▎ 摘　　要

NOVELTY - Preparing wave-absorbing material involves: preparing barium titanate-polyaniline through in-situ polymerization method; uniformly mixing the barium titanate-polyaniline with graphene and polyurethane to obtain a mixture; and transferring the mixture to a mold to prepare barium titanate-polyaniline/graphene/polyurethane foam wave-absorbing material. USE - The method is useful for preparing wave-absorbing material, which is useful in military, aviation and construction. ADVANTAGE - The method enables simple preparation of wave-absorbing material with lightweight, good absorption property and conductivity and excellent synergetic effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the wave-absorbing material prepared by the above method.
