Figure 5: FTIR ATR spectra of LDPE after PIII treatment. Thick array shows fluence increase of PIII treatment: from untreated to 1015, 2 × 1015, 5 × 1015, 1016, 2 × 1016 ions/cm2. The spectra were recorded after stabilization during 2 weeks storage time after PIII treatment. The intensity of unsaturated and oxygen-containing group lines increases with fluence of PIII.
