Abstract :
Polyethylene terephthalate (PET) has been modified by metal ion implantation with a dose range from 1×1016 to 2×1017 ions/cm2 using a metal vapor vacuum arc (MEVVA) source. The resistivity of implanted PET decreased obviously with an increase of ion dose. When the metal ion dose of 2×1017 cm-2 was selected, the resistivity of PET could be less than 0.1 ΩM. The results show that the conductive behavior of a metal ion implanted sample is obviously different from nonmetal ion-implantation one. The resistivity of metal ion implanted polymer is very stable. The resistivity slightly changes when retention time of the implanted PET is over 1000 days. The three-layer structure appears and it is believed that the change would cause the improvement of the properties. The modification mechanism of PET is discussed.
