“…The peak at 1239 cm-1 was due to C-O-C stretching with bands at 2950.93 and 2993.21 cm-1 belonged to C-H stretching vibrations. It can be deduced from these data that all the groups showed consistent results with the current literature [46][47][48][49][50].…”

Purpose: Polymers are used in dentistry on a daily basis due to their mechanical, functional and aesthetic properties. However, such biomaterials are subject to deterioration in the oral environment. Thus, this study aimed to evaluate the structural properties of five commonly used dental polymers to determine their best clinical indications. Methods: Four hundred-fifty samples of five dental polymers (polyethylenterephthalat -glycol modified (PG), polymethyl methacrylate (PA), ethylene vinyl acetate(E), polycarbonate (PC), polyetheretherketone (PK) were prepared to investigate their thermal, structural and chemical characteristics using energy dispersive spectroscopy (EDS), Fourier transform infrared analysis(FTIR), scanning electron microscopy (SEM), differential scanning calorimetry(DSC), thermogravimetric analysis(TGA), X-ray diffraction(XRD), and Shore D hardness test. Data were analyzed using one-way ANOVA, Tukey's HSD, and Levene's tests (α=0.05). Results: PK (87.2) and PA (82.4) displayed the highest hardness values and smooth surfaces, as observed with SEM (p<0.001). Silica was detected in PK, PA, and E by EDS and XRD. The highest glass transition temperature was recorded for PC (145.00±2.00°C) and PK (143.00±1.87°C), while the lowest value was measured for E (50.00±2.12°C)(p<0.001).The highest mass loss was detected for PG (91.40±1.40%) by TGA. Conclusions: PA and PK polymers can be used for stress-containing treatments due to their mechanical properties. These two materials are also advantageous in terms of plaque accumulation as these polymers reveal smoother surfaces than other groups. Insufficient physical and thermal properties require the use of E with caution and only in limited clinical indications.

“…The missing T g onset point in the region 80–85°C indicated that residual MMA monomer was consumed. In addition, it was suggested that the presence of RhB in the SH bleed also shifted the T g of pure polymerized acrylic resin to higher temperatures and was superposed with the exothermic cured peak. This result, which implies further polymerization of MMA, is in agreement with the FTIR analysis, which also revealed bands assigned to poly(DCPD) and PMMA.…”

This article presents a novel processing method of a self‐healing acrylic thermoplastic material starting from a healing agent in solution form. The self‐healing system consisted of a solution of the healing agent dicyclopentadiene (DCPD) in dimethylformamide (DMF) and a solution of the catalyst bis(tricyclohexylphosphine) benzylidene ruthenium (IV) dichloride (called Grubbs' catalyst) in dichloromethane (DCM). Hollow glass tubes filled with the self‐healing components were incorporated into autopolymerizing acrylic resins. The one set of tubes was filled with a solution of DCPD (containing the dye Rhodamine B as a marker) and the other set with a solution of Grubbs' catalyst in dichloromethane. FTIR and DSC analyses revealed that a poly(DCPD) film formed at the healed interface. The low energy impact tests of the samples showed a recovery of 83% after 4 days. The benefits of the Grubb's catalyst solution are twofold; besides the repair of the cracks, which is common for such a system, the reaction could decrease the content of residual monomer in the acrylic resin, which could reduce diffusion of residual monomer out of the resins.

“…The spectra showed two characteristic bands at 2997 and 2952 cm −1 , which is correspond to the CH bond stretching vibrations of the CH 3 and CH 2  groups, respectively . The CO carbonyl/carboxyl band at 1730 cm −1 and other peaks corresponding to the matrix polymer PMMA were preserved in the spectra of C1 ‐PMMA and C2 ‐PMMA nanofibers . Both spectra also had a band at 1449 cm −1 that has been assigned to the bending vibration of the CH bonds of the CH 3 group …”

“…FTIR spectrum of PMMA fibers doped with C2 also showed the formation of new vibrational bands of rather weak intensities, appearing at 1590, 988, and 750 cm −1 . These weak bands confirm that C2 did reacts with the functional groups of PMMA.…”

Two bis-chalcone derivatives, (2E,6E)-2,6-bis[(thiophen-2-yl)methylene]cyclohexanone (C1) and (2E,6E)-2,6-bis[(furan-2yl)methylene]cyclohexanone (C2)-based electrochromic (EC) nanofibers were produced in the presence of poly(methyl methacrylate) (PMMA) as supporting polymer using the electrospinning technique. The scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy were used to examine morphology and chemical compositions of nanofibers before and after stability test. SEM images of the obtained smooth and bead-free nanofibers before the stability test showed that both bis-chalcone derivatives were homogeneously dispersed on the surface of the electrospun nanofibers. Nanofibers of bis-chalcone derivatives were characterized with Fourier-transform infrared spectroscopy. The electrochemical and EC properties of these bis-chalcone derivatives were investigated. The C1-PMMA nanofiber-based electrochromic device (ECD) showed higher DT max (41.47%) than that of the C2-PMMA nanofiberbased ECD (4.67%) during coloration/bleaching at 715 nm. The switching times for coloration and bleaching of C1-PMMA nanofiber-based ECD were found to be 4.42 and 1.12 s, respectively, and the coloration efficiency was 136.18 cm 2 /C. Repeated cyclic voltammograms and 1000 cycles of chronoamperometric measurements of the bis-chalcone derivatives indicated that ECDs have long-term redox stability.
