Design of Self-Healing Supramolecular Rubbers with a Tunable Number of Chemical Cross-Links

Supramolecular rubbers incorporating a large number of physical cross-links through cooperative hydrogen bonds display high self-healing properties but limited solvent and creep resistance due to the lack of chemical cross-links. Increasing both chemical c ...

Process-induced strains in RTM processing of polyurethane/carbon composites

Véronique Michaud, Luis Pablo Canal Casado, Michael Hausmann, Maria Benavente Miana

The development of residual strains and stresses is critical to manufacture composite structures with the required dimensional stability and mechanical performance. This work uses Fiber Bragg Grating (FBG) sensors to monitor strain build-up in carbon fiber ...

Capacitive Strain Sensors Inkjet-printed on PET Fibers for Integration in Industrial Textile

Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero, Giorgio Mattana, El Hadji Malick Camara

We report on printed strain sensors on several meters long PET fibers for integration in textile at large scale. The sensors are made by locally inkjet printing capacitive transducers on cylindrical PET fibers used in industrial textiles. Sensor measuremen ...

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

John Christopher Plummer, Sylvain Cyril Claude Galland, Lars Berglund

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 ...

Fracture Toughness Healing in Epoxy Containing Both Epoxy and Amine Loaded Capsules

Véronique Michaud, Sam Neuser

The feasibility of self-healing epoxy matrices using the same chemistry as the matrix material, namely a standard epoxy-amine system, is demonstrated. The two-component self-healing system is encapsulated in core-shell structures using standard in situ cur ...

Characterization of the Network Structure of PEG Diacrylate Hydrogels Formed in the Presence of N-Vinyl Pyrrolidone

Jeffrey Alan Hubbell, Nicola Tirelli

PEGDA hydrogels copolymerized with NVP using free-radical photopolymerization are used in biomedical applications. These networks consist of a poly(acrylate-co-vinyl pyrrolidone) backbone crosslinked with PEG chains whose crosslink density is dependent on ...

Microscale patterning of hydrogel stiffness through light-triggered uncaging of thiols

Matthias Lütolf, Katarzyna Mosiewicz, Laura Kolb

Mammalian cell behavior is strongly influenced by physical and chemical cues originating from the extracellular matrix (ECM). In vivo, ECM signals are displayed in a spatiotemporally complex fashion, often composed as gradients and in concentration profile ...
