Fabrication process of silicone-based dielectric elastomer actuators

Herbert Shea, Samuel Rosset, Oluwaseun Adelowo Araromi, Samuel Schlatter

This contribution demonstrates the fabrication process of dielectric elastomer transducers (DETs). DETs are stretchable capacitors consisting of an elastomeric dielectric membrane sandwiched between two compliant electrodes. The large actuation strains of ...

Effect of carbon surface functional groups on the synthesis of Ru/C catalysts for supercritical water gasification

Christian Ludwig, Frédéric Vogel, Gaël Peng

A carbon support was treated with HNO3 to create surface functional groups (e.g. -COOH, -OH), which were then characterized by TGA, TPD, CNS elemental analysis, and Boehm titration. HNO3 modified the carbon surface properties by adding a high amount of car ...

Ultrafast All-Polymer Electrically Tunable Silicone Lenses

Herbert Shea, Samuel Rosset, Luc Maffli

Dielectric elastomer actuators (DEA) are smart lightweight flexible materials integrating actuation, sensing, and structural functions. The field of DEAs has been progressing rapidly, with actuation strains of over 300% reported, and many application conce ...

From Reinforcement to High-Performance Damping : An Oligopeptide Toolbox for Tailored Elastomers

Emmanuel Croisier

Biomaterials such as structure proteins are constructed from limited sets of chemical building blocks and supramolecular motifs. Nevertheless, they exhibit extraordinary properties specifically tailored for a broad range of applications because hierarchica ...

Epoxy-graphite Resistive Composites : Formulation, Characterization and Applications

Nathalie Sophie Adeline Serra

In this thesis, we proposed to study polymer-based thick-film resistors (TFRs) made of graphite particles dispersed in an epoxy matrix. Three main axes were investigated: formulation of the composites, characterization with the determination of electrical, ...
