Abstract

The invention provides a preparation method for a plastic / nano carbon composite material. The method comprises the following steps: preparing thermoplastic plastic into a thin film; uniformly coating the surface of the plastic thin film with nano carbon slurry and drying; and carrying out three-dimensional hot pressing and compounding to form the composite material capable of being machined and molded. By virtue of the method, the dispersion effect of a nano carbon material in plastic can be effectively improved, so that the conductive, heat conducting and mechanical properties of the plastic composite material are effectively improved.

Description

technical field [0001] The invention relates to the field of material synthesis, in particular to the technical field of inorganic non-metallic composite materials, in particular to a method for preparing plastic / nano-carbon composite materials. Background technique [0002] Thermoplastics are important materials for national defense and national economic applications. The excellent properties of nano-carbon materials in terms of electrical conductivity, thermal conductivity and mechanical mechanics make them ideal reinforcements for polymer materials. Adding them to the plastic matrix to form composite materials can greatly improve the electrical conductivity, thermal conductivity and mechanical properties of plastics. [0003] However, the surface energy of carbon nanomaterials is high, such as carbon nanotubes are particularly prone to agglomeration, and it is difficult to achieve uniform dispersion in the polymer matrix. At present, chemical treatment methods will damag...
