- Uniform Polyaniline Nanotubes Formation via Frozen Polymerization and Application for Oxygen Reduction Reactions
FuKe Wang, Zhijuan Wang, Maureen B. H. Tana and Chaobin He

A frozen polymerization technique is reported, affording control of both the diffusion of the monomers and polymer chain packing to achieve highly crystalline, uniform polyaniline nanotubes, which are facilely converted into oxygen reduction reaction catalytic nitrogen doped carbon nanotubes.

A simple strategy of remodeling of polymer networks and the subsequent crosslinking process (RsC process) is proposed, for preparation of uniform alginate microbeads with ultrahigh density, up to ≈38 wt%, via size reduction to 34% of the initial size. Such microbeads could be applied to prepare various alginate hydrogels of high density, with tailored mechanical properties.
- Self-assembled UCST-Type Micelles as Potential Drug Carriers for Cancer Therapeutics
Gang Huang, Hao Li, Shi-Ting Feng, Xiaoqiong Li, Guoquan Tong, Jie Liu, Changyun Quan, Qing Jiang, Chao Zhang and Ziping Li
Article first published online: 23 FEB 2015 | DOI: 10.1002/macp.201400546
UCST-type micelles that disrupt at elevated temperatures are reported. The thermal response of the micelles are tunable. Above the UCST the micelles burst, releasing any encapsulated material. Such micelles may find potential applications as nanocarriers of anticancer drugs.
- A Novel Near-IR Effective Pyrene-Based Donor–Acceptor Electrochrome
Emre Sefer, Serife O. Hacioglu, Murat Tonga, Levent Toppare, Ali Cirpan and Sermet Koyuncu
Article first published online: 23 FEB 2015 | DOI: 10.1002/macp.201400584
A novel donor–acceptor electrochromic material (poly-3HTP) containing a pyrene subunit is directly deposited onto an indium tin oxide (ITO)/glass surface via an electrochemical process. The polymer film exhibits a multielectrochromic feature, a strong near-infrared absorption at the oxidized state with an optical contrast of 88% (at 1800 nm), a very fast response time of 0.5 s and fast switching times, and long-term stability.
- Synthesis of Block Copolymers Based on Polyethylene by Thermally Induced Controlled Radical Polymerization Using Mn2(CO)10

A novel polymerization mechanism transformation strategy—combining catalyzed chain growth polymerization and thermally induced controlled free radical polymerization—is successfully applied for the synthesis of polyethylene-b-poly(methyl methacrylate) block copolymers with relatively low dispersities. The end group functionality of the block copolymer is confirmed by using polyethylene-b-poly(methyl methacrylate) as a macroinitiator for the polymerization of styrene.
