- Adhesives from Waste Protein Biomass for Oriented Strand Board Composites: Development and Performance
Tizazu H. Mekonnen, Paolo G. Mussone, Phillip Choi and David C. Bressler
Article first published online: 10 MAR 2014 | DOI: 10.1002/mame.201300402
Hydrolyzed proteins recovered from waste proteinaceous materials are chemically modified with diphenylmethane diisocyanate for oriented strand board (OSB) adhesive applications. Fourier transform infrared (FTIR) studies confirmed covalent crosslinking between the diisocyanate and hydrolyzed protein functional groups. Mechanical performance studies of OSB specimens formulated with up to 60% by weight of protein hydrolyzate-based adhesives met commercial application requirements.
- Nanocomposite Membranes for Polymer Electrolyte Fuel Cells
Nagappan Nambi Krishnan, Dirk Henkensmeier, Jong Hyun Jang and Hyoung-Juhn Kim

Nanoparticles have several roles as polymer fillers, among them reducing the bulk material price or adjusting the mechanical properties. In ion conducting polymer membranes, nanoparticles are also used to manipulate the water balance and fuel permeability of the membrane and to increase the ion conductivity. This article shows which membrane properties can be addressed and describes the underlying mechanisms.
- Novel Composites from Eco-Friendly Soy Flour/SBS Triblock Copolymer
Vijay Kumar Thakur, David Grewell, Mahendra Thunga and Michael R. Kessler

The solvent-less synthesis of novel low-cost polymer composites is reported, as procured using environmentally friendly soy flour and SBS triblock copolymer.TheSF/SBS triblock copolymer green composites exhibit a significant improvement in storage modulus over the investigated temperature range and various mechanical/thermal properties.
- Structure-Properties Relationship of In Situ Synthesized Poly(Butylene Succinate)/Silica Nanocomposites: Application in Extrusion Blowing of Films
Nicolas Jacquel, René Saint-Loup, Jean-Pierre Pascault, Alain Rousseau and Françoise Fenouillot
Article first published online: 4 MAR 2014 | DOI: 10.1002/mame.201300370
Addition of nanosilicas during the synthesis via a two-step melt polycondensation reaction of poly(butylene succinate) increases the viscosity of the resulting biobased biodegradable PBS/SiO2 nanocomposites due to polymer–silica interactions. Silica nanoparticles are regularly dispersed in the PBS/SiO2 nanocomposites which exhibit very good processability by film blowing and mechanical properties are greatly enhanced.
- In Situ Doped Polyaniline Nanotubes for Applications in Flexible Conductive Coatings
Sarang P. Gumfekar, Wenjie Wang and Boxin Zhao
Article first published online: 3 MAR 2014 | DOI: 10.1002/mame.201300354
Electrically conductive in situ doped polyaniline nanotubes are fabricated with varied doping levels. The relationships between the level of doping and polyaniline structural features, crystallinity, and conductivity are investigated to elucidate the roles of the dopant in the structure and the properties of the polyaniline nanotubes. The polyaniline nanotubes can be used with polyvinyl alcohol to form an electrically conductive film on flexible substrates.
