▎ 摘　　要

NOVELTY - Broadband cable with good shielding effect comprises a conductor layer, an insulating layer and a shielding layer, which are sequentially from inside to outside. The preparation raw material of the shielding layer includes a piece of graphene USE - Broadband cable with good shielding effect useful in the field of electric wire cable for transmitting electromagnetic energy, information and realizing electromagnetic energy conversion. ADVANTAGE - The cable: has better shielding effect and adhesion reaches 5B; can be long-acting shielding electromagnetic wave; can provide a reliable basis for the light weight development of the cable by using a thin shielding layer; modifies the three-dimensional porous graphene so that the silver mirror reaction is attached with a layer of thin silver layer on the three dimensional (3D) porous surface graphene reflecting most of the electromagnetic wave effect; can continuously reflect the electromagnetic wave entering the shielding layer, so as to enhance the shielding layers to dissipate or absorb the electromagnetic waves to improve the shielding effect of shielding layer to electromagnetic waves. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a processing technique of the broadband cable with good shielding effect.
