This study addressed the preparation of multicomponent samples composed of a double polymer matrix of polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) reinforced with metal oxides (zinc oxide and iron oxide) and carbon fibers. Different slides (A1-A5) with various compositions were prepared to study the relative influence of the different components on the physical, chemical, and structural properties of the resulting composites. X-ray diffraction (XRD) analysis revealed the presence of distinct crystalline peaks at specific diffraction angles (31.65°, 33.10°, 36.31°, 47.68°, 56.60°, 62.84°, and 67.97°), confirming the crystalline structures of zinc sulfate. Furthermore, the probe peaks at 19.65° are attributed to the semicrystalline nature of the polymers used. The analysis also revealed the presence of iron oxide crystal phases at angles (33.10°, 40.86°, 49.4°, 53.94°, and 63.98°).SEM images at different magnifications (200 and 500)nm  revealed a completely flat morphology, featuring spherical nanoparticles and cubic clusters within an outward-facing polymer matrix. This included a partial difference in the force distribution between the different bands, reflecting the effect of the ratio on the morphology. Energy distribution analysis (EDS) with elemental distribution mapping demonstrated the simultaneous presence of zinc, iron, carbon, and carbon in the composition and the relative distribution of the elements between the different bands. The results obtained indicate the potential for these samples to be used in diverse applications such as photocatalysis, antimicrobial materials, electronic applications, and specific analyte delivery systems.
