We find that the method must only be applied within a narrow parameter window, and that even then, unreliable values may be obtained. (C) 2010 American Institute of Physics. [doi:10.1063/1.3504222]“
“In

this study, we present a new fabrication process for proton exchange membranes based on inorganic/organic nanocomposite using in situ surface grafting reaction and reactive dispersion of silica nanoparticles in the presence of reactive dispersant, urethane acrylate nonionomer (UAN). Through in situ surface grafting reaction of BMS-777607 datasheet silica nanoparticles, urethane acrylates were chemically introduced on the surface of silica nanoparticles, which were dispersed in DMSO solutions containing UAN and sodium styrene sulfonate (NaSS). After urethane linkage and copolymerization of NaSS, UAN and urethane acrylate moieties of silica nanoparticles, the solutions FDA approved Drug Library were converted to silica nanoparticle-dispersed proton exchange membranes where silica particles were chemically connected with organic polymer chains. 5.89-29.45 wt % of silica nanoparticles could be dispersed and incorporated in polymer membranes, which were confirmed by transmittance electron microscopy (TEM) measurement. On varying weight % of silica nanoparticles dispersed within the membranes, water uptake and oxidative stability of nanocomposite membranes were largely changed, but membranes

showed almost the same proton conductivity (greater than 10(-2) S cm(-1)). At 5.89 wt % of silica nanoparticles, nanocomposite membranes showed the lowest water uptake and excellent oxidative stability compared to the sulfonated polyimide membranes fabricated by us.

“This paper presents an approach of “”film separation”" and “”transfer”" to fabricating functional films or devices on polymeric substrates. For either a ferroelectric La-doped Pb(Zr, Ti)O(3), PLZT thin film Stattic mouse or a ZnO thin film, using laser lift-off (LLO),

film separation from the transparent rigid substrate (sapphire or glass) was achieved. The film transfer to a polymeric receptor substrate was obtained by laminating the polymeric substrate on the film stack prior to LLO. The introduction of a sacrificial layer between the film and the substrate mostly resolved concerns to induce damages during LLO. Electrical testing of the films before and after LLO demonstrated the film properties on the original substrate were satisfactorily retained even for the transferred films on the polymeric substrate.

“Poly(butylene succinate) (PBSu)/fumed silica nanocomposites were prepared in situ by condensation polymerization. TEM micrographs verified that the dispersion of the nanoparticles was homogeneous in the PBSu matrix, while some small agglomerates were also formed at a higher SiO(2) content.
