United States Patent Application

An atmospheric cold plasma brush was used to treat the surfaces of polymers. The surface properties of plasma-treated polymers were compared to those of the corresponding untreated polymers by static water contact angle measurements. Surface treatment usually resulted in a decrease in the static water contact angle, indicating that the treatment resulted in a higher surface energy and surface wettability compared to the untreated polymer.
