Overview | Product Information | Related Products
Graphene carbon nanotubes composite (CAS number 308068-56-6), also referred to as graphene carbon nanotubes hybrid, composes of covalently bonded graphene (2D) nanopowders and multiwalled carbon nanotubes (1D).
Carbon nanotubes (CNTs) have improved electrical conductivity and a large surface area, while graphene or chemically modified graphene nanosheets possesses high charge density and outstanding mechanical properties. Graphene is also known to form irreversible agglomerates or to restack to form graphite through the van der Waals interactions during the drying process. CNTs can be used as spacers for graphene nanosheets to prevent agglomeration happening between the layers.
Graphene carbon nanotubes show effective improvements in electrical and mechanical properties with enhanced electrical conductivity, additional flexibility, high mechanical stability, and readily accessible surface area. The combination of these two materials creates a versatile 3D graphene-CNT hybrid network with synergic properties.
