USE - Used as bidirectional wave absorbing transparent electromagnetic shielding device based on graphene net grid and transparent conductive film. ADVANTAGE - The device: has strong shielding and low reflection characteristics, high visible light transmittance through the multilayer structure and electromagnetic shielding window to solve the problem of existing bidirectional low electromagnetic reflection, high electromagnetic shielding and high transmission cannot be balanced. DETAILED DESCRIPTION - Bidirectional wave absorbing transparent electromagnetic shielding device based on graphene net grid and transparent conductive film comprises orderly overlapped and parallel configuration a transparent absorption layer A (3), a transparent medium A (4), a transparent reflective layer (5), a transparent medium B (6) and a transparent absorbing layer B (7). The transparent absorption layers A, B (3, 7) are composed of a graphene grid film in which the N layer is separated by a transparent medium. The transparent reflective layer is composed of a transparent conductive film including a transparent metal compound thin film, a silver nanowire film or a metal grid. The graphene grid film constitutes the transparent absorbing layers A and B composed of a graphene film having a mesh array structure. The meshed array structure is a two-dimensional array structure in which the cell units are periodically set. The mesh unit has a square hole or a circular hole shape. The cell size is in the order of submicron to millimeter. The cell array is in the order of microns to millimeters. The cell area ratio of the cell unit is 0.05 and 0.7. The mesh cell aperture area ratio is an array cycle. The ratio of the cell area of the cell unit to the area of the cell cycle unit. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the bidirectional wave absorbing transparent electromagnetic shielding device based on graphene net grid and transparent conductive film.
