Abstract

Herein, a flexible Poly(methyl methacrylate) (PMMA)/ polyaniline (PANi) blend nanocomposite consisting of zinc ferrite (ZnFe2O4) nanoparticles was developed utilizing a casting solution and co-precipitation techniques. X-ray diffraction (XRD) technique showed that all PMMA/PANi/ x wt % ZnFe2O4 polymers have a typical amorphous structure. The high-resolution transmission electron microscopy (HRTEM) and XRD techniques revealed that the average crystallite size of ZnFe2O4 is 19 nm. UV diffuse reflectance spectrophotometry technique was applied to study PMMA/PANi optical characteristics variations up on do** with different amounts of ZnFe2O4. The direct and indirect Eg values for PMMA polymer are 4.94 and 4.79 eV, respectively. As PMMA loaded with PANi, the Eg values decreased to 4.89 and 4.68 eV, respectively. The direct and indirect Eg values attained their lowest values of 4.28 and 3.64 eV as the amount of ZnFe2O4 became 2.5 wt % in the PMMA/PANi matrix. Enrichments in the whole linear/nonlinear optical parameters are accomplished by PANi/ZnFe2O4 do**. The fluorescence (FL) data of PMMA/PANi/x wt% ZnFe2O4 were studied in detail. As the percentage of ZnFe2O4 in the polymer matrix increased to 0.5 wt% in the polymer matrix, the maximum energy density value was achieved. The ac conductivity reached its highest value (3.25 × 1010 s−1 at 5.41 eV) as the amount of ZnFe2O4 became 2.5 wt % in the polymer matrix. Taking into account the findings of this study, the proposed: PMMA/PANi/x wt % ZnFe2O4 are considered great prospects for numerous applications.
