Preparation method and application of reusable coating carrier

The invention belongs to the technical field of vacuum coating, and particularly discloses a preparation method of a reusable coating carrier. The method comprises the following steps: firstly, respectively etching the surface of the carbon felt by adopting an acid solution, then removing oxygen-containing functional groups such as-COOH and C = O on the surface of the carbon felt through alkali washing, and carrying out ultrasonic assistance to prepare the deoxygenated carbon felt. And then, depositing a hydrophobic layer on the surface of the deoxygenized carbon felt by using an electrochemical deposition method to obtain the surface-passivated hydrophobic carbon felt. The carbon felt has excellent hydrophobic and oleophylic properties, and a large number of evaporation agents can be attached to the carbon felt. Compared with the prior art, the coated pill can still stably play a role after the prepared pill is placed in a normal-temperature environment for as long as three months. The carrier material can s
