▎ 摘　　要

NOVELTY - Electromagnetic shielding composite material comprises absorption layer and reflective layer compounded on absorption layer; the absorption layer includes modified resin layer; the reflective layer includes metal nanowire film layer. USE - The shielding composite material is useful in field of 5G communication or aerospace (claimed). ADVANTAGE - The shielding composite material: has high electromagnetic shielding efficiency, low electromagnetic wave reflection and excellent mechanical properties; and can replaces the traditional electromagnetic shielding composite material to be applied to 5G communication field, and aerospace field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the electromagnetic shielding composite material comprising (1) mixing filler A and solvent, adding filler B, continuously mixing, adding ferric chloride, alkali and hydrazine hydrate and remixing, and reacting to obtain a modified filler; (2) extruding and granulating the modified filler obtained in the above steps and resin, obtaining modified resin; (3) hot pressing the modified resin, obtaining modified resin layer; and (4) carrying plasma treatment, and compounding metal nanowire dispersion on the modified resin layer to obtain an electromagnetic shielding composite material.
