Composites of transition metal oxides (TMOs)/Polymers have many modern technological, industrial, and biological applications. Co3O4 and CuO nanoparticles (Nps) were synthesized by sol-gel. Then they doped into poly(methyl methacrylate) (PMMA) via solution casting method. The obtained Nps and nanocomposite films were then investigated using several techniques. XRD and HR-TEM indicated the high purity of Co3O4 and CuO Nps of face-centered cubic (fcc) with 58 nm average particle size (Dav), and monoclinic structure with Dav = 35 nm, respectively. The amorphous nature of PMMA was influenced after mixing with these Nps. SEM and FTIR confirmed the interaction between Nps and the polymer chains. The pure film showed transparency of about 90% and Nps addition narrowed the optical bandgap effectively while keeping the films with high transmittance. CuO is more effective than Co3O4 on the optical parameters of the films.The dielectric constant improved after adding the Nps, while all films have a low dielectric loss.Additionally, the effects of Co3O4 and CuO on the ac conductivity, Argand plots, and the dielectric modulus are reported. Our nanocomposites are considered a promising candidate for nanotechnology-based devices such as electric stress control, film capacitors and anti-reflective coating for solar cell applications.

“…Doping with the oxides could encourage the PMMA's functional groups to have ordered states which affect the material's polarization. Moreover, the uniform distribution of the Nps on the PMMA surface facilitates the transportation of the charge carriers', resulting in higher values for ε' [35]. ) are listed in Table 2.…”

“…Furthermore, as shown in Figure 3, the peaks at (iv) 1648 cm −1 and (v) 1564 cm −1 represent the electrolyte's carboxamide and amine bands, respectively [55,56]. Moreover, the CH 2 scissoring and C-H bindings are responsible for the peaks seen in Figure 3 at (vi) 1422 cm −1 , (vii) 1390 cm −1 , and (viii) 1327 cm −1 , respectively [57][58][59][60]. Finally, the steep peak at (ix) 1077 cm −1 (Figure 3) could be attributable to C-O stretching, which has been observed by Mejenom and coworkers [61] and Poy and coworkers [62].…”

The solution cast process is used to set up chitosan: dextran-based plasticized solid polymer electrolyte with high specific capacitance (228.62 F/g) at the 1st cycle. Fourier-transform infrared spectroscopy (FTIR) pattern revealed the interaction between polymers and electrolyte components. At ambient temperature, the highest conductive plasticized system (CDLG–3) achieves a maximum conductivity of 4.16 × 10−4 S cm−1. Using both FTIR and electrical impedance spectroscopy (EIS) methods, the mobility, number density, and diffusion coefficient of ions are measured, and they are found to rise as the amount of glycerol increases. Ions are the primary charge carriers, according to transference number measurement (TNM). According to linear sweep voltammetry (LSV), the CDLG-3 system’s electrochemical stability window is 2.2 V. In the preparation of electrical double layer capacitor devices, the CDLG-3 system was used. There are no Faradaic peaks on thecyclic voltammetry (CV) curve, which is virtually rectangular. Beyond the 20th cycle, the power density, energy density, and specific capacitance values from the galvanostatic charge–discharge are practically constant at 480 W/Kg, 8 Wh/Kg, and 60 F g−1, for 180 cycles.
