Abstract

The invention relates to a preparation method of a polymeric based carbon nano tube composite material in the technical field of nano materials. The steps of the preparation method: firstly, according to the proportion that the mass percent content of a carbon nano tube in the composite material ranges from 0.01 to 10%, the carbon nano tube is directly added or pre-scattered into a liquid medium,a monomer and an oligomer of the polymeric base material or monomer solution or oligomer solution are added, then the mixture is obtained by mixing; secondly, the radiating treatment is carried out on the mixture by an electron beam and the polymer composite material containing carbon nano tube is obtained. The preparation method includes: unsaturated carbon atoms are directly produced on the surface of the carbon nano tube by the radiation of the electro beam and are completely reacted in the base polyreaction at once to prepare the composite material, thus increasing the interface intensitybetween the carbon nano tube and the base, improving the modifying efficiency of the carbon nano tube and keeping the technical advantages of the solidification of the electro beam, such as environmental protection, high efficiency, low consumption, strong flexibility, high reliability, etc.

Description

Preparation method of polymer-based carbon nanotube composite material technical field The invention relates to a preparation method in the technical field of nanomaterials, in particular to a preparation method of a polymer-based carbon nanotube composite material. Background technique Carbon nanotubes are currently the most concerned nanomaterials and are considered to have the most specific properties. The density of carbon nanotubes is only about 1 / 10 of that of steel, but the theoretical and measured Young's modulus are about 5TPa and 1.8TPa respectively, almost the same as the modulus of diamond, which is the highest known material modulus, and its tensile strength It is 200GPa, close to the upper limit of the strength of natural materials, 100 times that of steel and 20 times that of carbon fiber; its elastic strain can reach up to 12%, about 60 times that of steel. It not only has the inherent properties of carbon fiber, but also has the electrical and thermal con...
