Post Ar plasma treatment recovery.

<p>Monitoring recovery of surface potential (a, c, e) and contact angle (b, d, f) after 60 sec Ar plasma treatment for RTV 655, RTV 615, and Sylgard 184. Recovery conditions under vacuum and at atmospheric pressure were also compared. The surface hydrophobicity of all three polymers recovered within the first twelve hours while the surface potential remained at values close to zero even 48 hrs after treatment. Recovery rate appears to be independent of the storage conditions of vacuum versus ambient.
