  1. 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

    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).

  2. 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

    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.

  3. 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.

  4. Hierarchical Self-Assembly in Monoaxially Electrospun P3HT/PCBM Nanofibers

    Caitlin Dillard, Richa Singhal and Vibha Kalra

    Article first published online: 7 NOV 2014 | DOI: 10.1002/mame.201400214

    P3HT/PCBM nanofibers are fabricated by monoaxial electrospinning and are shown to exhibit promising morphologies for organic solar cells compared to solution-cast films. X-ray scattering in the small angle shows nanofibers have smaller domain spacing; wide angle shows improved crystallinity. Interdigitated pathways 20–30 nm aligned along the fiber axis are observed with transmission electron micrographs of microtomed fiber sections.

  5. Preparation of Epoxy/Jeffamine Networks Modified With Phosphonium Based Ionic Liquids

    Bluma G. Soares, Adriana A. Silva, Jéssica Pereira and Sébastien Livi

    Article first published online: 5 NOV 2014 | DOI: 10.1002/mame.201400293

    Alkylphosphonium–-based ionic liquids were employed as new additives for the design of epoxy networks, aiming to develop systems with good thermal stability and conductivity. The presence of such ionic liquids imparts better ionic conductivity to the epoxy system without affecting the mechanical performance.
