- Well-Defined Poly(ethylene glycol) Hydrogels with Enhanced Mechanical Performance Prepared by Thermally Induced Copper-Catalyzed Azide–Alkyne Cycloaddition
Ke Wen Li, Lian Cen, Chao Zhou, Ao Kai Zhang, Fang Yao, Lin Hua Tan, Li Qun Xu and Guo Dong Fu

Preparation of poly(ethylene glycol) (PEG)-based hydrogel via a facile thermally induced copper-catalyzed azide–alkyne cycloaddition reaction is demonstrated. The PEG-based hydrogels exhibit good mechanical performance with a tensile strength of 2.51 MPa. In vitro cytotoxicity and in vivo porcine subcutaneous implantation tests demonstrate that the as-synthesized hydrogel has a good biocompatibility.
- Quantifying Structural and Solid-State Viscoelastic Properties of Poly(propylene) (PP)/Poly(oxymethylene) (POM) Blend Films

The poly(propylene) (PP)/poly(oxymethylene) (POM) blends exhibit a characteristic immiscible matrix-droplet morphology and yield highly transparent films. Morphology and viscoelastic properties of films strongly depend on the POM amount into the blend structure. The creep tests and viscoelastic modeling represent that the short- and long-term deformations of PP films can be dramatically improved by introducing of POM, as a minor phase.
- Physical and Mechanical Modifications of Collagen Microfibers Using Ethanol-Based Dehydrating Conditions
Seon Young Bak, Sang Woo Lee, Kyung Sik Kim and Hyun Woo Kim
Version of Record online: 18 JUL 2016 | DOI: 10.1002/mame.201600119
Collagen microfibers with specific physical and mechanical properties are fabricated using the dehydration effect of ethanol. Despite the use of various exposure conditions, all fibers show similar cell attachment and its stable maintenance.

Richard A. Whiter, Yonatan Calahorra, Canlin Ou and Sohini Kar-Narayan
Version of Record online: 14 JUL 2016 | DOI: 10.1002/mame.201600135
“Self-poled” polyvinylidene fluoride-trifluoroethylene nanowires fabricated by solution wetting of nanoporous templates are measured with differential scanning calorimetry, Fourier transform IR spectroscopy, and dielectric permittivity measurements. These are quantitatively compared with measurements taken on electrically poled spin-coated films before and after subsequent depoling heat treatment to observe trends and determine the extent and nature of the self-poling effect in the nanowires as induced by the confined growth process.
- Sub-6 nm Thin Cross-Linked Dopamine Films with High Pressure Stability for Organic Solvent Nanofiltration
Liliana Pérez-Manríquez, Ali R. Behzad and Klaus-Viktor Peinemann
Version of Record online: 11 JUL 2016 | DOI: 10.1002/mame.201600107
Ultrathin mussel-inspired solvent resistant nanofiltration membranes fabricated by interfacial polymerization of dopamine and terephtaloyl chloride on a cross-linked polyacrylonitrile support exhibit excellent permeation and rejection performance in dimethylformamide. The thickness of the selective layer is ≈5 nm with a smooth surface, making this membrane attractive for industrial harsh solvent separation processes, as it is a simple and easy to scale up method.
