XPS spectra. (a) A wide scan XPS spectra of the N2 the plasma-untreated and treated polymer films. The inset shows enlarged N1s XPS spectra in Figure 1. (b) High-resolution XPS spectra of N1s peaks for the plasma-treated polymer film. (c) High-resolution XPS spectra of C1s peaks for the plasma-untreated polymer film. (d) High-resolution XPS spectra of C1s peaks for the N2 plasma-treated polymer film.
