Surface characteristics of thin films prepared by plasma and electrochemical polymerizations

A comparison is made of the surface characteristics of thin films prepared by plasma and electrochemical polymerizations. Films prepared by the two methods have similar surface energies and composition. The films produced by the plasma process are much smoother, although this difference does not effect the surface energy. The electrochemically prepared films, which are known to be electroactive, show a small change in their wettability when the film is switched from the neutral to the ionic form. © 1984 American Chemical Society.
