▎ 摘　　要

NOVELTY - The device has a cutting module (1) arranged on a bottom part of a graphene paper (4). A fixing module (2) is arranged in an upper part of the cutting module. A coiling module (3) is formed in a coating film (31) on the graphene paper. The cutting module is provided with an integrated cutter (11). The cutting module is connected with an upper part of a supporting base (17). A filter screen (12) is connected with a lower part of the integrated cutter. A valve (13) and a vacuum pump (14) are located on a lower part of the supporting base. A sealing gasket (15) and a sealing screw (16) are respectively arranged on two sides of the supporting base. USE - Graphene paper film preparing device. ADVANTAGE - The device can ensure quality and precision of graphene paper cutting, and a prepared graphene paper film has a large-area monolith structure, and promotes bonding of the graphene paper film and composite material so as to ensure stability, thus avoiding delamination, and hence effectively improving electrical and thermal conductivity of a composite surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene paper film preparing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene paper film preparing device.
