▎ 摘　　要

NOVELTY - The composite structure (120) has a carbon nanotube film structure comprising a set of carbon nanotubes that define a pore. A graphene sheet is provided on a surface of the carbon nanotube film structure. The graphene sheet covers the pore, and has a thickness of about 0.335 nm. Two of the set of carbon nanotube films are aligned along different directions. The carbon nanotube films are drawn from a carbon nanotube array, and have high purity. The set of carbon nanotubes is provided parallel to a surface of the carbon nanotube film structure. USE - Graphene sheet-carbon nanotube film composite structure for use in a transmission electron microscope grid (claimed) that is utilized to support a thin specimen to be examined and analyzed. ADVANTAGE - The graphene sheet covers the pore and carries the specimens, so that the specimens are uniformly distributed above the pore, thus achieving a maximum specimen carrying probability. The thickness of the graphene sheet is about 0.335 nm, so that the background noise during the transmission electron microscope observation can be lowered, and the transmission electron microscope photos having higher resolution can be achieved when the size of the specimen is nano in scale. The graphene sheet can be secured between two carbon nanotube film structures, so as to enable the grid to have a stable structure and to be durable. The carbon nanotube films drawn from the carbon nanotube array have high purity, so that the grid does not require elimination of impurities by thermal treatment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a transmission electron microscope grid comprising a graphene sheet-carbon nanotube film composite structure located on a grid part. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic top perspective view of a transmission electron microscope grid.
