“…Figure shows the FTIR transmittance spectra of pure PEO, pure PMMA, PEO/PMMA (90:10) blend, PEO/PMMA/KI/I 2 and PEO/PMMA/KI/I 2 / x wt% of ZnO nanorods fillers. The observed well defined IR vibrational bands of pure PEO spectrum at 1,113, 1,242, 1,280, 1,350, and 1,465 cm −1 are assigned to the COC stretching, a mixed mode of CH 2 twisting, wagging and scissoring, respectively . The vibrational bands of pure PMMA are ascribed to the CO stretching vibration (1,270–990 cm −1 ), CH bending vibration (1,450–1,350 cm −1 ), and CH 2 rocking (810 cm −1 , 750 cm −1 ).…”

In this present study, we have studied the relaxation behaviour and dynamics of charge carriers in poly(ethylene oxide; PEO)/poly(methyl methacrylate; PMMA) blend with potassium based iodide–triiodide redox couple as polymer solid electrolyte dispersed with different concentration of ZnO nanorods as fillers. Various composition of potassium iodide (KI)‐based nanocomposite (PEO/PMMA/KI/I2/x wt% ZnO nanorods, x = 0, 2, 4, 6, 8, and 10) polymer solid electrolytes (NCPSEs) films were prepared by solution casting technique. Structural properties of the prepared solid electrolytes are studied by X‐ray diffraction and Fourier transform infrared spectroscopy. Among the prepared NCPSEs, 6 wt% sample of solid electrolyte showed high conductivity of 4.698 × 10−5 S/cm. The relaxation and dynamics of charge carriers are studied by analyzing complex conductivity and dielectric permittivity through power law along with the contribution of electrode polarization and Havriliak–Negami formalism, respectively, for the prepared polymer solid electrolytes to find out their usefulness for dye‐sensitized solar cell applications. © 2018 Society of Plastics Engineers POLYM.

“…In the FTIR spectrum of PEO‐PMMA polymer blend electrolytes, the absorption peaks at 1730 cm −1 are assigned to OCH 3 deformation of PMMA. It can be observed that a new peak at 750 cm −1 may be due to the interaction between the oxygen atom of PEO and carbonyl carbon atoms of PMMA . In the FTIR spectrum of PEO‐PMMA‐KI‐I 2 /2‐MCP, the peak at 1562 cm −1 correspond to the stretching frequency of CNC group of 2‐MCP and it is clear that the intensity of peak is increased with increase in the amount of 2‐MCP.…”

“…The miscibility of components is very important for choosing of polymer blends. It is clear from the reported literatures that PEO is miscible in PMMA . PEO is chosen as the electrolyte medium because of its polar and chemically stable nature.…”

Solvents and electrolytes play an important role in the fabrication of dye‐sensitized solar cells (DSSCs). We have studied the poly(ethylene oxide)‐poly(methyl methacrylate)‐KI‐I2 (PEO‐PMMA‐KI‐I2) polymer blend electrolytes prepared with different wt % of the 2‐mercaptopyridine by solution casting method. The polymer electrolyte films were characterized by the FTIR, X‐ray diffraction, electrochemical impedance and dielectric studies. FTIR spectra revealed complex formation between the PEO‐PMMA‐KI‐I2 and 2‐mercaptopyrindine. Ionic conductivity data revealed that 30% 2‐mercaptopyridine‐doped PEO‐PMMA‐KI‐I2 electrolyte can show higher conductivity (1.55 × 10−5 S cm−1) than the other compositions (20, 40, and 50%). The effect of solvent on the conductivity and dielectric of solid polymer electrolytes was studied for the best composition (30% 2‐mercaptopyridine‐doped PEO‐PMMA‐KI‐I2) electrolyte using various organic solvents such as acetonitrile, N,N‐dimethylformamide, 2‐butanone, chlorobenzene, dimethylsulfoxide, and isopropanol. We found that ac‐conductivity and dielectric constant are higher for the polymer electrolytes processed from N,N‐dimethylformamide. This observation revealed that the conductivity of the solid polymer electrolytes is dependent on the solvent used for processing and the dielectric constant of the film. The photo‐conversion efficiency of dye‐sensitized solar cells fabricated using the optimized polymer electrolytes was 3.0% under an illumination of 100 mW cm−2. The study suggests that N,N‐dimethylformamide is a good solvent for the polymer electrolyte processing due to higher ac‐conductivity beneficial for the electrochemical device applications. © 2015 Wiley Periodicals, Inc.

“…There is also a change in position and intensity for the bands in the 3100-2800 cm À1 region, assigned to the C-H stretching modes, as well as a shift of the band at 989 cm À1 , assigned to the (C-H) deformation mode of O-CH 3 group, to a higher wavenumber value. Once again, all the changes in the spectra are indicative of the presence of interactions between the polymers, mainly involving the methyl group of the PMMA-co-BMA structure [35] . The Raman spectra of the samples are shown in Figure 2, and the main vibrational bands are also reported in Table 1, together with a tentative assignment based on literature [27,28,36,37] .…”

Chitosan/poly(methyl methacrylate-co-butyl methacrylate) (PMMA-co-BMA) blends were prepared via a solution blending method in the presence of formic acid. The compatibility of the bioblends was studied by different methods, such as Fourier transform infrared and Raman spectroscopy, micro-Raman imaging, thermogravimetric analyses, differential scanning calorimetry and scanning electron microscopic analysis. According to the obtained results, it has been concluded that the PMMA-co-BMA/chitosan bioblends are compatible in all the studied compositions. Specific interactions between carbonyl and methyl groups of the PMMAco-BMA structure and methyl, amine and amide groups of chitosan are responsible for the observed compatibility. INTRODUCTIONConcerns about environmental problems such as global warming, pollution of natural resources, renewable energy use and cost of synthetic polymers have motivated an intense research of sustainable polymer systems where at least one component is biodegradable or biobased [1] . The commercial importance of polymers also have increased the need of discover of new materials with specific properties and applications; for this purpose new polymers have been synthesized and chemical modifications in conventional polymers have also been proposed, but these methods are more complicated [2,3] . However, the mixture of two or more polymers, giving rise to a polymer blend, seems to be an economical method to obtain new polymeric materials with desirable properties, without the need of synthesizes specialized polymer systems [4,5] .
