“…X-ray photoelectron spectroscopy (XPS) has been used to study changes in material surfaces which are principally changes of absolute C/O intensity ratio on polymers such as PET, [13][14][15][16] poly(L-lactic acid) (PLLA), 17 polymethylmethacrylate (PMMA) and blends of polycarbonate and acrylonitrile butadiene styrene. 18 Depth analysis of chemical bonding states of polymers is determined by photoelectron mean free path using conventional XPS 19 instruments that can be enhanced using hard XPS.…”

The photodegradation of irradiated PETG and PCCT model compounds namely Tm‐CHDM‐Tm and Tm‐TMCD‐Tm, where Tm refers to the methyl ester of terephthalic acid, CHDM refers to 1, 4‐cyclohexanedimethanol, and TMCD refers to tetramethyl‐1, 3‐cyclobutanediol, was analyzed using X‐ray photoelectron spectroscopy. Photodegradation products were characterized based on high resolution O1s x‐ray photoelectron spectroscopy (XPS) spectra and the spectra of irradiated model compounds showed a decrease in the relative intensity of CO compared to the CO peak. The percentage of CO formation in irradiated model compounds changed in proportion to irradiation time and showed that the model compound containing CHDM was slightly more UV stable than the TMCD based model compound. Photodegradation mechanisms for model compounds were proposed based on XPS spectra. In parallel studies, density functional theory calculations were performed as an approach to predict degradation products, to help interpreting the XPS spectra of model compounds and characterize the reactivity of model compounds.

“…Achieving control over the surface properties of materials widens their range of applications. Amongst the many available surface modification methods, polymer coatings are commonly applied to generate new properties at the surface of materials, such as antifouling [1][2][3], anti-corrosive [4,5], bio-sensing [6,7], heavy metal adsorbent [8,9] or fireretardant [10,11] properties. Homogeneous single-layer coatings are often preferred as they provide a single-step treatment-often by self-assembly.…”

Using low pressure plasma polymerization, nano-scaled oxygen-rich plasma polymer films (CO) were deposited onto pristine silicon wafers as well as on nitrogencontaining plasma polymer (CN) model surfaces. We investigate the influence of the nature of the substrate as well as a potential sub-surface effect emerging from the buried CO/CN interface, just nanometers below the surface. X-ray Photoelectron Spectroscopy and Timeof-Flight Secondary Ion Mass Spectrometry revealed two important phenomena that occurred during the deposition of the terminal CO layer: (1) a strong degree of oxidation, already for 1 nm nominal thickness, and (2) a gradual transition in chemical composition between the two layers, clearly indicating that effectively a vertical chemical gradient results, even when a two-step coating process was applied. Such terminal gradient film structures were used to study film stability in aqueous environments. Molecular rearrangements were scrutinized in the top-surface in contact with water and we found that the top-surface chemistry and wetting properties of the oxygen-rich termination layer matched those of thick CO reference coatings. Nevertheless, the adsorption of green fluorescent protein (GFP) was observed to be sensitive to the CO terminal layer thickness. Namely, an enhanced protein adsorption was observed for 1-2 nm thick CO layers on CN, whereas a significantly reduced protein adsorption was seen on C 3 nm thick CO terminal layers. We
