The invention provides an electromagnetic shielding composite material, which includes an absorption layer and a reflection layer compounded on the absorption layer; the absorption layer includes a modified resin layer; and the reflection layer includes a metal nanowire film layer. The present invention adopts specific layer materials, combined with the laminated structure of the absorbing layer-reflecting layer, to obtain the electromagnetic shielding composite material with specific structure and composition. The multi-layer electromagnetic shielding composite material prepared by using the laminated structure of the absorption layer-reflection layer in the present invention can have many advantages such as high electromagnetic shielding efficiency, low electromagnetic wave reflection and excellent mechanical properties, and can replace the traditional electromagnetic shielding composite material.
