- Stabilization of self-assembled microdroplets using short chain alcohols

Article first published online: 26 MAR 2015 | DOI: 10.1002/polb.23703
Producing honeycomb structure on the surface of polymer without trace of additive or changing the structure of polymer is a challenging task. In this paper, we show that using short chain alcohol in combination of breath-figure technique offers a simple and effective method for the fabrication of order porous surface. In a specific range of polymer and alcohol concentration, the surface of casted polymer is fully covered with micro water droplet, which after the complete solvent evaporation an order porous film is formed.

There has been limited success in the preparation of mechanically strong pH/temperature double responsive hydrogels. In this paper, nanocomposite (NC) hydrogels cross-linked by inorganic Laponite XLG were synthesized via in situ free radical polymerization of N,N-diethylacrylamide (DEA) and (2-dimethylamino) ethyl methacrylate (DMAEMA). The NC hydrogels displayed controlled transformation in optical transmittance and volume in response to temperature and pH. The compressive strength of swollen hydrogels was as high as 2219 kPa while compressive strain was 95%.
- dc Proton conductivity at low-frequency in Nafion conductivity spectrum probed by time-resolved SAXS measurements and impedance spectroscopy

Nafion has been extensively used as the electrolyte in proton exchange membrane fuel cells due to its high proton conductivity and diffusion coefficient. Numerous efforts have been focused on disentangling the intricate relation between the physical properties and morphology of perfluorosulfonate ionomers. Here, an additional dc proton conductivity at low frequencies in Nafion is identified by small-angle X-ray spectroscopy (SAXS) and impedance spectroscopy.
- A new periodic pattern with five-neighbored domain packing from ABC triblock terpolymer/B homopolymer blend
Yuki Izumi, Mutsuhiko Yamada, Atsushi Takano and Yushu Matsushita
Article first published online: 25 MAR 2015 | DOI: 10.1002/polb.23714
A new two-dimensional pattern is obtained from poly(isoprene-b-styrene-b-2-vinylpyridine) (ISP) triblock terpolymer/styrene homopolymer blend. The blends ISP/S(3k) and ISP/S(12k) showed a morphological transition from tetragonally packed cylinders (TPC) to double hexagonal structure (DHS) with hexagonally arrayed polyisoprene cylinders, each surrounded by six thin cylinders as satellites. This structure was confirmed to possess hexagonal symmetry with a larger unit cell than regular patterns ever known by X-ray diffraction experiment.
- Self-sustained entropy-driven flow in nano-confined polymer melts
Article first published online: 23 MAR 2015 | DOI: 10.1002/polb.23712
A MC simulation study of the Brownian motion of polymer chains in a melt confined in a periodically asymmetric channel of nanometric dimensions is presented, showing that the unexpected directed Brownian motion of polymers in confined geometries is of significant importance in the design and stabilization of platelet nanocomposites, which typically age over time under quiescent conditions.
