▎ 摘　　要

NOVELTY - A reduced graphene oxide-carbon nanotube/cesium-tungsten bronze composite three-dimensional foam material comprises cesium tungsten bronze nanoparticles supported on a reduced graphene oxide-carbon nanotube foam substrate. USE - Reduced graphene oxide-carbon nanotube/cesium-tungsten bronze composite three-dimensional foam material used in application of light-thermal conversion material. ADVANTAGE - The foam material provides rapid water molecule transport channel by cross-porous network structure and generates multiple scattering effects to reduce transmission loss. The cesium tungsten bronze nanoparticles attached to the foam material absorbs near-infrared light and enhances the light-thermal conversion effect by generating large amount of heat energy which is effectively conducted through the carbon substrate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of reduced graphene oxide-carbon nanotube/cesium-tungsten bronze composite three-dimensional foam material, which involves preparing a reduced graphene oxide-carbon nanotube composite precursor by hydrothermal method, freeze-drying to prepare reduced graphene oxide-carbon nanotube composite three-dimensional foam, dipping the composite foam in cesium tungsten bronze slurry and drying.
