The goal of this study is to synthesize nanocomposite PVA/ Co_0.2Zn_0.2Cd_0.6Fe₂O₄ films with varying contents of Co_0.2Zn_0.2Cd_0.6Fe₂O₄ nanoparticles (x = 0, 0.2, 0.4, 0.6, 0.8) to improve the structural, optical, and mechanical characteristics of the examined materials. Casting technique is used to prepare PVA/ Co_0.2Zn_0.2Cd_0.6Fe₂O₄ films. X-ray diffraction, FTIR, UV–Vis spectroscopy, and Vickers Hardness were used to examine the effect of magnetic nanoparticle content on the structural, optical, and mechanical characteristics of PVA nanocomposite films. The refractive index rises from 1.4967 for pure PVA to 7.6511 for PVA + 0.8Co_0.2Zn_0.2Cd_0.6Fe₂O₄, allowing it to be employed in a variety of applications such as solar cell construction. Because of the presence of ferrite in the glass matrix, the average hardness values enhanced and increased from 90.7 to 114.2 MPa. The stress exponent (n) varies from 1.12 to 3.33, with grain boundary sliding as the deformation mechanism for x = 0, viscous glid for x = 0.2, 0.4, and 0.6, and dislocation climb for x = 0.8 nanocomposite thin films.

本研究的目标是合成具有不同Co _0.2 Zn _0.2 Cd _0.6 Fe ₂ O ₄纳米颗粒含量（x = 0, 0.2, 0.4, 0.6, 0.8）的纳米复合PVA/Co _0.2 Zn _0.2 Cd _0.6 Fe ₂ O ₄薄膜。改善受检材料的结构、光学和机械特性。采用流延技术制备PVA/Co _0.2 Zn _0.2 Cd _0.6 Fe ₂ O ₄薄膜。使用 X 射线衍射、FTIR、紫外-可见光谱和维氏硬度来检查磁性纳米粒子含量对 PVA 纳米复合薄膜的结构、光学和机械特性的影响。折射率从纯 PVA 的 1.4967 上升到 PVA + 0.8Co _0.2 Zn _0.2 Cd _0.6 Fe ₂ O ₄的 7.6511 ，使其可用于太阳能电池构造等各种应用。由于玻璃基体中铁素体的存在，平均硬度值从 90.7 MPa 增加到 114.2 MPa。应力指数 (n) 从 1.12 到 3.33 变化，x = 0 时晶界滑动为变形机制，x = 0.2、0.4 和 0.6 时为粘性滑动，x = 0.8 纳米复合薄膜时位错攀爬。
