In this research, polymer composite sheets were developed by blending poly (vinylidene fluoride-co-hexafluoropropylene) or P(VDF-HFP) with varying concentrations of barium sulfate (BaSO4) for X-ray shielding applications. The photon counting technique was used to evaluate the characteristics through linear attenuation coefficient. Surface properties, including surface morphology, hydrophobicity, and energy, analyzed using an atomic force microscope (AFM) a water contact angle machine. Scanning electron microscopy (SEM) employed investigate microstructural distribution dispersion BaSO4 particles within matrix, providing insights into composite’s uniformity structural integrity. Additionally, bulk properties sheets, such as crystal structures, tensile strength, thermal stability, examined. results demonstrate that increasing concentration in BaSO4/P(VDF-HFP) significantly improves their capabilities. Moreover, higher enhance material’s flexibility, highlighting potential these composites advanced radiation
