  1. Synthesis and evaluation of new phosphonic acid-functionalized acrylamides with potential biomedical applications

    H. Betul Bingol, Ayse Altin, Tugba Bal, Sesil Agopcan-Cinar, Seda Kizilel and Duygu Avci

    Article first published online: 27 JUL 2015 | DOI: 10.1002/pola.27746

    Three acrylamides containing phosphonic acid groups were synthesized and evaluated to investigate the relationship between monomer structure and polymerization reactivity/adhesion properties. They were found to be suitable for use as self-etching adhesive monomers because of their etching ability, hydrolytic stability, and copolymerizability with dental monomers. Furthermore, these monomers were used in the fabrication, characterization, and mineralization of hydrogels for tissue engineering applications.

  2. Light-induced controlled free radical polymerization of methacrylates using iron-based photocatalyst in visible light

    An efficient, inexpensive and less toxic iron-based photocatalyst is developed [i.e., Fe(bpy)3(PF6)2] for light-initiated controlled polymerization of methacrylates using α-bromoisobutyrate (EBriB) as an initiator under visible light.

  3. Biomimetic triblock and multiblock copolymers containing l-Phenylalanine moieties showing healing and enhanced mechanical properties

    Article first published online: 27 JUL 2015 | DOI: 10.1002/pola.27753

    Biomimetic triblock and multiblock copolymers of methyl acrylate and N-acryloyl-l-phenylalanine were synthesized via RAFT polymerization mimicking the structure of spider dragline silk. Tensile testing shows that the hydrogen bonding monomer induces a pronounced toughness increase. The new copolymers display a very strong healing effect, with the toughness being increased after drawing, breaking, and healing. Already, a very small content of only 0.1 mol % of N-acryloyl-l-phenylalanine improves the mechanical properties of these polymers significantly.

  4. Reactive copolymer functionalized graphene sheet for enhanced mechanical and thermal properties of epoxy composites

    Qiang Ma, Jing Luo, Yuanxun Chen, Wei Wei, Ren Liu and Xiaoya Liu

    Article first published online: 24 JUL 2015 | DOI: 10.1002/pola.27751

    A novel reactive copolymer VCz–GMA containing carbazole and epoxide group was designed, synthesized and employed to noncovalently functionalize graphene sheet (GNS) for preparing epoxy nanocomposites with enhanced mechanical properties. VCz–GMA facilitates the exfoliation/dispersion level of GNs in epoxy matrix and serves as a linker between GNS and epoxy with improved compatibility and interfacial interaction. The obtained composite showed a remarkable enhancement in both mechanical and thermal property than either the pure epoxy or the GNS/epoxy composites.

    New approach for producing fluorescent gold nanoparticles: Poly(ethylene oxide) homopolymers as reductants in the micelles of amphiphilic fluorosilicone-containing block copolymers

    Jiawen Zhang, Lingmin Yi, Kai Xu, Jing Li and Dongzhi Lai

    Article first published online: 24 JUL 2015 | DOI: 10.1002/pola.27758

    The reduction of gold salts by poly(ethylene oxide) (PEO) homopolymer is very slow and more than 2 days is needed to produce gold nanoparticles (AuNPs). In this work, however, AuNPs are rapidly produced in the micelles of novel amphiphilic poly[methyl(3,3,3-trifluoropropyl)siloxane]-b-poly(acrylic acid) (PMTFPS-b-PAA) block copolymers when using PEO as the reductant. Moreover, fluorescent AuNPs in the block copolymer micelles are presented by a direct monitoring of the micelle shape and the solution optical properties..
