Wettability characteristics of poly(ethylene terephthalate) films treated by atmospheric pressure plasma and ultraviolet excimer light - pet film
Two drying processes of atmospheric pressure plasma (APP)
UV irradiation and 172 nm (UV)
In order to enhance the hydrophilic properties of poly (), corneal light irradiation (
The humidity change on the surface of the PET film after the process was recorded by the wet force measurement using the Wilhelmy method.
After the drying process, it was observed that the forward and backward contact points of the water decreased sharply, especially for the application exposure.
By flushing with water or aging in the air, it was found that the propulsion angle of the treated PET surface increased, while the backward propulsion angle remained almost the same.
Faster UV reduction in oil recoverytreated film.
The surface of PET film was characterized.
We discuss the effect of the drying process on the physical and chemical properties of the PET surface.
