    Recently, the introduction of inorganic nanoparticles, such as Manganese Chloride (MnCl2), as fillers in these polymers has emerged as an intriguing area of research, potentially enhancing their properties, and expanding their applications further. This study provides a comprehensive investigation into the influence of MnCl2 nanoparticles on PVA, forming PVA/ MnCl2 polymeric nanocomposite films. The research aims to enhance the understanding of the interactions between PVA and MnCl2, and the resultant structural, spectral, and radiation properties of the investigated nanocomposite films. The study incorporated the preparation of films with varying weight percentages of MnCl2 nanoparticles. X-ray diffraction patterns confirmed the presence of MnCl2 within the PVA structure and suggested strong interactions between the constituents. The FTIR spectral analysis was conducted to identify changes in the chemical bonds due to MnCl2 doping, employing spectral deconvolution to gain deeper insights into these changes. The study also considered density measurements using Archimedes' principle, providing insights into the physical properties of the nanocomposites. The radiation interaction properties of the polymeric nanocomposite films were evaluated to explore potential applications in radiation protection. The results shed light on the impact of MnCl2 doping on PVA and suggest the promising potential of these nanocomposites in numerous applications, including optoelectronics and radiation shielding. This study propels the understanding of polymer-nanoparticle interactions forward, offering valuable insights into the design and application of polymeric nanocomposites.
