      There have been fascinating breakthroughs in organic thermoelectric (TE) materials/composites during the last several years, some of which are reaching the marketplace. On page 737 (DOI: 10.1002/polb.23482), Qinglin Jiang, Congcong Liu, Jingkun Xu, Baoyang Lu, Haijun Song, Hui Shi, Yuanyuan Yao, and Long Zhang present a simple and economical method for preparing organic TE composites by directly writing poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) solutions on common paper. Improved TE performances, especially the doubled Seebeck coefficient, are achieved. The composite film displays excellent flexibility, a light weight, and soaking stability in water. This new approach can be used to develop high-performance organic TE materials and shows great potential in the large-scale production of organic electronics.

      Superhydrophobic surfaces are currently in high demand because of their potential use in self-cleaning windows, anticorrosion, antiicing, and antibacterial applications. On page 782 (DOI: 10.1002/polb.23483), Janwa El-Maiss, Thierry Darmanin, Elisabeth Taffin de Givenchy, Sonia Amigoni, Julian Eastoe, Masanobu Sagiska, and Frédéric Guittard show that poly(3,4-propylenedioxythiophene) derivatives with fluorocarbon and hydrocarbon chains can be used to prepare superhydrophobic surfaces with good oleophobic properties. The surfaces are prepared by electrodeposition using cyclic voltammetry.

      Paper has been applied to cutting edge research such as organic photodiodes, organic thin-film transistors, and active matrix displays. In this work, a novel strategy using paper as an effective substrate to prepare thermoelectric materials. Free-standing poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/paper composite films are conveniently prepared via one direct-write step, showing excellent flexibility, light weight, soaking stability in water, and great potential in large-scale production. This new approach can be developed for the preparation of high-performance and flexible thermoelectric materials.

      Thin films composed of polycyclohexane (PCHE), zinc(II)−5,10,15,20-tetra-(2-naphthyl)porphyrin (ZnTNpP), and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) blends are prepared to investigate their potential for the controlled self-assembly of a porphyrin/fullerene donor–acceptor complex. The compatibilities in these blends have a significant effect on the dispersion of the ZnTNpP/PCBM donor–acceptor complex. This concept may be applied to various combinations of porphyrin/fullerene systems in polymer thin film solar cells to achieve excellent performance.

    1. Characterization of two- and three-photon absorption of polyfluorene derivatives (pages 747–754)

      Fluorene-based polymers are promising materials for electronic devices, but their nonlinear optical properties have only recently been intensively researched. In this study, the nonlinear properties of two polyfluorene derivatives are investigated. Because of the intense two-photon absorption properties of these polymers primarily a consequence of high conjugation along the polymer backbone, optical limiting behavior and induced fluorescence are observed. In addition to considerable two-photon absorption, the materials also show three-photon absorption that increases their potential use in nonlinear optical applications.

    2. Viscoelastic properties of supramolecular soft materials with transient polymer network (pages 755–764)

      A series of supramolecular soft materials with hydrogen bonded transient networks was prepared by blending carboxy-terminated telechelic poly(ethyl acrylate) (PEA-(COOH)2) and polyethyleneimine (PEI). Rheological measurements revealed the supramolecular network was optimized by stoichiometric balance of amines on PEI and carboxylic acids on PEA-(COOH)2. Since telechelic PEA-(COOH)2 serves as a network strand, the plateau modulus was inversely proportional to MPEA, which was consistent with the correlation length between crosslinks estimated by X-ray scattering measurements.

    3. Negative velocity dependence of friction for poly(2-Acrylamido-2-methyl propanesulfonic acid) hydrogel sliding against a glass surface in the low-velocity region (pages 765–772)

      Poly(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) hydrogel sliding against a glass substrate in water has been found to exhibit complex frictional behavior over a wide velocity region. In the low-velocity region, a “negative” velocity dependence of friction was observed. This wider and weak mixed region, which is in contrast to the extremely narrow mixed region in the case of solid friction, may arise from the decreased shearing area of the PAMPS hydrogel surface with increasing velocity.

    4. Polarization holographic grating recording in the cholesteric azobenzene-containing films with the phototunable helix pitch (pages 773–781)

      Polarization grating recording in cholesteric azobenzene-containing liquid-crystalline films was studied. A range of helix pitches were investigated, showing that diffraction efficiency (DE) decreases as helix pitch increases. Comparison of the induction of polarization gratings in the films with nematic and amorphous polymer systems showed that only the cholesteric films had significant oscillations in the DE signal, as well as a maximum in the first-order DE at the initial stage of the grating recording process.

    5. Superhydrophobic surfaces with low and high adhesion made from mixed (hydrocarbon and fluorocarbon) 3,4-propylenedioxythiophene monomers (pages 782–788)

      Version of Record online: 17 APR 2014 | DOI: 10.1002/polb.23483

      Superhydrophobic surfaces with high and low adhesion are obtained by electropolymerization 3,4-propylenedioxythiophene derivatives containing both a hydrophobic chain and a short fluorocarbon chain. The aim of this work is to replace the use of long fluorocarbon chains, which have bioaccumulative potential in animal and human bodies, while keeping relatively high oleophobic properties.
