Fabrication of a superhydrophobic surface by straightforward immersion for copperplate artwork protection.

With the background of contemporary art, using comprehensive materials to create artworks is becoming more and more common. The new era of digital image-based copperplate artworks, using photosensitive lithography, has given traditional art forms new life and greater popularity in the digital age. However, the patterns and textures of the works created by the new techniques are generally shallow, and the copper surface is easily damaged and loses its aesthetic value, which makes it a practical problem to protect such works more effectively.
