SURFACE MODIFICATION OF POLYMERS INDUCED BY ION-IMPLANTATION

It was found from the IR and UV-visible spectra, that the ion implanta tion into polymers results in the breakage of molecular chain, creatio n of double bonds and oxidation, which is connected with formation of carbonyl groups. The considerable increase of the electrical conductiv ity after the ion implantation was observed in all studied polymers. T his increase of the conductivity was essentially caused by the increas e of conjugated double bonds. In unpolar polymers, the increase of sur face free energy resulting in enhancement of polarity of unpolar polym er was found.
