  1. In Situ Synthesis of Polymer Embedded Silver Nanoparticles via Photopolymerization

    Rabia Nazar, Silvia Ronchetti, Ignazio Roppolo, Marco Sangermano and Roberta M. Bongiovanni

    Article first published online: 7 OCT 2014 | DOI: 10.1002/mame.201400204

    A highly versatile UV technology is being opted to cure polymer films embedding metal nanoparticles coated by polypyrrole. Simultaneous reduction of silver ions and photoinduced oxidation of pyrrole to polypyrrole is investigated. In the presence of the UV-curable monomer, multiphasic films are obtained; depending on the silver salt and pyrrole content, a decrease in resistivity is observed.

  2. Fibers Mechanically Similar to Sheep Wool Obtained by Wet Spinning of Gelatin and Optional Plasticizers

    Philipp R. Stoessel, Renzo A. Raso, Tim Kaufmann, Robert N. Grass and Wendelin J. Stark

    Article first published online: 7 OCT 2014 | DOI: 10.1002/mame.201400240

    Gelatin processing into biofibers is achieved by spinning a protein precipitate into ethanol combined with continuous fiber drawing. This allows the production of a continuous porous protein filament, which does not have the limitation of small staple fiber length as, e.g., in wool. Furthermore, the application of plasticizers demonstrates the versatility of the proposed method.

  3. Cationic Aerosol Photopolymerization

    Ertan Akgün, Alex Muntean, Jürgen Hubbuch, Michael Wörner and Marco Sangermano

    Article first published online: 29 SEP 2014 | DOI: 10.1002/mame.201400211

    Photoinitiated polymerization in aerosols is employed for the preparation of spherical polymer particles via cationic polymerization. Crosslinked polymer spheres with a high gel content are obtained by processing vinyl ether and epoxy monomers via aerosol-photopolymerization technique, which exhibits great potential for the development of multifunctional materials.

  4. Altering the Trigger-Behavior of Programmed Shape Memory Natural Rubber (SMNR) by Solvent Vapor

    Dominik Quitmann, Michael Dibolik, Frank Katzenberg and Joerg C. Tiller

    Article first published online: 12 SEP 2014 | DOI: 10.1002/mame.201400224

    The trigger-behavior of a programmed SMNR is significantly changed by treating the constrained sample with solvent vapor. This solvent-induced athermal alteration of the trigger-temperature is a new way to change the properties of a shape memory polymer after programming. The here introduced evaluation method of the trigger-curve by the first derivative allows clearer insights in the trigger-behavior.

  5. Solid-State Properties and Controlled Release of Ranitidine Hydrochloride from Tailored Oxidised Cellulose Beads

    Jani Trygg, Emrah Yildir, Ruzica Kolakovic, Niklas Sandler and Pedro Fardim

    Article first published online: 10 SEP 2014 | DOI: 10.1002/mame.201400175

    Thumbnail image of graphical abstract

    Oxidised cellulose beads were studied as a drug delivery systems at simulated gastrointestinal track. Spectrometric and calorimetric measurements showed that the drug was solidified in amorphous form and the release of the model drug was pH independent, providing biocompatible polymer matrix for fast and controlled drug release.
