Structured surface displaying microroughness or nanoroughness are significantly more hydrophobic than smooth surfaces. This study aims to produce nanostructured surface on ePTFE surface by plasma etching process in order to further enhance their hydrophob Structured surface displaying microroughness or nanoroughness are significantly more hydrophobic than smooth surfaces.
