- Shape Memory Particles Capable of Controlled Geometric and Chemical Asymmetry made from Aliphatic Polyesters
Sarah M. Brosnan, Anne-Martine S. Jackson, Yapei Wang and Valerie Sheares Ashby
Article first published online: 24 JUL 2014 | DOI: 10.1002/marc.201400199
A novel technique for creating monodisperse shape memory particles is reported. A soft mold is used to uniformly deform particles of complex shapes to other well-defined shapes, harvest them without aggressive solvents or heat, and then return them to their original shapes upon heating above a preselected triggering temperature. Particles are synthesized from a broad range of materials and additionally are capable of both chemical and physical asymmetry.
- 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).
