Abstract (en)

[origin: WO0119903A1] A method for modifying a polymer surface is provided. Polymers are surface-modified by hydrogen ion assisted reaction and thereby the layers under the surface are converted to hydrophilic functional groups. Also, the present invention is a new method of generating a new kind of chemical bond on the surface and inner layers by damaging C-H or C-H-O bond on the polymer surface using hydrogen ions, while introducing oxygen, a reactive gas, on the surface.
