Synthesis and characterization g‐C₃N₄‐doped PMMA polymeric nanocomposites films for electronic and optoelectronic applications

Abstract

Solution casting was used to synthesis polymethyl methacrylate (PMMA) nanocomposites with graphitic carbon nitride (g‐C3N4) nanoparticles in various percentages (0.033, 0.166, 0.33, 1.665, and 3.3 wt%). XRD patterns confirmed the amorphous nature of PMMA/C3N4 nanocomposites. Optical constants are obtained at room temperature in the 200–2500 nm wavelength range. The optical band gaps of PMMA/C3N4 doped films, both direct and indirect, are measured and have values change from 4.8 to 2.32 eV for Enormalgind and changes from 5 to 3.7 eV for Enormalgnormald. The refractive index values of the materials were also calculated using Moss, Reddy, Anani, and Kumar‐Singh relationships with average values vary from (2.109 to 2.529) and vary from 2.155 to 2.32 for indirect and direct transition, respectively. The dielectric constant, dielectric loss, and AC electrical conductivity at RT and the g‐C3N4 doping level was examined as frequency variables from 100 to 1 MHz. In consideration of Jonscher's universal power law, the variation of σAC with frequency was examined. The addition of C3N4 appears to raise the σAC of the studied films, making them attractive for semiconductor applications. According to the optical limiting results, the samples doped with g‐C3N4 are severely attenuated for the laser beam of 638.2 nm. PMMA doped with g‐C3N4 is a viable contender for electronic and optoelectronic applications, particularly laser power reduction.

Linear and Nonlinear Optical Properties of PVA:SA Blend Reinforced by TiO2 Nanoparticles Prepared by Flower Extract of Aloe Vera for Optoelectronic Applications

“…To this end, prepared samples of nanocomposites of TiO 2 NPs doped in the host blend of PVA:SA were examined for their utility in the optical limiting of CUT-OFF laser filters utilizing a continuous He-Ne laser working at 632.2 nm. In this study, the aperture Z-scan characteristics can be used to measure the prepared samples' nonlinear influence power magnitudes in watts per area [112]. The synthesized nanocomposites' output influence power and their normalized influence power are shown against the percentage of TiO 2 , as shown in Figure 13, where the normalized power was represented as the equivalent ratio between input influence power and output influence power.…”

Tuning the structural, optical, and photocatalytic properties of V 2 O 5 /PMMA nanocomposite films for methylene blue photodegradation

“…PMMA has diffraction peaks of and , this is the polymer's crystalline phase. Mervat I Muhammed et al, estimated the diffraction peaks of PMMA at comparable values (Muhammed et al 2022). The 1st-peak shape represents that extended polymer chains have been packed, while the 2nd-peak showed that the major chains had been ordered with gradually decreasing in their intensity (Rathika et al 2018).…”

“…6a, as the wavelength gets longer, the extinction coe cient rises, suggesting that the fraction of light lost due to scattering rises as well. The rise in the amount of V 2 O 5 NP content attributable to the rise in the absorbent portion of incident light is increased, and therefore, the energy loss occurs (Muhammed et al 2022).…”
