- Preparation of Core–Shell Nanofibers with Selectively Localized CNTs from Shish Kebab-like Hierarchical Composite Micelles
Chang-Lei Liu, Mei-Jia Wang, Gang Wu, Jiao You, Si-Chong Chen, Ya Liu and Yu-Zhong Wang
Article first published online: 22 JUL 2014 | DOI: 10.1002/marc.201400261
A novel and facile bottom-up strategy is described for preparing core–shell nanofibers with selectively localized carbon nanotubes by using hierarchical composite micelles of crystalline-coil copolymer and CNTs as the building blocks.
- Hg2+-Induced In Situ Generated Radical Cation of (S)-BINOL-Based Polymer for Highly Enantioselective Recognition of Phenylalaninol
Jiemin Jiao, Fei Li, Shuwei Zhang, Yiwu Quan, Wenhua Zheng, Yixiang Cheng and Chengjian Zhu
Article first published online: 22 JUL 2014 | DOI: 10.1002/marc.201400248
The (S)-BINOL-based polymer sensor is designed and synthesized. Polymer sensor can exhibit highly selective and sensitive enantioselective recognition effect towards (L)-phenylalaninol by Hg2+-induced in situ generated radical cation of oligomeric aniline moiety.
- Solvent Vapor Annealing: An Efficient Approach for Inscribing Secondary Nanostructures onto Electrospun Fibers
Jianzhao Liu, Adam J. P. Bauer and Bingbing Li
Article first published online: 19 JUL 2014 | DOI: 10.1002/marc.201400274
This study, for the first time, demonstrates that the solvent vapor annealing (SVA) method can be utilized to introduce structural hierarchy to poly(ε-caprolactone) (PCL)-based fibers. The acetone vapor can delocalize amorphous chains and redeposit them onto the existing crystal edges, leading to hierarchically structured fibers. This facile approach provides new insight into the design and fabrication of hierarchical polymeric materials.
- Bacterial Cellulose Nanopaper as Reinforcement for Polylactide Composites: Renewable Thermoplastic NanoPaPreg
Thanit Montrikittiphant, Min Tang, Koon-Yang Lee, Charlotte K. Williams and Alexander Bismarck
Article first published online: 19 JUL 2014 | DOI: 10.1002/marc.201400181
High-performance renewable bacterial cellulose nanopaper reinforced polylactide laminates are produced using the PaPreg manufacturing concept. NanoPaPregs with tensile stiffness and strength of 6.5 GPa and 125 MPa, respectively, are obtained. The image shows a scanning electron micrograph of a fractured nanoPaPreg (the scale bar represents 5 μm).
- Microporous Polymeric 3D Scaffolds Templated by the Layer-by-Layer Self-Assembly
Thomas Paulraj, Natalia Feoktistova, Natalia Velk, Katja Uhlig, Claus Duschl and Dmitry Volodkin
Article first published online: 19 JUL 2014 | DOI: 10.1002/marc.201400253
3D hollow polymeric scaffolds composed of interconnected microspheres are fabricated by a combination of microfluidics and template (sacrificial CaCO3 cores) assistant layer-by-layer assembly. Microsphere size defined by the template size governs fibroblasts adhesion to the scaffold. The microspheres are loaded with protein, thus opening perspectives for controlled and localized delivery in tissue engineering applications.
