    A visible light-responsive multilayer system, with an azo-containing polymer film as the intermediate layer has been developed for the controlled fabrication of the hierarchically patterned surfaces. It is based on the combined strategy of surface wrinkling with visible light irradiation. This study offers a new avenue to create micro/nano patterned surfaces on diverse functional films based on the stimuli-responsive wrinkling-based adaptive system.

  2. Sequestration of Methylene Blue into Polyelectrolyte Complex Coacervates

    Polyelectrolyte complex coacervate formation results in a dense liquid phase with a range of properties including the ability to sequester small molecules into the coacervate. This study shows that π–π interactions play a more significant role in the sequestration of aromatic dyes into the polyelectrolyte complex coacervate phase than electrostatic interactions.

  3. Polymer-Fullerene Network Formation via Light-Induced Crosslinking

    Yuuki Sugawara, Kai Hiltebrandt, Eva Blasco and Christopher Barner-Kowollik

    Here, a novel avenue for polymer-fullerene network formation is demonstrated by employing light-induced chemistry based on tetrazole cycloaddition. The networks can be readily fabricated by simple UV irradiation of a tetrazole-functionalized polymer in the presence of fullerenes.

  4. Sustainable Electrochemically-Mediated Atom Transfer Radical Polymerization with Inexpensive Non-Platinum Electrodes

    Marco Fantin, Francesca Lorandi, Abdirisak A. Isse and Armando Gennaro

    Version of Record online: 22 JUN 2016 | DOI: 10.1002/marc.201600237

    Well-controlled electrochemically-mediated atom transfer radical polymerization can be accomplished in aqueous media on cheap, nonnoble metal electrodes such as stainless steel and NiCr alloys. A highly simplified setup based on a two-electrode, undivided cell with a sacrificial Al anode works very well, demonstrating that extremely expensive Pt electrodes are not needed.

  5. On the Termination Mechanism in the Radical Polymerization of Acrylates

    Nicholas Ballard, Shaghayegh Hamzehlou, Fernando Ruipérez and José M. Asua

    Version of Record online: 21 JUN 2016 | DOI: 10.1002/marc.201600278

    Intramolecular transfer to polymer complicates the determination of the mode of termination in radical polymerization of acrylates. Comparison of experimental results and simulations show that bimolecular termination of end chain radicals likely proceeds by combination, while midchain radicals have a stronger tendency to undergo disproportionation.
