▎ 摘　　要

NOVELTY - Preparing sulfur-doped highly conductive graphene type light absorbing material involves reacting graphene and a thioacetamide hydrothermally in a mixed solution of hydrogen peroxide and distilled water obtaining graphene doped with lightabsorbing material element. The raw material graphene is hydrothermally modified to obtain sulfur element. USE - Method for preparing sulfur-doped highly conductive graphene type light absorbing material used as a broadband absorber and for treating civil electromagnetic interference and radar stealth. ADVANTAGE - The method enables to prepare sulfur-doped highly conductive graphene type light absorbing material in a simple manner with good impedance matching and electromagneticattenuation ability.
