Abstract

X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy were employed to investigate the effects of the ion beam implantation upon the chemical bonding and the final microstructure in the irradiated polyimide layer. XPS results show an increase of graphite cells with irradiation dose until a threshold is reached. A decomposing approach of data analysis for the experimental Raman spectra further discloses that the implantation parameters, i.e., dose, beam current density, and target temperature, play important but different roles in the formation of the final structure. By the current spectroscopic investigation, a deeper insight has been achieved into the origin of the enhanced conductivity, which shows the conductivity of modified layers are partly, even mainly, determined by their inner established order. This conclusion may serve as a guide in conductive polymer preparations.
