- Fabrication of Nanoscale Patternable Films of Silk Fibroin Using Benign Solvents
Alessio Bucciarelli, Ramendra K. Pal, Devid Maniglio, Alberto Quaranta, Viviana Mulloni, Antonella Motta and Vamsi K. Yadavalli
Version of Record online: 20 APR 2017 | DOI: 10.1002/mame.201700110
Formic acid is presented as a sustainable solvent for silk fibroin and fibroin “resists,” for micro- and nanoscale applications such as next generation biocompatible optical devices. Mechanically robust, homogeneous, smooth, and transparent thin and ultrathin films are formed which can be used for high-resolution photopatterning using benchtop lithographic techniques.
- Evaluation of Difunctional Vinylcyclopropanes as Reactive Diluents for the Development of Low-Shrinkage Composites
Yohann Catel, Pascal Fässler, Urs Fischer, Christian Gorsche, Sebastian Schörpf, Sven Tauscher, Robert Liska and Norbert Moszner
Version of Record online: 19 APR 2017 | DOI: 10.1002/mame.201700021
The synthesis of four new low viscosity vinylcyclopropanes is described. Photopolymerization kinetics and curing characteristics of these monomers are studied by means of photo-differential scanning calorimeter and real-time near-infrared photorheology. Composites based on the newly synthesized vinylcyclopropanes exhibit significantly lower polymerization shrinkage and shrinkage stress than a corresponding dimethacrylate-based material.
- Novel Proton Conducting Membranes from the Combination of Sulfonated Polymers of Polyetheretherketones and Polyphosphazenes Doped with Sulfonated Single-Walled Carbon Nanotubes
Tianwei Luo, Hulin Xu, Zhong Li, Shuitao Gao, Amina Ouadah, Zeyu Zhang, Yanxia Zhang, Fang Wang, Chaojun Jing and Changjin Zhu
Version of Record online: 12 APR 2017 | DOI: 10.1002/mame.201700095
Membranes based on polyetheretherketone and polyphosphazenes are prepared by cross-linking reaction. Morphological study by the transmission electron microscopy (TEM) indicates that well-separated nanophase and interconnected ionic channel form in the composite membrane, which can account for the remarkable proton transfer.
- Exceptionally Reinforced Polymer Nanocomposites via Incorporated Surface Porosity on Graphene Oxide Sheets
Hyo Won Kim, Ji Hye Yoon, Kyle M. Diederichsen, Jae Eun Shin, Byung Min Yoo, Bryan D. McCloskey and Ho Bum Park
Version of Record online: 12 APR 2017 | DOI: 10.1002/mame.201700039
Highly fortified and stretchable polymer nanocomposites are successfully prepared by a simple solution blending process. For outstanding compatibility with thermoset polyurethane, graphene oxide (GO) is modified by growing silica nanoparticles on the GO surface. The prepared polymer nanocomposites improve the Young's modulus and tensile strength with only a small reduction of elongation at break.
- Fluid-Induced Alignment of Carbon Nanofibers in Polymer Fibers
Mingchang Lu, Farrokh Sharifi, Nicole N. Hashemi and Reza Montazami
Version of Record online: 11 APR 2017 | DOI: 10.1002/mame.201600544
Carbon nanofibers are successfully incorporated and aligned within polycaprolactone (PCL) microfibers using shear forces in a microfluidic channel. The composite flexible microfibers exhibit significantly increased electrical conductivity and tensile strength compared to pure PCL microfibers.
