  1. On The Role of Wetting, Structure Width, and Flow Characteristics in Polymer Replication on Micro- and Nanoscale

    Christian Rytka, Nadia Opara, Nis Korsgaard Andersen, Per Magnus Kristiansen and Andreas Neyer

    Article first published online: 12 FEB 2016 | DOI: 10.1002/mame.201500350

    The dewetting potential (integrated spreading coefficient) of a polymer is proposed as a simple rationale for estimation of the replicability of functional micro- and nanostructures by injection molding. A good correlation is shown with the replicated height covering the microand nanorange on brass and fluorocarbon modified nickel. Additionally, a parabolic relationship is demonstrated between filled height and width.

  2. Recent Progress on the Design and Applications of Polysaccharide-Based Graft Copolymer Hydrogels as Adsorbents for Wastewater Purification

    Hemant Mittal, Suprakas Sinha Ray and Masami Okamoto

    Article first published online: 11 FEB 2016 | DOI: 10.1002/mame.201500399

    The chemical and physical properties of gum polysaccharides, different methods of graft copolymerization, and the use of graft copolymer gum-polysaccharide-based hydrogels are reported for the removal of toxic heavy metal cations and synthetic dyes from aqueous solutions.

  3. High-Performance Flame-Retarded Polyamide-6 Composite Fabricated by Chain Extension

    Alvianto Wirasaputra, Lijun Zheng, Shumei Liu, Yanchao Yuan and Jianqing Zhao

    Article first published online: 11 FEB 2016 | DOI: 10.1002/mame.201500357

    Phosphorus-containing diepoxide compound (DEP) is novelly synthesized and is used to simultaneously enhance the flame retardancy and mechanical properties of polyamide–6/aluminum diethylphosphinate composite. The feasible amelioration effect is originated from the synergistic flame retardant effect and chain extension reaction. The flammability, forced combustibility, and mechanical properties of the modified composite are measured to verify the improvement.

  4. Thermally Stable Honeycomb-Patterned Porous Films of a Poly(L-lactic acid) and Poly(D-lactic acid) Stereo Complex Prepared Using the Breath Figure Technique

    Hiroya Abe, Yutaro Hirai and Hiroshi Yabu

    Article first published online: 10 FEB 2016 | DOI: 10.1002/mame.201500474

    Porous films of stereo-complexed poly(lactic acid)s sufficiently stabile to withstand autoclave sterilization are successfully prepared by using the breath figure technique. Surface patterning of porous stereo-complexed poly(lactic acid)s are also achieved by UV-O3 treatment.

  5. Explaining the Difference Between Real Part and Virtual Design of 3D Printed Porous Polymer at the Microstructural Level

    Omar Ben Hassana, Sofiane Guessasma, Sofiane Belhabib and Hedi Nouri

    Article first published online: 10 FEB 2016 | DOI: 10.1002/mame.201500360

    Reverse engineering approach for porous polymer design shows mismatch between virtual and real parts. Thanks to 3D microstructural interpretation, guidance towards optimal material design is bounded by the ability to control both amount of process-induced porosity and residual support material in fused deposition modeling.
