▎ 摘　　要

NOVELTY - Electromagnetic shielding cable, comprises a sheath layer from outside to inside, a shielding layer and a cable core, where the sheath layer is modified graphite aerogel. The cable core is an optical fiber. The modified graphite aerogel is prepared by introducing pyrrolidone microspheres between graphene layers. The pyrrolidone microspheres are prepared by reacting maleic anhydride, N-vinylpyrrolidone and vinylcyclohexyl ether. USE - Electromagnetic shielding optical cable for use in communication, sensing, measurement, control, data acquisition and high technology fields. Uses include but are not limited to mining industry, aerospace industry, military, petroleum and natural gas and high temperature medical applications. ADVANTAGE - The modified graphite gas gel improves the mechanical strength of the sheath layer, further comprising electromagnetic shielding performance, capable of reacting with the melamine foam layer, and capable of reinforcing the strength of cable. The electromagnetic wave can be reflected in the hole in the shielding layer, enhancing the electromagnetic shielding property of the optical cable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of electromagnetic shielding optical cable.
