Abstract

The invention discloses a method for implanting a carbon nano tube into substrate materials by utilizing microjet and impact waves, wherein the microjet and the impact waves are produced by laser-inducing cavitation. According to the method, laser is utilized for focusing in dispersion liquid and inducing the dispersion liquid to form cavitation bubbles in the focus position, and the carbon nano tube in the dispersion liquid is pulled to be straight under the action of surface tension with the growing of the cavitation bubbles. When the cavitation bubbles grow to a certain degree and disappear, the high-speed microjet and the impact waves are produced, and the straightened carbon nano tube is fast guided to the surface of the substrate materials. The carbon nano tube is implanted to the substrate materials under the action of instant large momentum, and the carbon nano tube is firmly adhered to the substrate materials depending on machinery meshing of plastic deformation, and combination is firm. The method for implanting the carbon nano tube into the substrate materials is simple in technique and convenient to operate. The carbon nano tube can be firmly adhered to the substrate materials, and the method has strong universality.

Description

technical field [0001] The invention relates to a method in the technical field of nanometer materials, in particular to a method for implanting carbon nanotubes into base materials. Background technique [0002] Carbon nanotubes are a new type of carbon material discovered in 1991. They can be considered as seamless, hollow tubes formed by curling graphene sheets formed by carbon atoms. Walled carbon nanotubes and multi-walled carbon nanotubes. Carbon nanotubes have a very high aspect ratio and a very small radius of curvature at the end, as well as excellent mechanical properties, electrical conductivity, thermal conductivity and chemical stability. Thanks to these unique properties, implanting it into base materials such as soft metal materials (such as gold, silver, copper, etc.) and plastics can greatly improve the performance of the base material, making it possible to prepare various devices with excellent performance. [0003] The existing methods for implanting ca...
