▎ 摘 要
NOVELTY - A radar stealth composite film with a sandwich structure comprises core material and skin on both sides of the core material, where skin is graphene, core material comprises a non-woven fabric composed of nanofibers and a conductive polymer, and the nanofibers and the conductive polymer coated on the nanofibers constitute a core-shell structure. USE - Radar stealth composite film with a sandwich structure for use in radar wave, such as aircraft, surface ship and ground armor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing radar stealth composite film with a sandwich structure.
