通过掺入ZnCo2O4-CdS/TBAI/MWCNTs调控PMMA聚合物的光学与介电性能用于光电设备和储能应用

This work seeks to develop a novel composite polymer comprising polymethyl methacrylate (PMMA), ZnCo 2 O 4 /CdS, tetrabutylammonium iodide (TBAI), and multiwall carbon nanotubes (MWCNTs) for various optoelectronic applications. Loaded polymers with ZnCo 2 O 4 + CdS/TBAI/x wt% MWCNTs displayed significant absorbance in the UVB and UVC zones, irrespective of the MWCNTs doping level, while the polymer with x = 0.25% MWCNTs presented the maximum absorbance in the UVA zone. The least direct and indirect optical bandgap energies were achieved with PMMA containing ZnCo 2 O 4 + CdS/TBAI/x wt% MWCNTs. The highest refractive index (1.53) at 600 nm was attained with the polymer containing ZnCo 2 O 4 + CdS/TBAI/0.25 wt% MWCNTs. The doped polymer with 0.25 wt % MWCNTs demonstrates the greatest optical parameter values. The highest energy density value was recorded in ZnCo 2 O 4 + CdS, TBAI, and/or 0.2 wt% MWCNTs polymer. The incorporation of diverse fillers into PMMA resulted in an improvement in the dielectric constant AC conductivity.
