 Graphene Composites

Composites Nanocomposites
Several properties of graphene including mechanical, chemical, and electronic make it useful for fabricating nanocomposite materials. Being 200 times stronger than steel, graphene can dope metals and plastics to increase tensile strength of the composite material. Doping certain polymers with as little as 3% graphene has been reported to induce electrical conductivity in the polymer.

Composites Conductive Inks and Coatings
Graphene, being an inert material, can act as a corrosion barrier when coated onto metal. This works by preventing water and oxygen from contacting the metal surface. Graphene–based ink can be used for making conductive, antistatic, and electromagnetically shielded surfaces.

Composites Gas Barrier Films
Defect free graphene and graphene oxide (GO) create barriers that are impermeable. Dry GO laminates can even prevent helium from passing through it. However,when immersed in water GO acts as a molecular sieve, allowing transport of small ions while blocking large ones. When made with defect like pores, graphene-based films can be used for filtration applications.
