The hydrazine grafted electrospun microfiber mat has been developed to reduce the precursor Pd2+ ions and provides support for the Pd nanoparticles with high accessibility and stability. The UV-grafting has been used to form a reducing polymer shell around porous poly(ether sulfone) microfibers. The uniformly hosted Pd nanoparticles in the polymer shell exhibit high catalytic activity in the redox reactions.
- Coassembly Modulated pH-Responsive Hydrogel for Dye Absorption and Release
Fang Wang, Wei Ji, Jinying Liu, Jiye He and Chuanliang Feng

An easy but effective approach to tune the pH-responsive property of supramolecular hydrogel by coassembly from small organic molecules is reported. This system works as a good absorbent of water-soluble cationic dyes and also a good carrier for its controlled release, and exemplifies a feasible shortcut to achieve new drug-delivery system.
- Promoting Endothelialization of Polymeric Cardiovascular Biomaterials

Blood compatibility remains one of the most pressing challenges in the biomaterials field. Developing biomaterials that foster a confluent and functional endothelium is one of the most promising strategies for addressing this challenge. In this article methods that have been explored for promoting the endothelialization of biomaterials and proposed future research directions are described.
- Room Temperature Self-Healing Methyl Phenyl Silicone Rubbers Based on the Metal–Ligand Cross-Link: Synthesis and Characterization
Dajiang Yu, Xinxin Zhao, Chuanjian Zhou, Chen Zhang and Shigui Zhao

Copper ions are introduced into polysiloxanes with pendent Schiff-base groups through metal–ligand coordination interaction. Coordination bonds which serve as cross-linking points endow the silicone rubbers excellent self-healing properties. Some samples can restore 87.0% strength after healing 1 h at 30 °C. The self-healing mechanism is also studied by cross-linking density analyzer.
- Versatile Mechanical and Thermoresponsive Properties of Macroporous Copolymer Gels
Chandra Sekhar Biswas, Qiao Wang, Massimiliano Galluzzi, Yuhang Wu, Sachin T. Navale, Bing Du and Florian J. Stadler
Version of Record online: 15 FEB 2017 | DOI: 10.1002/macp.201600554
Copolymer gels of versatile morphological, mechanical, thermoresponsive properties form by free radical polymerizations of different compositions of N-isopropylacrylamide and N-ethylacrylamide in 1:1 methanol–water (v/v) mixtures. Porosities and roughnesses of the gels gradually increase with the increase in N-isopropylacrylamide loading in the system. At the same time, Young's modulus and lower critical solution temperature gradually decrease with the increase in the same.
