- Synthesis and Characterization of Functional Thienyl-Phosphine Microporous Polymers for Carbon Dioxide Capture

Phosphorus-functionalized microporous polymers are designed by introducing polar organic groups and electron-rich heterocycles to obtain attractive carbon dioxide capacity. The polymers show high isosteric heat and relative high gas selectivity. Additionally, the polymer containing P=O groups shows greater gas uptake than that containing P=S groups at the same pressure and temperature.
- Transient Absorption Spectroscopy Studies on Polythiophene–Fullerene Bulk Heterojunction Organic Blend Films Sensitized with a Low-Bandgap Polymer

Polythiophene–fullerene bulk heterojunction ternary blend films are investigated by transient absorption spectroscopy. Hole transfer from PCPDTBT-positive polarons to P3HT in the blend film can be visualized. This process evolves within 140 ps and is discussed with respect to the proposed charge-generation mechanisms.
- Facile Synthesis of Free-Standing Polymer Brush Films Based on a Colorless Polydopamine Thin Layer

A free-standing polymer brush film with tailored thickness based on a colorless polydopamine thin layer is prepared and characterized. Free-standing films of thicknesses ≈16–75 nm are controlled by simply changing the atom transfer radical polymerization (ATRP) reaction time.
- Monolithic Nanoporous Crystalline Aerogels
Christophe Daniel, Simona Longo, Rosa Ricciardi, Ernesto Reverchon and Gaetano Guerra
Article first published online: 12 JUN 2013 | DOI: 10.1002/marc.201300260
Monolithic aerogels can be obtained by drying physical gels formed by linear uncross-linked polymers. Particularly relevant are aerogels whose cross-linking knots are nanoporous crystalline, which beside disordered amorphous micropores (typical of all aerogels and shown by scanning electron microscopy) also present all identical crystalline nanopores.
- Forming of Polymer Nanofibers by a Pressurised Gyration Process
Suntharavathanan Mahalingam and Mohan Edirisinghe
Article first published online: 10 JUN 2013 | DOI: 10.1002/marc.201300339
A method is invented for the preparation of polymer nanofibers. The size distribution of the fibers can be tailored to suit. Using calculations where necessary, an explanation is given of the physical phenomenon of the new process which is also very competitive in comparison with the existing conventional methods, in particular yield and fiber size control.
