Abstract

The invention discloses a super-hydrophobic and anti-icing carbon fiber board and a preparation method thereof. A ZnO-CFB (carbon fiber board) comprises an array zinc oxide upper layer arranged on the upper surface of the carbon fiber board and an array zinc oxide lower layer arranged on the lower surface of the carbon fiber board. The preparation method comprises the following steps: firstly soaking the carbon fiber board in a crystal seed solution, taking out, drying and solidifying crystal seeds; and then soaking in a growth solution to perform low-temperature crystal growth, thereby obtaining the array zinc oxide layers with the thickness of 2-3 microns on the upper and lower surfaces of the carbon fiber board. Water droplets have the contact angle of 152 degrees and the rolling angle of 3 degrees on the ZnO-CFB disclosed by the invention. The ZnO-CFB disclosed by the invention can still keep a super-hydrophobic state at the temperature of -15 DEG C and the service life of the ZnO-CFB can be prolonged.

Description

Technical field [0001] The invention belongs to the field of interface chemistry. By preparing a regular ZnO nano-array on the surface of the carbon fiber board, the carbon fiber board has the effects of super hydrophobic and anti-icing. Background technique [0002] Carbon Fiber Board (CFB) materials are widely used in automobiles, large equipment and other fields because of their light weight and high strength. Because the carbon fiber board material is drawn by impregnating carbon fiber in a resin material. Therefore, there is a layer of resin material on its surface. If the carbon fiber board is used for a long time in a high humidity and cold environment, it is likely to cause the failure of the carbon fiber board material and affect the service life of the carbon fiber board. Summary of the invention [0003] In order to improve the weather resistance of the carbon fiber board material, the present invention modifies the surface of the carbon fiber board material to achiev...
