    This work reports the formulation of vinyl ether containing functionalized graphene sheets in order to produce UV-curable conductive inks. Crosslinked nanocomposite materials show a decrease of resistivity of seven order of magnitude with respect to the pristine polymeric matrix.

  2. Bombyx mori Silk Fibers: An Outstanding Family of Materials

    Rui F. P. Pereira, Maria M. Silva and Verónica de Zea Bermudez

    Article first published online: 4 DEC 2014 | DOI: 10.1002/mame.201400276

    Targeting readers from different backgrounds, this review overviews some basic aspects of silk science and focuses less debated aspects of the physical–chemical characterization of Bombyx mori silk fibers. A selection of figures of merit of usual applications and some of the most recent and exciting progress in new technological fields, such as optics, photonics, and electronics, are presented.

  3. The Effect of SDS and TEG on Chain Mobility and Secondary Structure of Decolored Bloodmeal

    Talia M. Hicks, Casparus J. R. Verbeek, Mark C. Lay and James M. Bier

    Article first published online: 18 NOV 2014 | DOI: 10.1002/mame.201400290

    Sodium dodecyl sulfate and triethylene glycol are commonly used to aid thermoplastic processing of proteins. The impact these additives have on protein chain mobility and secondary structure composition during different heating cycles are investigated using synchrotron-based Fourier transform infra-red spectroscopy (FT-IR) and wide angle X-ray scattering (WAXS).

  4. Photocontrol of Mechanical Properties of Pulp Fibers and Fiber-to-Fiber Bonds via Self-Assembled Polysaccharide Derivatives

    Olga Grigoray, Holger Wondraczek, Stephan Daus, Katrin Kühnöl, Seyed Kourosh Latifi, Pooya Saketi, Pedro Fardim, Pasi Kallio and Thomas Heinze

    Article first published online: 17 NOV 2014 | DOI: 10.1002/mame.201400286

    Photoresponsive cellulosic fibers are prepared by charge-directed self-assembly of multifunctional photoactive cellulose derivatives in aqueous environment. The mechanical performance of the single fibers (e.g., stiffness) and the fiber network (e.g., ultimate strength) can be actively controlled via the light induced crosslinking of the pendant coumarin moieties of the adsorbed derivative.

  5. Influence of Boehmite Nanoparticle Loading on the Mechanical, Thermal, and Rheological Properties of Biodegradable Polylactide/Poly(ϵ-caprolactone) Blends

    Stephen C. Agwuncha, Suprakas Sinha Ray, Jarugala Jayaramudu, Caroline Khoathane and Rotimi Sadiku

    Article first published online: 7 NOV 2014 | DOI: 10.1002/mame.201400212

    To broaden the biodegradable PLA possible applications, the blends of PLA/PCL have been processed with boehmite (BAI) nanoparticles. The resulting ternary composites have been characterized for their thermal, mechanical, and rheological properties. Results show that the addition of BAI nanoparticles leads to reasonable improvement in the phase separated morphology of PLA/PCL blends and that a maximum BAI loading of 4 wt% is required for balanced properties.
