Abstract: The present invention relates to a polymer substrate that contains polycrystalline pores formed on a surface thereof and a method of preparing the same by a surface treatment. The polymer of the present invention contains, on its surface, pores with a polycrystalline structure, and, thus, it exhibits hydrophobicity that accounts for a high fouling resistance.

Also, the method of surface treatment to prepare such a substrate is advantageous in that it can treat a large area of a surface economically while not using substances that are harmful to the human body and environment.
