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. Not only that, the hydrophobicity provides the polymer substrate with the ability for mechanical adhesion in the formation of an adhesive interface, resulting in an excellent adhesive strength. 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.
