For applications in biosensors, drug delivery, hydrogen storage and supercapacitors, transistors, solar cells, water purification, aerospace and automobiles
Graphene carbon nanotubes composite, also referred to as graphene carbon nanotubes hybrid, composes of a covalently bonded graphene (2D) nanopowders and multiwalled carbon nanotubes (1D).
Carbon nanotubes (CNTs) have improved electrical conductivity and high readily accessible surface area while graphene or chemically modified graphene nanosheets possesses high charge density and outstanding mechanical properties. However, 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 thus can 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 2D graphene of high charge density and 1D CNTs of large surface area generates a versatile 3D graphene-CNT hybrid network with synergic properties.
With improved electrical conductivity and high readily accessible surface area, graphene carbon nanotubes composite may find applications in the followings.
