“…Likewise, the [O]/[C] and [N]/[C] atomic ratios on the particle surface decreased from 0.21 to 0.10 and from 0.07 to 0.01 for the polyimide film, respectively. Therefore, nitrogen atoms can be released more easily than oxygen atoms, contrary to the case of thermal carbonization [9,10].…”

“…The energy lost by the ion per unit path length, dE/dR, is related to the nuclear stopping power, S n (E), by the relationship: 8 where D is the atomic density of the target. The energy spectra were transformed into the depth profiles using the stopping powers calculated with the simulation from the SRIM.…”

“…In the case of the PI film the carbonization effect was observed, which makes these results consistent and extendable to all polymeric film. 6,8 The XPS spectra were analyzed into the component peaks. The XPS results after peak analysis of the untreated PI film are shown in Figure 4.…”

Surface modification and characterization of N+ ion implantation on polyimide film

The effects of N + ion implantation on surface structures and properties of polyimide films were investigated. The polyimide films were modified by 100 keV ions using a N + source at flow rates ranging from 5 × 10 14 to 5 × 10 17 ions/cm 2 with an ion current density of 10 µA/cm 2 . After the ion treatment, the chemical structures and morphology of the surfaces were examined in detail by X-ray photoelectron spectroscopy and scanning probe microscopy, respectively. The implantation of N + ions not only destroyed the chemical bonds as a result of random collisions by the incident ions and the energy transfer to the polymer atoms but also roughened the surface of the polyimide film. The roughness of the polyimide surface increased with increasing ion fluence, and the contact angle of the polyimide surface with water decreased.

“…When the PI films were irradiated with Si ions, chain scis-026101-2 sion occurs and some volatile degradation products, mostly low mass, hydrogen, nitrogen and oxygen rich molecules, escape from the PI films. [12] Thus the contents of O and N decrease significantly from the result of RBS. Because the variation of H content can not be observed by the method of RBS, we do not discuss it here.…”

Structures of polyimide (6051) films modified by irradiation of 2.0 MeV Si ions with different fluences are studied in detail. Variations of the functional groups in polyimide are investigated by attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and Raman spectroscopy. The results indicate that the functional groups can be destroyed gradually with the increasing ion fluence. The variations of structure and element contents are characterized by x-ray diffraction (XRD), Rutherford backscattering spectrometry (RBS) and xray photoelectron spectroscopy (XPS). The results indicate that the contents of N and O decrease significantly compared with the original samples, some graphite-like and carbon-rich phases are formed in the process of irradiation.
