Description
Summary:PMMA polymer doped by multi-walled carbon nanotubes (MWCNTs) has attracted much attention as promising materials for photovoltaic and optoelectronic applications. The undoped poly(methyl methacrylate) (PMMA) and PMMA/MWCNTs nanocomposite films doped with varying concentrations of Zirconium dioxide nanoparticles (ZrO 2 NPs) are synthesized using the casting method. It is found that the transmittance ( T % ) decreases significantly as wt% = 5% of MWCNTs is injected into PMMA matrix. In addition, increasing the concentration of ZrO 2 NPs into PMMA- MWCNTs nanocomposite thin films results in a further reduction of the transmittance and a further increase of the reflectance ( R % ). The optical band gap energy (E g ) of PMMA-MWCNTs/ZrO 2 NPs decreases from 4.063 eV to 3.845 eV upon injection of 5% of MWCNTs and gradually increasing the ZrO 2 concentration in PMMA matrix. Furthermore, other essential optical parameters are estimated using different classical models such as Drude, Spitzer-Fan, Sellmeier, and Wemple–DiDomenico (WDD). Interestingly, thermal stability of PMMA-MWCNTs nanocomposite films is enhanced dramatically upon increasing the content of ZrO 2 NPs. The synthesized nanocomposite thin films could be potential candidates for fabrication realistic scaled optoelectronic devices.
