Exposure to RF plasma in argon, oxygen or ammonia has converted the normally hydrophobic surface of ePTFE tubing to a stable hydrophilic surface. The change has been maximised by statistical selection of the plasma parameters and has been analysed by contact angle measurements with three liquids, in order to obtain the dispersive and polar components of the surface energy, and by XPS. Argon produced the most hydrophilic surfaces (and oxygen the least) due to a much-increased polar component of their surface energy. © 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
