X-ray photoelectron spectroscopy studies of plasma-modified PET surface and alumina/PET interface

Comparative study on the performance of pyrolyzed and plasma-treated iron(II) phthalocyanine-based catalysts for oxygen reduction in pH neutral electrolyte solutions

“…The second component at 286.0 eV can be associated to N-C N [20]. The 287.5 eV peak can be ascribed to carbon bound to oxygen by two oxygen bonds (C O, N C O) [21]. A shake-up satellite appeared at 290.6 eV.…”

Nucleation and growth of gas barrier aluminium oxide on surfaces of poly(ethylene terephthalate) and polypropylene: effects of the polymer surface properties

“…chemisorption of AlOO on to the sites having carbonyl groups. Evidence from X-ray photoelectron spectroscopy by Cueff et al 27 suggests that there are chemical bonds formed between aluminium and oxygen of the carbonyl group in PET:…”

Creating Biointerface on Polymer by Plasma-Initiated Graft Polymerization

“…Figure 3 (b)-(d) shows XPS C 1s spectra obtained from (b) the untreated PET surface, (c) the PET surface after Ar plasma treatment, and (d) the PET surface after Ar plasma followed by hydrophilic AA modification. The C 1s spectrum of the untreated PET surface (Figure 3 (b)) is deconvoluted into three peaks corresponding to C-C/C-H groups that arise from adventitious carbonaceous contamination group (peak C1 at 284.7 eV), carbon atoms singly bonded to oxygen (peak C2 at 286.5 eV), and ester carbon atoms (peak C3 at 289.1 eV) [12][13][14][15][16][17][18][19][20]. However, the C 1s spectrum (Figure 3 (c)) reveals that the PET surface was chemically altered by the Ar plasma treatment.…”
