    1. Bis(trifluoromethanesulfonyl)imide-Type Ionic Liquids as Excellent Antistatic Agents for Polyurethanes (pages 794–798)

      Takuya Iwata, Akiko Tsurumaki, Saori Tajima and Hiroyuki Ohno

      Version of Record online: 9 DEC 2013 | DOI: 10.1002/mame.201300333

      Thumbnail image of graphical abstract

      Surface resistivity (ρs) of polyurethane (PU) films is reduced by the addition of bis(trifluoromethanesulfonyl)imide type ionic liquids (ILs). This effect is attributed to ionic conductivity derived from the low glass transition temperature of both the polyether network in the PU films and the ILs. Additionally, the reduced ρs of PU films is retained even after methanol washing.

    2. Single Polymer Composites of Poly(Butylene Terephthalate) Microfibrils Loaded with Carbon Nanotubes Exhibiting Electrical Conductivity and Improved Mechanical Properties (pages 799–806)

      Stoyko Fakirov, M. Zillur Rahman, Petra Pötschke and Debes Bhattacharyya

      Version of Record online: 16 DEC 2013 | DOI: 10.1002/mame.201300322

      Thumbnail image of graphical abstract

      Applying the concept of microfibrillar (MF) composites, microfibrils of poly(butylene terephthalate) (PBT) with 5 wt% carbon nanotubes (CNT) are prepared by extraction of polypropylene (PP) from drawn PP/PBT blends and shaped into single polymer composites (SPCs). The SPCs show superior mechanical performance with up to 300–600% improvement in modulus and tensile strength as compared to neat isotropic PBT.

    1. Preparation of Rice Husk-Based Medium Density Fiberboards: Effects of pH Modification on Mechanical and Tribological Performance (pages 807–813)

      Susana Vargas, J. Rogelio Rodriquez, Haley E. Hagg Lobland, Katarzyna Piechowicz and Witold Brostow

      Version of Record online: 14 JAN 2014 | DOI: 10.1002/mame.201300341

      Rice husk is a major waste byproduct of global rice paddy production. Disposal is difficult, costly, and poses environmental threat. Rice-husk-based medium density fiberboard, prepared with solvent-free polyurethane, utilizes the husk in a widely used construction material. Aspects of synthesis along with evaluation of mechanical and tribological behavior are characterized and discussed.

    2. Influence of Melt Viscosity on the Structure and Properties of Electrically Conductive Nanocomposites Produced by Masterbatch Process (pages 814–824)

      Stefano Besco, Alessandra Lorenzetti, Denis Hrelja, Carlo Boaretti, Martina Roso, Dino Ferri and Michele Modesti

      Version of Record online: 20 JAN 2014 | DOI: 10.1002/mame.201300336

      Ultra-low molecular weight polypropylene grade can be successfully used for the production of multi-walled carbon nanotube(MWCNT)-based masterbatches but in order to get the optimal dispersion in the final compound the molecular weight of the diluting polymer cannot be too high as to not mix effectively with the masterbatch resin.

    3. Up-Scaling of Melt-Spun LDH/HDPE Nanocomposites (pages 825–833)

      Burak Kutlu, Juliane Meinl, Andreas Leuteritz, Harald Brünig, Sven Wießner and Gert Heinrich

      Version of Record online: 12 FEB 2014 | DOI: 10.1002/mame.201300212

      Layered double hydroxide (LDH) can be incorporated into melt-spun polyethylene fibers if it is initially organomodified and well dispersed in the matrix. LDH/polyethylene nanocomposites show high melt-spinnability, which can serve large-scale fiber production purposes. Moreover, preparation of bicomponent fibers, where the sheath is the composite and the core is the polyethylene, is also possible.

    4. Monomers for Adhesive Polymers, 14 Synthesis and Radical Polymerization of 4-[11-(Acryloyl-methyl-amino)-undecyloxy]-phthalic Acid and {10-[1,3-Bis(methacrylamido)-propoxy]-decyloxy}-phthalic Acid (pages 834–842)

      Iris Lamparth, Urs K. Fischer, Juraj Pavlinec, Angela Kleinova and Norbert Moszner

      Version of Record online: 20 JAN 2014 | DOI: 10.1002/mame.201300332

      Two polymerizable phthalic acid derivatives are synthesized via etherification of the methoxymethy (MOM)-ester of 4-hydroxy-phthalic acid with the corresponding bromo-alkyl-(meth)acrylamides. Owing to their enhanced hydrolytic stability, they represent a viable alternative to methacrylate-based phthalic acid derivatives, which are established adhesive monomers in self-etching dental formulations.

    5. Macroporous Polyolefin Membranes from Dicyclopentadiene High Internal Phase Emulsions: Preparation and Morphology Tuning (pages 843–850)

      Sebastijan Kovačič, Florian Preishuber-Pflügl and Christian Slugovc

      Version of Record online: 12 FEB 2014 | DOI: 10.1002/mame.201300400

      Thumbnail image of graphical abstract

      High internal phase emulsions (HIPEs) are used to prepare porous polydicyclopentadiene membranes with thicknesses from 50 up to 200 μm. Owing to the cross-linked structure of the polydicyclopentadiene, these porous membranes are insoluble in many solvents but can swell and uptake more than 1 500 wt% of the solvent without losing porosity upon de-swelling and drying.

    6. Extensional Rheological Investigation of Biodegradable Polylactide-Nanographite Platelet Composites via Constitutive Equation Modeling (pages 851–868)

      Esmaeil Narimissa, Rahul K. Gupta, Nhol Kao, Duc A. Nguyen and Sati N. Bhattacharya

      Version of Record online: 24 FEB 2014 | DOI: 10.1002/mame.201300382

      Thumbnail image of graphical abstract

      This research investigates the extensional rheological properties of polylactide/nanographite plateletscomposites through the application of the Papanastasiou–Scriven–Macosko–Luo–Tanner (PSMLT) form of Kaye–Bernstein–Kearsley–Zapas (K-BKZ) constitutive model of extensional deformation. Moreover, a systematic analysis of the shear rheological behaviors (linear and nonlinear) of the composites is explored in this study.

    7. Achieving Electrical Conductive Tracks by Laser Treatment of non-Conductive Polypropylene/Polycarbonate Blends Filled with MWCNTs (pages 869–877)

      Marco Liebscher, Beate Krause, Petra Pötschke, Andrea Barz, Jens Bliedtner, Michael Möhwald and Alexander Letzsch

      Version of Record online: 26 FEB 2014 | DOI: 10.1002/mame.201300377

      Thumbnail image of graphical abstract

      Electrical conductive tracks can be created by local laser beam irradiation of injection molded plates consisting of immiscible two-component polymer blends, in which the proportion between polycarbonate and polypropylene is varied. The nanotube localizes in PC and after laser treatment an accumulation of MWCNTs directly at the surface in the created laser lines can be observed.

    8. Tape Extrusion of Heterogeneous Polymer Blends: Polymer Films with Highly Oriented Nanoribbons, Structural–Optical Property, and Anisotropic Mechanical Strength (pages 878–884)

      Long Wang, Hongxia Wang, Lianfang Feng and Tong Lin

      Version of Record online: 11 DEC 2013 | DOI: 10.1002/mame.201300329

      Thumbnail image of graphical abstract

      Well-oriented polymer nanoribbons can be prepared by a simple, scalable tape extrusion process from a phase-separated polymer blend and subsequent dissolution of the continuous phase from the film. The nanoribbon-containing polymer film also shows interesting structural–optical properties and anisotropic mechanical strength.

    9. Mechanical Properties of Thermoplastic Protein From Bloodmeal and Polyester Blends (pages 885–895)

      K. I. Ku Marsilla and Casparus J. R. Verbeek

      Version of Record online: 27 FEB 2014 | DOI: 10.1002/mame.201300396

      Thumbnail image of graphical abstract

      The amount and type of compatibilizer used is critical when blending polybutylene succinate with bloodmeal-based thermoplastic protein. The blend's morphology shows a smaller particle size of the dispersed phase for blends at optimal tensile properties while plastic deformation was observed for samples where elongation at break was optimal.
