“…Deuteration does not significantly change the electronic orbitals and electronic bonds in the material. During VUV photons irradiation, optically allowed electronic singlet-singlet transitions are predominant at wavelengths of about 140 nm and above (Skurat 2003). Chemical transformations are mainly caused by reactions of these excited singlet states, which are very similar in both a-C:H and a-C:D materials.…”

“…It decreases during irradiation. This decrease is explained not only by consumption (depletion) of CH 3 and CH 2 groups, but also by accumulation of conjugated photolysis products, which are able to "protect" the deeper layers by a mechanism of electronic energy transfer (e.g., Skurat 2003).…”

“…This can be explained as follows: C C bonds are formed by the abstraction of hydrogen, known as the dominant mechanism during VUV irradiation of hydrocarbon polymers. [11,12,19,21,22,28,34,35] For example, the main primary reaction involved in the VUV photolysis of LDPE is the following:…”

“…In the case of BOPP, unsaturation may also result from polymer chain scission, accompanied by the formation of lower molecular weight products: [12,22,34,35] ð13Þ ð14Þ…”

“…At 157 nm PTFE has a strong absorbance. [32] The corresponding electronic transition is mainly assigned to the excitation of C-C bonds, [33] which leads to a photo-dissociation of the C-C single bond, [34] indicating a decomposition of the polymer into monomers and to carbon by defluorination, which is expected as the photon energy at 157 nm is higher than the binding energy of a carbon to fluorine bond. [35] This is also expressed in the XPS C1s level spectra in Figure 6(b).…”
