• multifunctional behavior of polymer systems. Keywords: ERDA; graphene oxide; ion implantation; photocatalysis; polyimide; RBS; Introduction Silver ion implantation is an effective strategy for controlling modification of the physicochemical properties of polymers and graphene-based materials. This method allows

• detection analysis (ERDA). The other analytical methods used were Raman spectroscopy, Fourier-transform infrared spectroscopy and X-ray photo-electron spectroscopy (XPS). The electrical properties were investigated by the two-point method. The photocatalytic properties were tested in a dark chamber by

• implantation primarily affects subsurface layers, leading to bulk modifications with more gradual structural changes and less surface sputtering. The details of the energy stopping powers at the depth of ion implantation are given in Figure 1. Elemental characterization by RBS and ERDA The elemental
