All-polyamide nanofibrillar composites by in situ fibrillation of aramid fibers

John Christopher Plummer, Holger Frauenrath, Sylvain Cyril Claude Galland, Pascal Alexander Schouwink, Nicolas Candau, Oguzhan Oguz

All-polyamide composites containing up to 30 vol% highly dispersed PPTA nanofibrils with diameters in the range 50-500 nm were prepared by melt-compounding polyamide 6,10 (PA610) with chopped poly(p-phenylene terephthalamide) (PPTA) fibers in the temperatu ...

High-performance polyamides with engineered disorder

John Christopher Plummer, Véronique Michaud, Julien Philippe Cretenoud, Holger Frauenrath, Sylvain Cyril Claude Galland, Nicolas Candau

The extraordinary property profiles of many biological materials derive from their hierarchical structure and control of order and disorder at different length scales. Application of these concepts to the design of synthetic polymers may provide new routes ...

High-temperature copolyamides obtained by the efficient transamidation of crystalline-crystalline polyamide blends

John Christopher Plummer, Véronique Michaud, Holger Frauenrath, Sylvain Cyril Claude Galland

High-performance thermoplastic composites based on semiaromatic polyamides are prime candidates for metal replacement in lightweight structural applications. However, the low ductility and toughness of semiaromatic polyamides remain major obstacles to thei ...

Influence of processing routes on morphology and low strain stiffness of polymer/nanofibrillated cellulose composites

Pierre-Etienne Bourban, Yves Leterrier, John Christopher Plummer, Lars Berglund, Sylvain Cyril Claude Galland

The morphology of polymer/nanofibrillated cellulose (NFC) composite sheets produced using different techniques and its influence on low strain stiffness were assessed by optical and transmission electron microscopy. Solvent processing led to relatively hom ...

Cellulose nanofiber network for moisture stable, strong and ductile biocomposites and increased epoxy curing rate

John Christopher Plummer, Lars Berglund, Sylvain Cyril Claude Galland

Nanocomposites with high volume fractions (15-50 vol%) of nanofibrillated cellulose (NFC) were prepared by impregnation of a wet porous NFC network with acetone/epoxy/amine solution. Infrared spectroscopy studies revealed a significant increase in curing r ...
