“…Other prominent PMMA bands present in the spectrum correspond to the C-O moiety at 1241 cm −1 (symmetric vibration for C-C-O combined with CH deformation), 1193 cm −1 (asymmetric vibration for C-O-C group with internal CH deformation) and 987 cm −1 (C-O-C combined with OCH 3 group). Finally, the band at 1727 cm −1 was also observed, corresponding to the symmetric stretching vibration for C=O group [28]. Table 1 presents in detail all the bands and their assignments for each hybrid film.…”

“…Additionally, Figure 6 shows the IR spectra for the polymer hybrid films, in which the bands of C=Oketo form, C=Oenol, C=C, and Ru-O are evident. However, the band corresponding to C aromatic-H (3049-3065 cm −1 ) was not distinguished, due to the presence of the intense PMMA bands corresponding to (i) the asymmetric stretching vibration for CH in aliphatic group (2850 cm −1 ) and (ii) the combination band involving CH and CH3 group (2951 cm −1 ) [28]. Other prominent PMMA bands present in the spectrum correspond to the C-O moiety at 1241 cm −1 (symmetric vibration for C-C-O combined with CH deformation), 1193 cm −1 (asymmetric vibration for C-O-C group with internal CH deformation) and 987 cm −1 (C-O-C combined with OCH3 group).…”

Polymeric hybrid films, for their application in organic electronics, were produced from new ruthenium indanones in poly(methyl methacrylate) (PMMA) by the drop-casting procedure. Initially, the synthesis and structural characterization of the ruthenium complexes were performed, and subsequently, their properties as a potential semiconductor material were explored. Hence hybrid films in ruthenium complexes were deposited using PMMA as a polymeric matrix. The hybrid films were characterized by infrared spectrophotometry and atomic force microscopy. The obtained results confirmed that the presence of the ruthenium complexes enhanced the mechanical properties in addition to increasing the transmittance, favoring the determination of their optical parameters. Both hybrid films exhibited a maximum stress around 10.5 MPa and a Knoop hardness between 2.1 and 18.4. Regarding the optical parameters, the maximum transparency was obtained at wavelengths greater than 590 nm, the optical band gap was in the range of 1.73–2.24 eV, while the Tauc band gap was in the range of 1.68–2.17 eV, and the Urbach energy was between 0.29 and 0.50 eV. Consequently, the above comments are indicative of an adequate semiconductor behavior; hence, the target polymeric hybrid films must be welcomed as convenient candidates as active layers or transparent electrodes in organic electronics.

“…For p(AAco-MMA) sample (Fig.1a), a broad peak in the range 3310-3396 cm − 1 appears inferring the presence of stretching vibrations of O-H associated with presence of a weak band at 2934 cm − 1 ascribing to the C-H stretching vibrations[36]. The sharp and intense peaks at 1723 cm − 1 and 1658 cm − 1 are assigned to the C = O stretching vibrations[37]. Two pronounced peaks assigned to the symmetrical and asymmetrical (O = C-O) of carboxylate ions appear at 1397 cm − 1 and 1440 cm − 1 , respectively.…”

In this study, the conventional fibrous structure of poly (acrylic acid-co-methyl methacrylate) chains is reoriented and significantly joined to form a layer-like morphology by being hybridized with carboxymethyl cellulose. Such innovative hybrid polymeric material is analyzed using various techniques, including, FTIR, XRD, swelling and contact angle studies, DLS, AFM, and SEM. Removal efficiency of such hybrid polymeric system is scrutinized in treatment of dyeing wastewater. Removal of cationic safranin dye from wastewater is best described by Langmuir model and pseudo-first-order kinetic approach, adopting exothermic adsorption progression with highly developed capacity (~ 59.47 mg/g) and accelerated rate (~ 1.06 h− 1). Such hybrid polymeric system exhibits elevated removal efficiency of ca. 90% within 10 min for at least five-consecutive cycles. Besides, such hybrid polymeric system considers a potential platform to stabilize Ag nanoparticles upgrading their accessibility to eradicate Escherichia coli and Staphylococcus aureus bacteria. Increased demand for exploring innovative materials in the field of wastewater treatment requalifies the hybrid O-rich polymeric systems to a magnificent adsorbing and biocidal performance.
