Methods for reforming polymer surface for improved wettability |
| abstract |
The present invention relates to a method for reforming the surface of polymer, especially to a method for providing hydrophilicity or increasing hydrophobicity by reforming the surface of polymer or polymer membrane. The present invention is a method for reforming the surface of polymer membrane by irradiating it with energized ionic particles under the vacuum condition. The method including the steps of: a) manufacturing polymer membrane, including a surface activated, by inserting polymer membrane into a vacuum chamber, and by irradiating energized ionic particles on the surface of polymer membrane with an ion beam under a high vacuum; and b) manufacturing polymer membrane treated with a reactive gas on the surface of membrane, including the activated surface of step a), by infusing the reactive gas into a vacuum chamber after energized ionic particles of step a) have been irradiated. The methods in the present invention can achieve their objects to reform the surface to provide hydrophilicity of hydrophobicity without deteriorating mechanical properties of the polymer membrane. Additionally, it can also contribute to an improved working environment and readily accommodate mass production techniques because the surface reforming of polymer membrane is a relatively simple technique that does not employ solvents. |
