“…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

“…The asymmetry parameters evaluated from core-electron line-shape analysis yield a value of the order of 0.04 ± 0.01. Amor et al [12] studied the XPS analyses of reference and carbon dioxide plasma treated polyethylene terephthalate (PET). Significant chemical modifications were outlined in the treated PET surface in comparison with the reference one.…”

“…Surface modification techniques such as ion implantation, [4] laser ablation, [5,6] plasma treatments, [7][8][9][10][11][12] ultraviolet-ozone (UV/O 3 ) cleaning, [13] and wet-processes [14] have been utilized to overcome this problem. Most of these processes can change the wettability and the chemical functional groups while increasing the surface roughness.…”

We studied the effects of 172 nm Xe 2 * excimer lamp irradiation on polyethylene terephthalate (PET) surfaces. Two kinds of techniques were applied: vacuum ultraviolet (VUV) light irradiation and VUV irradiation in the presence of oxygen gas (VUV/O 3 ). The modified PET surfaces were investigated by using contact angle measurements which enabled the surface free energy to be calculated, X-ray photoelectron spectroscopy (XPS), nano-thermal analysis (nano-TA), and atomic force microscopy (AFM). The surface free energy increased significantly after the treatments. The results of XPS analysis showed that the elemental ratio of oxygen on the surface increased, whereas that of carbon decreased. From the deconvoluted C1s and O1s spectra, it was revealed that new oxidized functional groups such as alcoholic and carboxyl groups were generated. The nano-TA results showed that a low melting temperature (T m ) layer had formed on the VUV and VUV/O 3 treated PET surfaces. The results of AFM measurements showed there were no remarkable changes after the treatments compared with untreated PET. In summary, the VUV and VUV/O 3 treatments using a Xe 2 * excimer lamp not only change the surface functionalities but also reduce the T m of the PET surfaces without significantly affecting the surface morphologies.
