NOVELTY - The method involves putting the graphene oxide powder in deionized water. A foaming agent is added in deionized water, is stirred evenly, and is ultrasonically dispersed for 2-4 minutes to obtain a graphene oxide slurry. The acidified carbon nano-tubes are added to the graphene oxide slurry, is stirred evenly, and is ultrasonically dispersed for 2-4 minutes to obtain a mixed slurry. The mixed slurry is put in an oven to dry and remove water. The ethylene glycol and foaming agent are added to the mixed powder. The secondary foaming is performed. The ethylene glycol, foaming agent and mixed powder are fully mixed at a predetermined speed for 30 minutes to obtain a foaming slurry. The prepared foaming slurry is put into a muffle furnace at 200-600 degrees centigrade. The annealing treatment is performed. The foaming slurry is heated for 20-30 minutes and is cooled to normal temperature to obtain a carbon nano-tube composite material. USE - Method for preparing carbon nano-tube composite material (claimed). ADVANTAGE - The carbon nano-tube composite material has good compressive property, uniform mixing, low density, strong anti-pressure ability, and good application prospect.
