Abstract
The invention belongs to the technical field of conductive composite materials, and particularly relates to a carbon nanotube plastic conductive composite material and a wet preparation process thereof. The carbon nanotube plastic conductive composite material comprises a carbon nanotube, an acrylic emulsion, an acrylic resinemulsion, a polystyreneemulsion, a conductive filler, lauryl sodiumsulfate, polyvinylpyrroline and polypropionyl nitrogen hybridized propane. P electrons of carbon atoms on the carbon nanotube form large-range delocalized pi bonds, the conjugation effect is remarkable, and the carbon nanotubes have special electrical properties, so that the carbon nanotubes have good conductivity, and meanwhile, the lauryl sodiumsulfate and the carbon nanotubes react to form pi-pi conjugation, so that the mechanical properties of the carbon nanotube plastic conductive composite material can be enhanced. A wet preparation process is adopted to make the materials contact more fully and the compound dispersed more uniformly, and meanwhile, the wet preparation process can avoid high temperature, so that a large amount of energy is saved, and the characteristics of a high polymer material are prevented from being damaged by the high temperature.
Description
Technical field[0001]The present invention relates to the technical field of conductive composites, and in particular, a carbon nanotube plastic conductive composite material and a wet preparation process thereof.Background technique[0002]Carbon nanotubes, but also known as the Pakistani, is a one-dimensional quantum material having a special structure (radial dimension is nanometric, axial dimension is substantially sealing) both ends of the tube. Carbon nanotubes are mainly composed of a carbon atom in a hexagonal to dozens of coaxial tubes, and the layer is maintained between the layers and the layers, about 0.34 nm, the diameter is generally 2 to 20 nm, and according to carbon The six-sided different orientation can be divided into three kinds of saw tooth shapes, armchair and spiral types, wherein the spiral carbon nanotubes have chiral, and the saw tooth shape and armchair type carbon nanotubes are not chiral. Carbon nanotubes are perfect as one-dimensional nanotoma, light wei...
