Problems solved by technology

However, carbon nanotubes have very large specific surface area, high aspect ratio and strong van der Waals attraction between carbon nanotubes, so that carbon nanotubes are extremely prone to agglomeration and entanglement.
If the dispersion problem in polymer resin cannot be solved well, it will greatly affect the modification effect of carbon nanotubes on resin

Abstract

The invention discloses a preparation method of a carbon nano-tube / amorphous carbon / epoxy resin composite material, belonging to the field of synthesis and application of carbon nano composite materials. The method comprises the steps of firstly, preparing carbon nano-tube sponge; secondly, preparing a carbon nano-tube / amorphous carbon composite material; finally, preparing the carbon nano-tube / amorphous carbon / epoxy resin composite material. A carbon nano-tube / amorphous carbon aerogel is prepared by using a chemical vapor deposition method, and epoxy resin is directly poured into pores of the carbon nano-tube / amorphous carbon aerogel by using the porosity of the carbon nano-tube / amorphous carbon aerogel, thus achieving the effect of enhancing the epoxy resin and directly obtaining the carbon nano-tube / amorphous carbon / epoxy resin composite material with a uniform structure at the same time. The strength and modulus of the prepared carbon nano-tube / amorphous carbon / epoxy resin composite material disclosed by the invention are improved greatly as compared with those of pure epoxy resin and carbon nano-tube / epoxy resin.
