▎ 摘　　要

NOVELTY - Preparing wood composite material comprises (i) taking the pre-processed with round hole of the circular single plate, (ii) preparing activating liquid A, activating liquid B, activating liquid C, chemical plating copper liquid, chemical plating nickel liquid, hollow fiber and ferric oxide graphene oxide, (iii) placing the round veneer in the activating solution A to activate and placing in the activating solution B to activate, (iv) placing the round veneer processed in the chemical plating copper solution, adding hollow fiber, performing chemical plating copper operation, (v) placing the circular single plate in the activating liquid C and placing in the activating liquid B, (vi) placing the round single plate processed in chemical plating nickel liquid, adding ferric oxide graphene oxide, performing chemical plating nickel operation and drying. USE - The method is useful for preparing wood composite material. ADVANTAGE - The method: has high absorption and low reflection synergistic effect in wide frequency range as core.
