“…Before coordination, the C 1s XPS spectrum of PMMA consists of three types of carbon atoms, that is, CC or CH atoms at 285.0 eV, CO atoms at 286.6 eV, and CO atoms at 288.8 eV. After coordination, the CO component at 288.8 eV is significantly decreased, thus indicating coordination between the CO bonds and the copper ions 26. On the other hand, the peaks at 163.0 and 161.8 eV in the S 2p XPS spectrum before coordination correspond to the 2p 1/2 and 2p 3/2 orbitals of divalent sulfide ions (S 2− ) 27.…”

“…After coordination, the C=O component at 288.8 eV is significantly decreased, thus indicating coordination between the C=O bonds and the copper ions. [26] On the other hand, the peaks at 163.0 and 161.8 eV in the S 2p XPS spectrum before coordination correspond to the 2p 1/2 and 2p 3/2 orbitals of divalent sulfide ions (S 2À ). [27] After coordination, the peak at 163.0 eV shifts to a higher binding energy of 168-169 eV, thus confirming coordination between the divalent sulfide ions and the copper ions, owing to copper-catalyzed radiation damage, that is, the radiation-induced surface oxidation of sulfur in the presence of ligated copper atoms.…”

Inorganic graphene analogues (IGAs) are a huge and fascinating family of compounds that have extraordinary electronic, mechanical, and thermal properties. However, one of the largest problems that face the industrial application of IGAs is their poor processability, which has led to a "bottlenecking" in the development of freestanding, large-area, IGA-based thin-film devices. Herein, we report a facile and cost-efficient method to chemically modify IGAs by using their abundant coordination atoms (S, O, and N). Taking MoS2 as an example, we have prepared homogeneous "solution" systems, in which MoS2 nanosheets are chemically cross-linked through a carboxylate-containing polymeric ligand, poly(methyl methacrylate) (PMMA), by copper-ion coordination. Bonding interactions between C=O bonds and sulfur atoms through copper ions were confirmed by various characterization techniques, such as UV/Vis, FTIR, and Raman spectroscopy and XPS. By using our method, freestanding MoS2 paper with significantly improved mechanical properties was obtained, thus laying the basis for the mass production of large-area MoS2-based thin-film devices. Furthermore, copper-ion coordination was also applied to MoS2/PMMA nanocomposites. Direct and strong nanofiller/matrix bonding interactions facilitate efficient load transfer and endow the polymeric nanocomposites with an excellent reinforcement effect. This method may pave a new way to high-strength polymeric nanocomposites with superior frictional properties, flame retardance, and oxidation resistance.

“…Nevertheless, the spectra indicate that most of the IR spectra are mainly dominated by the bands due to the basic polymer (bottom spectrum). According to the literature data, the infrared spectrum of the basic polymer of these clear coat automotive paints could probably be identified as poly(methyl)methacrylate resin [7][8][9]. Its monomer unit consists of C=O, C−O, CH 2 and CH 3 functional groups.…”

Raman and infrared spectroscopy are two complementary spectroscopic techniques that can produce fast, efficient and accurate detection of the pigments and/or binders used in automotive topcoats. Micro-Raman spectroscopy, due to its non-destructiveness, has been extensively used for identification of pigments and dyes in forensic investigation of hit-and-run accidents. This technique provides very useful and significant information from very small samples of evidence without any previous preparation of the sample. The recorded Raman spectra of the unknown/ suspected samples can be compared with a spectrum of the referent sample, which can coincide with the one already existing in the Raman database of pigments. In order to form our own spectral database of automotive paints for forensic investigations in hit-and-run offences in Republic of Macedonia, an investigation of automotive topcoats of different origins was carried out. In our previous study, pigments in some automotive topcoats, produced by Mobihel, have been identified using micro- Raman and FT-IR spectroscopy. In the present study, we report micro-Raman and FT-IR spectra of ten base coat automotive topcoats, as well as some of their mixtures, produced by Glasürit. In order to demonstrate the availability and/or the advantages of the micro-Raman spectroscopic technique in forensic investigation in road accidents, four successfully solved cases from the police investigation in hit-and-run accidents are presented in this work.
