      Front Cover: Bead-free and uniform electrospun polystyrene/Ni nanocomposite fibers are found to have higher thermal stability. The nanoparticles still exhibit superparamagnetism, and the magnetic field required to saturate the magnetization is significantly reduced after the nanoparticles are dispersed in the polymer matrix. Further details can be found in the article by X. Chen, S. Wei, C. Gunesoglu, J. Zhu, L. Sun,* A. B. Karki, D. P. Young, and Z. Guo*on page 1775.

    1. Synthesis and Characterization of Highly Luminescent Copolymers of Methyl Methacrylate and Eu-Complexed 5-Acryloxyethoxymethyl-8-hydroxyquinoline (pages 1733–1740)

      Cun-Jin Xu and Bo-Geng Li

      Version of Record online: 22 JUN 2010 | DOI: 10.1002/macp.201000026

      Thumbnail image of graphical abstract

      A highly luminescent Eu-complex monomer featuring thenoyltrifluoroacetone and 5-acryloxyethoxymethyl-8-hydroxyquinoline was first designed and synthesized, which was then further copolymerized with methyl methacrylate to prepare Eu-containing copolymers. The copolymers exhibit typical intense luminescence of the Eu(III) ions even at low Eu content. Furthermore, these polymer luminophors can be cast into clear thin films with good thermal and moisture stable properties.

    2. Photoluminescent Color and Polarized Light Emission Tuning of Fluorene Derivatives Using a Photoreactive H-Bonded Liquid Crystalline Polymer (pages 1741–1749)

      Fluorene (FL) derivatives with pyridine end groups were synthesized to control the photoluminescence (PL) wavelength and polarized light emission using a photoreactive H-bonded polymer (P6CAM), where the λmax of the PL was tuned from 470 to 518 nm. Employing P6CAM as the photoalignment layer realized polarized PL up to PL||/PL = 3.9. Furthermore, photopatterning of the PL color and the direction of the polarized light emission were demonstrated.

      Biodegradable polymer micelles exhibiting extremely high stability were prepared from an amphiphilic block copolymer, polylysine-block-polylactide, by coating with polyanionic hyaluronic acid through polyion complex formation. This PIC-coated polymer micelle can be utilized as an efficient drug delivery vehicle able to survive long-term circulation in the bloodstream.

    2. Spherical Comb Copolymer Micelles and their Application in the Construction of Superhydrophobic Surfaces (pages 1757–1764)

      Zhe Cui, Jianfu Ding, Ludmila Scoles, Qingjun Wang and Qingmin Chen

      Version of Record online: 5 JUL 2010 | DOI: 10.1002/macp.201000218

      Thumbnail image of graphical abstract

      A comb copolymer with a FPAE main chain and narrow-dispersed PMS graft chains is prepared and its micelle formation behavior is studied. Superhydrophobic films with a water contact angle of 165° and a sliding angle of 3° are prepared by double-coating the micelle solution, and they possess a porous composite structure of micrometer-size honeycombs filled with nanofibers and decorated by micelle particles on the surface.

    3. Correlation between Morphology and Mechanical Properties in Zn-Neutralized Sulfonated Polystyrene Ionomer/Poly(ethylene glycol) Blends: Contribution of EFTEM (pages 1765–1774)

      Florent Dalmas, Jean-François Vonet, Solo Randriamahefa and Christine Gaillet

      Version of Record online: 19 JUL 2010 | DOI: 10.1002/macp.201000111

      Energy-filtered transmission electron microscopy (EFTEM) was used in order to investigate the ionic cluster microstructure and the phase morphology in Zn-neutralized sulfonated polystyrene ionomer (SPS-Zn)/poly(ethylene glycol) (PEG) blends. The PEG chains do not hinder the formation of ionic multiplets but they modify the microstructure of the clusters. The absence of ionic plateau observed in DMA is assigned to the decrease of the ionic clusters' stability.

    4. Electrospun Magnetic Fibrillar Polystyrene Nanocomposites Reinforced with Nickel Nanoparticles (pages 1775–1783)

      Xuelong Chen, Suying Wei, Cem Gunesoglu, Jiahua Zhu, Cara S. Southworth, Luyi Sun, Amar B. Karki, David P. Young and Zhanhu Guo

      Version of Record online: 21 JUL 2010 | DOI: 10.1002/macp.201000153

      Bead-free and uniform electrospun polystyrene/Ni nanocomposite fibers are found to have higher thermal stability. The nanoparticles still exhibit superparamagnetic properties and the magnetic field required to saturate the magnetization is significantly reduced after the nanoparticles are dispersed in the polymer matrix.

    5. Indication of Local Phase Separation in Polyimide/Silica Hybrid Polymers (pages 1784–1792)

      Antonino Bartolotta and Pietro Calandra

      Version of Record online: 2 JUL 2010 | DOI: 10.1002/macp.201000110

      Thumbnail image of graphical abstract

      PI/SiO2 hybrid polymers are of considerable interest in modern technology due to their excellent mechanical characteristics. Their sub-micrometer structure has been investigated here by the combined analysis of DMTA, FTIR spectroscopy and specific volumes. The data interpretation provided a better understanding of their working principle and enhanced knowledge for their processing.

    6. Formation of Poly(propylene)-Based Biocomposite Films and Their Use in the Attachment of Methylene Blue (pages 1793–1802)

      Jesica A. Cavallo, Cesar G. Gomez and Miriam C. Strumia

      Version of Record online: 2 JUL 2010 | DOI: 10.1002/macp.201000047

      Biomedical materials obtained from the combination of natural and synthetic polymers are being broadly used. Taking advantage of its good mechanical properties, poly(propylene) is modified by acrylic acid photograft polymerization. After immobilizing methylene blue on poly(acrylic acid) by electrostatic bonds, a chitosan layer is attached which provides biocompatibility properties to the film surface.

    7. Preparation and Properties of Novel Triphenylpyridine-Containing Hyperbranched Polyimides Derived from 2,4,6-Tris(4-aminophenyl)pyridine under Microwave Irradiation (pages 1803–1813)

      W. Chen, W. Yan, S. Wu, Z. Xu, K. W. K. Yeung and C. Yi

      Version of Record online: 5 JUL 2010 | DOI: 10.1002/macp.201000193

      Novel amino- and anhydride-terminated triphenylpyridine-containing hyperbranched polyimides are prepared successfully for the first time deriving from BB′2-type aromatic triamine, TAPP, via a conventional two-step process under microwave irradiation. The resulting novel hyperbranched polyimides are investigated and proved to be promising organosoluble, high temperature resistant materials for organic photoluminescent, and photoelectric applications.

      Xing Wang, Taolei Sun, Chunyu Wang, Ce Wang, Wanjin Zhang and Yen Wei

      Version of Record online: 2 JUL 2010 | DOI: 10.1002/macp.201000194

      For the first time, the triplet peaks with an integral area ratio of 1:1:1 and a coupling constant 1JNH = 51.1 Hz in the 1H NMR spectra of doped PANI are assigned. It is demonstrated that they can be used to determine the effective doping and conducting properties of the polymer.

      A new carbazole-containing HPU, used as hole-transporting material, was conveniently prepared by one-pot Ullmann C–N coupling reaction through a “AB2 + A2 + B2” approach. A two-layer OLED device, using HPU as hole-transporting layer and Alq3 as the light-emitting layer, was fabricated, which demonstrated very good stability during passage of current. The luminance efficiency reached 1.14 cd · A−1 at the maximum current density of 1 240 mA · cm−2, while the maximum luminance efficiency was 1.65 cd · A−1, indicating the high morphological and thermal stability of HPU.

    10. Photocurable Shape-Memory Copolymers of ε-Caprolactone and L-Lactide (pages 1826–1835)

      Minoru Nagata and Yu Yamamoto

      Version of Record online: 2 JUL 2010 | DOI: 10.1002/macp.201000106

      Thumbnail image of graphical abstract

      Novel biodegradable and photocurable copolymers were synthesized by polycondensation of a mixture of poly(L-lactide) diol (equation image = 10 000) and poly(ε-caprolactone) diol (equation image = 10 000) with a photosensitive chain extender. The photocured copolymers with higher PCL contents exhibited excellent shape-memory properties at a recovery temperature of 45–60 °C for different tensile strains of 100–1 000%. The mechanism driving the thermal shape-memory effect has been demonstrated.
