Abstract

The invention discloses an optimization method for a carbon nanotube and metal copper composite electroplating process in the field of micro / nano technology. In an acid copper plating mode, copper sulfate and carbon nanotubes are mixed to serve as electroplating solution, the electroplating bath is added with polyacrylic acid serving as a dispersing agent, and then is poured into an electroplating tank, and electroplating is carried out under ultrasonic environment. The carbon nanotubes are firmly combined with the metal copper, and are uniformly distributed on a composite coating, and the quality of the composite coating is improved in the aspects of quantity and uniformity of the carbon nanotubes.
