Very thin (3 µm) polyethylene terephthalate (PET) foils were irradiated with 150 keV Na + ions with the fluences in the range from 1 × 10 14 cm −2 up to 1 × 10 16 cm −2. Modification of chemical structure of the implanted polymer was studied with the Fourier transform infrared and Raman spectroscopies. Destruction of numerous chemical bonds as well as formation of carbon clusters made of sp 2 hybridised C atoms and conducting cluster networks were demonstrated. The increasing presence of chain structures in the graphite-like carbonised layer is pointed out as the G band shift and decrease of D band could be seen as irradiation fluence rises. The large increase of the modified sample absorbance with the implantation fluence in the UV-VIS region was observed. The decrease of optical band-gap energy from 3.95 eV for the pristine sample down to 0.7 eV for the most heavily treated sample was estimated using the Tauc plot. Reduction of bulk resistivity by more than 8 orders of magnitude is shown in the case of the sample implanted with the fluence 1 × 10 16 cm −2. The sheet resistivity of the sample was also reduced by 5 orders of magnitude. The effect was observed on both sides of the sample, probably as the result of chemical transformations due to local increase of the polymer foil temperature. The moderate increase (15-200%) of the dielectric constant is observed in the frequency range up to 1 MHz and the change rises with the implantation fluence.

“…There were studies on the modification of polyurethane (PU) by N + and Ar + [12,13,18], polystyrene by Ar + [32], polyethylene (PE) by, e.g., H + , He + , Ar + , Xe + , and Ti + [33][34][35][36][37], polyaryletheretherketone (PEEK) by N + [38][39][40], polycarbonate (PC) by Ar + and Cu + [41][42][43], poly(allyl diglycol carbonate) (CR-39) by Ar + and Au + [21,44,45], polymethylmethacrylate (PMMA) by Au + , Ag + , B + , and C + [46][47][48]. Many reports concerning the modification of irradiated elastomers, e.g., acrylonitrilebutadiene rubber (NBR), ethylene propylene diene monomer (EPDM), and polytetrafluoroethylene (PTFE) irradiated by He + [49][50][51][52][53] were also delivered. Last but not least, much effort has gone into the investigations of implanted polyethylene terephthalate (PET) [54][55][56][57][58][59][60][61][62].…”

Modification of PET Foil by 150 keV Li⁺ Ion Implantation

Very thin (3 µm in thickness) polyethylene terephthalate polymer foils were implanted with 150 keV Li + with fluences in the range from 1×10 14 cm −2 up to 2×10 16 cm −2 . Modification of the irradiated polymer microstructure was studied with the Fourier transform infrared spectroscopy and Raman spectroscopy. Breaking of a variety of chemical bonds followed by the formation of carbon clusters made of sp 2 C was proved. The dominance of the rings in the carbonized, graphite-like subsurface layer is demonstrated based on the fact that the G band prevails in the Raman spectra for larger Li + fluences. The rise of the absorbance within 200-800 nm is observed. Tauc's plots analysis enables the estimation of optical bandgap values that decrease from 3.95 eV (pristine polyethylene terephthalate) down to 1.4 eV (fluence of 2 × 10 16 cm −2 ). This change is not as dramatic as in the case of heavier projectiles like K + or Na + . Reduction of surface resistivity by more than 2 orders of magnitude is observed in the case of the sample irradiated with the fluence 1 × 10 16 cm −2 , and this effect is much smaller than that induced by the heavier projectile bombardment with the same fluence. topics: polymers modification, ion implantation, polyethylene terephthalate (PET)
