▎ 摘　　要

NOVELTY - A shielding radio frequency coaxial cable comprises an inner conductor, an insulating layer, shielding layer comprising graphene/polyamide composite shielding layer, and an outer sheath. The graphene/polyamide composite material is prepared by adding graphene oxide to molten polymer monomer, adding initiator and activator, thermally polymerizing, cooling, pelletizing, heating the obtained resin pellets, adding filler comprising graphene oxide, mixing, cooling, and granulating. USE - Shielding radio frequency coaxial cable. ADVANTAGE - The shielding radio frequency coaxial cable contains shielding layer which can be directly heated and extruded. The method enables simplified production of the shielding radio frequency coaxial cable with improved production efficiency. The insulating layer, shielding layer and outer sheath layer are directly co-extruded. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the shielding radio frequency coaxial cable.
