  1. Zinc-Catalyzed Hydrosilylation Copolymerization of Aromatic Dialdehydes with Diphenylsilane

    Chuanyang Li, Xiufang Hua, Zehuai Mou, Xinli Liu and Dongmei Cui

    The hydrosilylations of phthalaldehyde, terephthalaldehyde, and isophthalaldehyde with diphenylsilane are catalyzed by heteroscorpionate zinc hydride complex LZnH to afford cyclic compound or linear polymer, respectively. These polymerizations are followed by a new “transfer-propagation” mechanism.

  2. Conjugated Polymers Via Direct Arylation Polymerization in Continuous Flow: Minimizing the Cost and Batch-to-Batch Variations for High-Throughput Energy Conversion

    Continuous flow methods are utilized in conjunction with direct arylation polymerization (DArP) for the scaled synthesis of a semiconducting polymer. The polymer is based on simple thienyl-flanked benzothiadiazole as the acceptor, which is the first β-unprotected substrate to be used in continuous flow via DArP, demonstrating the suitability of this emerging synthetic method for scaled polymer synthesis.

  3. Monomer Protonation-Dependent Surface Polymerization to Achieve One-Step Grafting Cross-Linked Poly(4-Vinylpyridine) Onto Core–Shell Fe3O4@SiO2 Nanoparticles

    Kesong Tian, Ruifei Li, Haiyan Wang, Yan Chen, Wanchun Guo, Yaqi Wang and Zhaopeng Xu

    A monomer protonation-dependent surface polymerization strategy is proposed to achieve one-step grafting of cross-linked poly(4-vinylpyridine) onto core–shell Fe3O4@SiO2 nanostructures. At an approximate pH, partially protonated 4-vinylpyridine sites in aqueous solution can be strongly adsorbed onto deprotonated silanol groups ([BOND]Si[BOND]O) onto Fe3O4@SiO2 nanospheres to ensure direct grafting of cross-linked P4VP macromolecules without any extra surface modification.

  4. Polydopamine Particles Reinforced Poly(vinyl alcohol) Hydrogel with NIR Light Triggered Shape Memory and Self-Healing Capability

    Li Yang, Zhanhua Wang, Guoxia Fei and Hesheng Xia

    Version of Record online: 13 OCT 2017 | DOI: 10.1002/marc.201700421

    The polydopamine particles (PDAPs) composite hydrogels with excellent mechanical properties can be achieved by freezing/thawing treatment, and the formation of physically cross-linked networks from the hydrogen bonding between poly(vinyl alcohol) and PDAPs. Due to the excellent photothermal effect of PDAPs, the composited hydrogels possess rapid shape recovery and efficient self-healing properties under near-infrared light exposure in a short time.

  5. Recent Progress on the Confinement, Assembly, and Relaxation of Inorganic Functional Fillers in Polymer Matrix during Processing

    Processing has a profound influence on the confinement, assembly, and relaxation of functional inorganic fillers in polymer matrix. Therefore, various functionalities can be effectively altered by morphological control during processing. Recently, tremendous development has been reported in this area. A systematic review on this subject is carried out to stimulate greater progress on both fundamental issues as well as applications.
