Electrophoresis device applicable to oriented deposition of carbon nanotubes on carbon fiber and using method thereof

Abstract

The invention discloses an electrophoresis device applicable to oriented deposition of carbon nanotubes on carbon fiber and a using method thereof, relates to the electrophoresis device and the usingmethod thereof, and solves the problems as follows: in a preparation method of a CNT / CF cross-scale reinforcing body, vertical arrangement of the CNTs on the surface of the CF along the radial direction of the carbon fiber only can be achieved only by a CVD method, but the CVD method is relatively cumbersome in operation, pollution is caused because the surface of the carbon fiber is required to be impregnated and coated with a catalyst, and in addition, during deposition of the CNTs by the CVD method at high temperature, under a high-temperature catalyst condition, significant decrease in thetensile strength of the carbon fiber is caused and continuous operation cannot be achieved. The electrophoresis device comprises an electrode supporting and fixing device, a carbon fiber pulling andguiding device and a liquid accommodating device. The using method comprises the following steps: 1, fixing the carbon fiber; 2, fixing the electrode supporting and fixing device; 3, pulling and fixing the carbon fiber; 4, preparing a carbon nanotube isopropanol dispersion containing magnesium ions; 5, orientedly depositing the carbon nanotubes on the surface of the carbon fiber.

Description

technical field [0001] The invention relates to an electrophoretic device and a method for using the same. Background technique [0002] Compared with traditional metal materials, carbon fiber composite materials have higher strength and modulus and lighter weight, so they are widely used in aerospace, transportation, wind power generation and sports equipment and other fields. As an anisotropic material, the radial properties of traditional carbon fiber composites are much lower than the axial properties. Nanoscale carbon nanotubes (CNTs) are introduced into carbon fiber-reinforced resin-based composites to improve the radial properties of fiber composites due to their excellent mechanical, thermal, and electrical properties. [0003] To introduce carbon nanotubes into the surface of carbon fibers to construct CNT / CF cross-scale reinforcements, commonly used methods include vapor deposition method CVD, chemical grafting method, sizing agent impregnation method, electrophor...

AI Technical Summary

Problems solved by technology

However, the CVD method is more cumbersome to operate, and it is necessary to impregnate and coat the catalyst on the surface of the carbon fiber, causing pollution

Depositing CNTs at a high temperature of 600 ° C to 800 ° C, the tensile strength of carbon fibers will be significantly reduced by 30% to 40% under high temperature catalyst conditions

In addition, the reactors of the CVD method are mostly tubular furnaces that operate intermittently, which cannot realize continuous operation, which limits the practical application and promotion.
