NOVELTY - Preparing polymer foam-based carbon nano-composite material, involves dispersing graphene oxide in deionized water and ultrasonically dispersing to obtain negatively charged graphene aqueous dispersion. The gamma -aminopropyl triethoxysilane is refluxed in a nitrogen atmosphere protected toluene solvent at 60-100 degrees C for 12-24hours on hydroxylated carbon nanotubes surface aminosilane modification. The solution is subjected to centrifugal washing and then freeze-dried. The resulting aminosilane modified carbon nanotube is dispersed in deionized water. USE - Method for preparing polymer foam-based carbon nano-composite material (claimed). ADVANTAGE - The method enables to prepare polymer foam-based carbon nano-composite material that has good flexibility, resilience and sensitive response. DETAILED DESCRIPTION - Preparing polymer foam-based carbon nano-composite material, involves dispersing graphene oxide in deionized water and ultrasonically dispersing to obtain negatively charged graphene aqueous dispersion. The gamma -aminopropyl triethoxysilane is refluxed in a nitrogen atmosphere protected toluene solvent at 60-100 degrees C for 12-24hours on hydroxylated carbon nanotubes surface aminosilane modification. The solution is subjected to centrifugal washing and then freeze-dried. The resulting aminosilane modified carbon nanotube is dispersed in deionized water. The hydrochloric acid solution is added dropwise to adjust the pH to 5-6, to obtain a positively charged aqueous solution of aminosilane modified carbon nanotubes. The polymer open cell foam is immersed in the aqueous graphene dispersion is extruded, saturated and dried in an oven at 60-90 degrees C to obtain a polymer foam-based graphene composite material. The polymer foam-based graphene composite material is then immersed amino silane modified carbon nanotube aqueous dispersion and repeatedly squeezed, saturated and dried at 60-90 degrees C, and repeated for 1-6 times to obtain the polymer foam based carbon nano-composite material by electrostatic adsorption and layer assembly of different layers of polymer foam-based matrix-carbon nano composites is obtained. The obtained material is placed in a hydrothermal kettle. The hydrazine hydrazine solution is added to the oven at 85-100 degrees C for 1-2hours, and the composite material is collected and completely dried in an oven at 60-90 degrees C to obtain the product.
