Highly Concentrated Ozone Gas for Preparing Wettable Polyimide Surface

Highly concentrated ozone gas, of greater than 20%, was applied, for the first time, in order to obtain a stable wettable polyimide film surface. The water contact angle of the polyimide film surface decreased from 60° to nearly 20° after exposure to the highly concentrated ozone gas. The increase in the small water contact angle during storage in ambient air was very gradual, i.e., 5° for over one month. Scanning electron microscopy and the atomic force microscope showed that surface roughening simultaneously occurred. Since the X-ray photoelectron spectra showed an increase in oxygen concentration at the polyimide film surface, the highly concentrated ozone gas is considered to produce a wettable surface by the significant oxidation of the polyimide film chains on the surface.
