▎ 摘  要

NOVELTY - Preparing graphene/carbon nanotube aerogel composite fabric comprises (a) mixing graphene oxide, carbon nanotubes, dispersant and water to obtain graphene oxide/carbon nanotubes dispersion, (b) mixing the graphene oxide/carbon oxide nanotube dispersion with a reducing agent, and performing a reduction reaction to obtain reduced graphene oxide/carbon nanotubes dispersion, (c) cross-linking the reduced graphene oxide/carbon nanotubes dispersion and drying to obtain reduced graphene oxide/carbon nanotube aerogel, and (d) adhering the RGO/CNTs aerogel on the fabric. USE - The composite fabric is useful in the field of electromagnetic shielding (claimed). ADVANTAGE - The method uses reduced graphene oxide and carbon nanotubes to jointly construct aerogels and composite them with fabrics, improves the electromagnetic shielding performance of the fabric and reaches electromagnetic shielding effectiveness of the composite fabric to 34.5 dB. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene/carbon nanotube aerogel composite fabric prepared by the above-mentioned method.
