Why can a nanometer-thick polymer coated surface be more wettable to water than to oil?

Why can a nanometer-thick polymer coated surface be more wettable to water than to oil?

Although surfaces more wettable to water than to oil are highly desirable in many important applications, such surfaces have been rarely reported and the underlying mechanisms remain unclear. Here we report our recent experimental results indicating that the peculiar wetting behavior is kinetic in n...

Zusammenfassung:Although surfaces more wettable to water than to oil are highly desirable in many important applications, such surfaces have been rarely reported and the underlying mechanisms remain unclear. Here we report our recent experimental results indicating that the peculiar wetting behavior is kinetic in nature and results from the combination of nanoscale and interfacial phenomena.
