3D - Un aérogel en mousse de graphène

L'aérogel c'est une matière super légère et solide découverte en 1931 (99,8 % d’air et présente une densité de 3 mg/cm3) mais qui supporte environ 2000 fois son poids.
Arriver à en fabriquer par du graphène pourra ouvrir de nouvelles perspectives côté rigidité, conductivité, ...

A new type of graphene aerogel will make for better energy storage, sensors, nanoelectronics, catalysis and separations.

Lawrence Livermore National Laboratory researchers have made graphene aerogel microlattices with an engineered architecture via a 3D printing technique known as direct ink writing. The research appears in the April 22 edition of the journal, Nature Communications.

The 3D printed graphene aerogels have high surface area, excellent electrical conductivity, are lightweight, have mechanical stiffness and exhibit supercompressibility (up to 90 percent compressive strain). In addition, the 3D printed graphene aerogel microlattices show an order of magnitude improvement over bulk graphene materials and much better mass transport.
