▎ 摘  要

NOVELTY - Nanowire array modified graphene honeycomb reinforced nano aerogel heat-insulating wave-absorbing composite material comprises graphene honeycomb, nanowire array and nano aerogel. The graphene honeycomb is composed of closely arranged regular hexagonal or regular triangular units, and the unit side length is 0.1-1.0 cm. The density of graphene honeycomb is 0.3-0.5 g/cm3, and the height is 0.1-0.5cm. The surface of graphene honeycomb is enhanced by chemical vapor deposition process to prepare silicon carbide coating. The thickness of silicon carbide coating is 1.0-1.5 mum, which is discontinuous intermittent distribution. The nanowire array is composed of silicon carbide nanowires and hafnium carbide nanowires, which are made by chemical liquid deposition process in the internal pores of the graphene honeycomb. The nanowire array is perpendicular to the surface of the graphene honeycomb, and does not overlap each other 50-80 nm. USE - Used as nanowire array modified graphene honeycomb reinforced nano aerogel heat-insulating wave-absorbing composite material. ADVANTAGE - The nano-wire array modified graphene honeycomb-reinforced nano-gas gel heat-insulating and wave-absorbing composite material has high strength, bearing, heat insulation and wave absorbing property, and provides ceramic-based composite material with light weight and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the method preparing nanowire array modified graphene honeycomb reinforced nano aerogel heat-insulating wave-absorbing composite material.
