylene) (PTFE) membrane with excellent mechanical properties and superior transparency. Unique two-step molding gave the better adhesion between the PTFE powder materials even with ultra-high molecular weight of 107. Such void-free film could be successfully biaxially drawn in the molten state. The resultant membrane exhibits high tensile strength of 120 MPa and high transparency of 8.5% haze.

    1. Contribution of High-shear Processing to the Compatibilization of (PP/EPR)/PE Ternary Blends (pages 674–688)

      Molka Louizi, Valérie Massardier and Philippe Cassagnau

      Article first published online: 24 NOV 2013 | DOI: 10.1002/mame.201300268

      Thumbnail image of graphical abstract

      This paper focuses on the compatibilization of high impact polypropylene/high density polyethylene (PP/EPR)/PE blends by using new high shear process. All (PP/EPR)/PE blends reveal a ‘PE/EPR’ dispersed phase formed by a core–shell structure, comprising a PE-rich core and an EPR outer shell, within PP matrix. Interestingly, the addition of ethylene-octene copolymer (EOC) to the processed blend at 600 rpm increases elongation at break and impact strength.

    2. Investigating the Crystal Growth Behavior of Biodegradable Polymer Blend Thin Films Using In Situ Atomic Force Microscopy (pages 689–697)

      Thomas Malwela and Suprakas Sinha Ray

      Article first published online: 28 OCT 2013 | DOI: 10.1002/mame.201300281

      Thumbnail image of graphical abstract

      This study reports on the understanding of crystal growth behavior of biodegradable polymer blends in a confined environment using in situ atomic force microscopy. Blends crystalline morphologies showed a relation to the blend ratio and temperatures at which they were crystallized. Crystallization by annealing generally favored the development of edge-on lamellae associated with homogeneous nucleation while crystallization from melt resulted in preferential growth of flat-on lamellae attributed to the heterogeneous nucleation.

    3. Microfluidic-Assisted Synthesis of Waterborne and Solvent-Free Urea-Crosslinked Polydimethylsiloxane Microparticles (pages 698–706)

      Adrien Dalmais, Christophe A. Serra, Zhenqi Chang, Michel Bouquey and René Muller

      Article first published online: 25 NOV 2013 | DOI: 10.1002/mame.201300279

      Thumbnail image of graphical abstract

      Double droplets of isocyanate core and dicarboxylic-acid-functionalized silicon oil or PDMS-amide prepolymer shell in water are produced by means of a capillary-based microfluidic process. This drop-in-drop stucture allows avoiding direct contact of isocyanate groups with water and results in the waterborne and solvent-free formation of urea-crosslinked PDMS microparticles having an extremly narrow size distribution.

    4. Synergistic Effect of Functionalized Silica Nanoparticles and a β-Nucleating Agent for the Improvement of the Mechanical Properties of a Propylene/Ethylene Random Copolymer (pages 707–721)

      Dimitrios G. Papageorgiou, George Vourlias, Dimitrios N. Bikiaris and Konstantinos Chrissafis

      Article first published online: 24 NOV 2013 | DOI: 10.1002/mame.201300320

      Thumbnail image of graphical abstract

      Surface modification of silica nanoparticles and the presence of a compatibilizer are simultaneously used to evaluate the effect on the dispersion of the nanoparticles and subsequently to the final properties of the nanocomposite samples. The results show that the quality of dispersion is improved, and the mechanical properties are significantly enhanced by this procedure.

    5. Flocculation Efficiency of Novel Amphiphilic Starch Derivatives: A Comparative Study (pages 722–728)

      Svetlana Y. Bratskaya, Sabine Genest, Katrin Petzold-Welcke, Thomas Heinze and Simona Schwarz

      Article first published online: 21 DEC 2013 | DOI: 10.1002/mame.201300277

      Thumbnail image of graphical abstract

      Adsorption and flocculation behavior of amphiphilic cationic starch derivatives (benzyl 2-hydroxypropyl-trimethylammonium starch chlorides) have been investigated for kaolin, calcium carbonate and silica. A moderate hydrophobic substitution leads to decreasing efficient flocculant doses and increasing flocculation window widths. High DS of hydrophobic moieties are effective only at significantly higher doses but in broader concentration ranges compared to cationic starch of the same DS.

    6. Encapsulated PDMS Microspheres with Reactive Handles (pages 729–738)

      Article first published online: 19 MAY 2014 | DOI: 10.1002/mame.201300319

      Vinyl-functionalized poly(dimethyl siloxane) (PDMS) microspheres with poly(methyl methacrylate) (PMMA) coatings were shown to be non-reactive in the presence of a hydride cross-linker at 60 °C.

    7. Electrical Conductive Adhesives Enhanced with High-Aspect-Ratio Silver Nanobelts (pages 739–747)

      Behnam Meschi Amoli, Ehsan Marzbanrad, Anming Hu, Y. Norman Zhou and Boxin Zhao

      Article first published online: 24 NOV 2013 | DOI: 10.1002/mame.201300295

      Thumbnail image of graphical abstract

      Novel high-aspect-ratio silver nanobelts (NBs) are used with typical silver micron flakes to develop advanced electrical conductive adhesive (ECA) composite materials. The synthesis of the NBs is based on self-assembly and room temperature joining of hexagonal and rectangular silver nanoparticles. Addition of a small amount of the Ag NBs into conventional ECAs results in a significant improvement of the electrical conductivity.

    8. Influence of Screw Profile Employed During Melt Mixing on the Micro-scale Dispersion of MWCNTs in Poly(propylene) (pages 748–756)

      Beatriz Mayoral, Graham Garrett and Tony McNally

      Article first published online: 27 DEC 2013 | DOI: 10.1002/mame.201300172

      MWCNT dispersion, distribution, and agglomerate size is determined by the screw profile employed during melt mixing of MWCNTs and PP in a twin-screw extruder.

    9. In Situ Reduction of Graphene Oxide in an Epoxy Resin Thermally Cured with Amine (pages 757–763)

      Marco Sangermano, Alberto Tagliaferro, David Foix, Micaela Castellino and Edvige Celasco

      Article first published online: 11 DEC 2013 | DOI: 10.1002/mame.201300286

      Thumbnail image of graphical abstract

      Electrically conductive epoxy resin composites are prepared by exploiting in situ reduction of graphene oxide (GOx) during the epoxy thermal curing in presence of amine. The optimum curing conditions were evaluated, and the efficiency of the reduction process of GOx induced by amine is confirmed by XPS analyses.
