Abstract: Disclosed are a method and an apparatus for irradiating low energy ion beam on polymer. The method prepares polymer products having a surface electric conductivity range, in surface electric resistance, from 106 to 1011 &OHgr;/sq, by vacuum-irradiating the ions under relatively low energy of 50-100 keV from ion sources which generates high-current ions of several tens mA or higher, to polymer materials, such as PPO and MPPO, which are electrically insulator; precisely controls temperature so as not to thermally deform molecular configuration of the polymers; produces the products with uniform and stable conductivity in a large area; and treats the surface which improves surface hardness and modifies mechanical properties. Further, the mass-production apparatus for irradiating the ion beams is capable of commercially realizing said method. Accordingly, ions, inert gases (nitrogen, oxygen, argon, xenon, helium, etc.
