Figure 1From: Properties of silver nanostructure-coated PTFE and its biocompatibilityDependence of contact angle on sputtering time for pristine (deposition time 0 s) and silver-coated PTFE. Contact angle was determined immediately after Ag deposition (as-sputtered), after 14 days from the Ag deposition (relaxed), and on annealed and relaxed samples (annealed).Back to article page
