▎ 摘　　要

NOVELTY - Preparation of layered microwave absorbing material comprises laser carbonizing polymer film to form carbides to obtain base layer, coating mixture solution of metal salts on base layer, laser processing mixed solution of metal salt to form loss layer, coating high molecular polymer solution on loss layer, laser processing polymer solution to form polymer carbonization layer, repeating steps to form superimposed layer of alternating stacking of loss layer and polymer carbonization layer on base layer and annealing material. The layered absorbing material comprises base layer, loss layer formed on base layer and polymer carbonized layer formed on loss layer. USE - The method is used for preparation of layered microwave absorbing material. ADVANTAGE - The absorbing material has simple preparation, thin thickness, rapid mass production, adjustable absorbing performance and good absorbing effect.
