N2 - The fabrication of polytetrafluoroethylene (PTFE) and polyimide (PI) layered films has been demonstrated by high temperature soft electron beam (soft-EB) irradiation techniques. The PTFE dispersion has been coated by wire-bar coating equipment on PI thin film. The PI/PTFE layered films were irradiated by EB at 330°C±3°C in nitrogen gas atmosphere. Characterization of soft-EB irradiated PI/PTFE films have been performed by X-ray photoelectron spectroseopy (XPS), thermal analysis (DSC and TGA), and so on. According to XPS analysis on PTFE coated side, the atom ratio of F/C, H/C and N/C were 2.44, 0.04 and 0.06, respectively. Thus, it was found the fluorine coaled on PI surface, that is, PTFE molecule has been reacted with PI polymer chains by high temperature soft-EB irradiation. Moreover, the obtained hybrid films showed the good adhesive properties and lower crystallinity.
