“…Since the O 1s spectra of all PET/CDP nanofibers (PET/␣-CDP, PET/␤-CDP and PET/␥-CDP) are similar to each other, those XPS data acquired for PET/␣-CDP and PET/␤-CDP nanofibers were not given. The O 1s spectrum of unmodified PET nanofibers clearly represent the two types of oxygen atoms within the ester groups; -bonded oxygen (C O * ) and -bonded oxygen (C O * ) at binding energies of 531.54 and 533.12 eV, respectively [32][33][34][35]. The ratio of these peaks is 56.2:42.1, which is in reasonable agreement with the theoretical ratio of 50:50 [36].…”

Cataloged from PDF version of article.Surface modified electrospun polyester (PET) nanofibers with cyclodextrin polymer (CDP) were produced (PET/CDP). CDP formation onto electrospun PET nanofibers was achieved by polymerization between citric acid (CTR, crosslinking agent) and cyclodextrin (CD). Three different types of native CD (α-CD, β-CD and γ-CD) were used to form CDP. Water-insoluble crosslinked CDP coating was permanently adhered onto the PET nanofibers. SEM imaging indicated that the nanofibrous structure of PET mats was preserved after CDP surface modification process. PET/CDP nanofibers have shown rougher/irregular surface and larger fiber diameter when compared to untreated PET nanofibers. The surface analyses of PET/CDP nanofibers by XPS elucidated that CDP was present on the fiber surface. DMA analyses revealed the enhanced mechanical properties for PET/CDP where PET/CDP nanofibers have shown higher storage modulus and higher glass transition temperature compared to untreated PET nanofibers. The surface area of the PET/CDP nanofibers investigated by BET measurements showed slight decrease due to the presence of CDP coating compared to pristine PET nanofibers. Yet, it was observed that PET/CDP nanofibers were more efficient for the removal of phenanthrene as a model polycyclic aromatic hydrocarbon (PAH) from aqueous solution when compared to pristine PET nanofibers. Our findings suggested that PET/CDP nanofibers can be a very good candidate as a filter material for water purification and waste treatment owing to their very large surface area as well as inclusion complexation capability of surface associated CDP

“…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.…”

Hydrophilic modification of polyethylene terephthalate (PET) was successfully demonstrated by surface wave plasma treatment followed by graft polymerization with various monomers such as acrylic acid (AA), (2-hydroxyethyl) methacrylate (HEMA), and styrene (St) in the vapor phase. The plasma treatment did not physically damage the PET surface. The graft reactions were confirmed by water contact angle measurements and X-ray photoelectron spectroscopy (XPS). The water contact angles of the PET surface modified with hydrophilic AA and HEMA monomers decreased from approximately 80° before treatment to less than 35°, and the hydrophilicity of the PET surface modified by hydrophilic AA and HEMA monomers was maintained for 70 h. 3T3 fibroblast cells were cultured on the modified PET surfaces to investigate the bioactivity of the modified PET surfaces.
