摘要: A method for fabricating a membrane is disclosed, to provide both hydrophilicity and hydrophobicity to predetermined positions of a surface of a single membrane. The method for fabricating a membrane includes: preparing a template with nano-scale holes formed on its outer surface; coating a polymer material on a predetermined pattern region of the outer surface of the template; attaching a hydrophilic film on the outer surface of the template; and removing the template from the hydrophilic film.
